   <title>Jakarta Tapestry - What's New</title>
  </header>

 <body>

 ... or perhap's, "What's Old". These are release notes from earlier versions of Tapestry. More recent changes
 are in a different format, on the <link href="site:changes">Change Log page</link>.

 <section><title>Release 3.0-beta-1</title>
 <ul>
 <li>Major refurbishment of the Virtual Library example to use all the latest and greatest Tapestry facilities.</li>
 <li>Removed the "rows" and "columns" parameters from TextArea; use informal parameters "rows" and "cols" instead.</li>
 <li>Removed unused/unneeded exceptions <code>RollbackException</code> and <code>PageRecorderSerializationException</code>.</li>
 <li>The default for the <link href="http://jakarta.apache.org/tapestry/doc/ComponentReference/Hidden.html">Hidden</link> component is now to encode its parameter.</li>
 <li>Ugraded to OGNL 2.4.2.</li>
 <li><link href="http://jakarta.apache.org/tapestry/doc/ComponentReference/Shell.html">Shell</link> comp;onent now allows multiple stylesheets.</li>
 <li>Added a <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/util/io/DataSqueezer.html">DataSqueezer</link> adaptor for
 <code>Enum</code> types.</li>
 <li>Switched over to using JBoss 3.0.6 for demos.</li>
 <li>Renamed method <code>generateAttributes()</code> to <code>renderInformalParameters()</code> in
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/AbstractComponent.html">AbstractComponent</link>.</li>
 <li>Added support for the informal parameters of a component to be passed down to a contained component
 using the inherit-informal-parameters attribute. </li>
 <li>Added <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/IRequestCycle.html">IRequestCycle</link>.activate() as a replacement for setPage().
 Besides setting the page to be rendered, it also invokes page.validate() and handles the page redirections.</li>
 <li>Added addValidateListener() and removeValidateListener()
 to <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/IPage.html">IPage</link>.</li>
 <li><link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/util/io/DataSqueezer.html">DataSqueezer</link>: Squeezed strings are now always prefixed with 'S'</li>
 <li>Added mechanism for checking that super-class implementations of key methods are invoked.</li>
 <li>Added checks that <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/IPage.html">IPage</link> methods
 <code>validate()</code> and <code>detach</code> are properly overriden by subclasses.</li>
 <li>Changed Form, Hidden and ListEdit so that all hidden fields are written out with the &lt;form&gt; tag.</li>
 <li>Added new features to the script specification, bumping its DTD to 1.3. It is now possible
 to generate page-unique ids from within the script (using the new <code>unique</code> attribute
 on <code>&lt;let&gt;</code>, as well as to
 render a block only once per page render (using <code>&lt;unique&gt;</code>)
 </li>
 <li>Integrated Per Norrman's vastly improved <link href="http://jakarta.apache.org/tapestry/doc/ComponentReference/DatePicker.html">DatePicker</link> component</li>
 </ul>

 [ 18249 ] file upload using Commons FileUpload
 [ 17905 ] Link to mailing list and archives is wrong.
 </pre>

 </section>
 <section><title>Release 2.4-alpha-4</title>

 <ul>
 <li><b>All packages have been renamed from <code>net.sf.tapestry</code> to <code>org.apache.tapestry</code></b>.</li>
 <li>Several non-ASL libraries (including Jetty) have been removed from both CVS and the distribution.  To
 build Tapestry and run the demos is now more involved; it requires obtaining several external dependencies.
 The Tapestry distribution is much smaller, however.  This was done for licensing reasons.
 Sorry.</li>
 <li>Expression bindings in HTML templates are now in the format
 <code><i>attribute</i>="ognl:<i>expression</i>"</code>.</li>
 <li>String bindings (to localized strings) in HTML templates are now in the format
 <code><i>attribute</i>="string:<i>key</i>"</code>.</li>
 <li>Allow &lt;set-property&gt; element of specification to specify the expression as an attribute or
 as wrapped character data.</li>
 <li>The interfaces for <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/valid/IValidationDelegate.html">IValidationDelegate</link>,
  <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/valid/IValidator.html">IValidator</link> and
   <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/valid/ValidatorException.html">ValidatorException</link>
 changed incompatibly.  This will only be an issue if you have created custom validation delegates or custom
 validators.</li>
 <li>Added methods to <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/valid/IComponentStrings.html">IComponentStrings</link> for formatting localized strings
 with arguments.</li>
 <li>Remove ejb.jar and any direct dependencies on javax.ejb classes (application servers are responsible for properly replicating
 EJBObject and EJBHome instances).</li>
 <li>Added a <code>createRequestCycle()</code> method to
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/engine/AbstractEngine.html">AbstractEngine</link>.</li>
 <li>Moved the invocation of the
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/IMonitor.html">IMonitor</link> method  <code>serviceEnd()</code>
 to always occur after the invocation of <code>serviceException()</code>.</li>
 <li>The <link href="http://jakarta.apache.org/tapestry/doc/ComponentReference/Upload.html">Upload</link> component now works with the enclosing Form
 to automatically set the encoding type to <code>multipart/form-data</code>.  It is no longer necessary to set
 the <code>enctype</code> attribute of the Form.</li>
 <li>Removed the code related to making copies of persistent properties.</li>
 <li>Removed non-ASL libraries from CVS.  These files will need to be downloaded separately.</li>
 <li>Removed some of the old tutorials, leaving just the Workbench and Virtual Library as examples.</li>
 <li>Removed the "Demo" pages from the web site, until we find a stable home.</li>
 </ul>

 </section>
 <section><title>Release 2.4-alpha-3</title>

 <ul>
 <li>
 Reorganized the packaging into a binary distribution (which includes documentation) and a second,
 smaller, source-only distribution.</li>
 <li>Renamed the JARs, stripping off the "net.sf." prefix.</li>
 <li>Updated all examples to use the 1.4 Specification DTD.</li>
 <li>Refactored (severely) the relationship between services and link components, splitting
  the rendering portion of links into a separate interface.</li>
 <li>Upgrade to McKoi database 0.94h.</li>
 <li>Tapestry will now create properties for connected parameters, if the properties
  do not already exist (or are abstract).</li>
 <li>Renamed the <code>java-type</code> attribute of the <code>&lt;parameter&gt;</code> element (in component
  specifications) to <code>type</code> (for the 1.4 DTD).</li>
 <li>Allowed more elements to specify values as character data inside the element as an alternative
 to using a particular attribute (useful for complex OGNL expressions).</li>
 <li>Continued extending the JUnit test suite.</li>
 <li>Deprecated the <code>PageCleanupListener</code> interface and removed support for it.</li>
 </ul>

 <pre>
 [ 665622 ] net.sf.tapestry.html.Frame uses old DOCTYPE
 [ 675882 ] option component generates invalid HTML
 [ 622691 ] Full release
 [ 679655 ] Upload component very slow on file uploads
 </pre>

 </section>
 <section><title>Release 2.4-alpha-2</title>

 <ul>
 <li>Made improvements to how Tapestry handles arrays of objects and scalars</li>
 <li>Upgrade demos to deploy into JBoss 3.0.4</li>
 <li>Merge in changes from Tapestry 2.3</li>
 <li><code>&lt;binding&gt;</code> elements may now specify the expression as the parsed data
 instead of the expression attribute</li>
 <li>The template extension may now be overriden using the configuration property <code>net.sf.tapestry.template-extension</code></li>
 <li>Added support for declarative transient and persistent properties via <code>&lt;property-specification&gt;</code> element in page and component specifications.  Tapestry will create (on the fly) a subclass with the necessary accessor methods and fields, as well as any necessary notification and cleanup methods. </li>
 </ul>

 <pre>
 [ 594878 ] Deploy Tapestry into JBoss 3.0.4
 [ 672743 ] Pages Implementing Listeners cause NPE
 </pre>

 </section>
 <section><title>Release 2.4-alpha-1</title>

 <ul>
 <li>
 Added support for specifying expressions in the component template.  Expressions
 are specified as attributes with the format "<code>[[ <i>expression</i> ]]</code>".
 The brackets and leading and trailing whitespace are removed.
 Expressions specified this way are the equivalent of the
 <code>&lt;binding&gt;</code>
         element in a specification.
 </li>
 <li>
 Tapestry now supports <i>implicit components</i>.  Implicit components are
 declared exclusively in the containing component's template (instead of in
 the containing component's specification) using a special
 <code>jwcid</code> syntax:
 <code>@<i>type</i></code> (for anonymous components) or
 <code><i>id</i>@<i>type</i></code> (for named components). Implicit
         components are especially useful for components that take no parameters,
         but may also make use of template expressions.
 </li>
 <li>
 Added support for the <code>&lt;listener-binding&gt;</code> element in page
 and component specifications.  This allows a listener method to be provided,
 directly within the specification, as a script written in a
 <link href="http://jakarta.apache.org/bsf">BSF</link>-supported language.
 </li>
 <li>
 A number of non-backwards compatible changes were made to several
 framework interfaces to support more flexibility on where specifications
 and templates may be located, but these should not affect the overwhelming
 majority of Tapestry users.  In addition, private assets and context assets
 may also be relative. <br/>
 Private assets are relative to the component
 specification which declares them, context assets are relative to the
 application servlet (within the servlet context).
 </li>
 <li>
 Moved the Inspector out of the framework and
 into the contrib library.
 </li>
 <li>
 Created smarter checks for stale sessions for
 ActionLink, DirectLink and Form. The action and direct services used by
 the components now encode whether the application was stateful into the
 URL. The stateful check only occurs if the application was stateful when
 the URL was rendered.
 </li>
 <li>
 Changed Form to record the exact ids generated during the render (it used to just store the count).
 This allows a more useful exception message to be generated
 for the
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/StaleLinkException.html">StaleLinkException</link>.
 </li>
 <li>
 Changed the default StaleLink page to have a
         message property, and to display the message from the
         StaleLinkException.
 </li>
 <li>
 Components (and even pages) can now implement page listener interfaces
 (<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageDetachListener.html">PageDetachListener</link>,
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageRenderListener.html">PageRenderListener</link> or
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageCleanupListener.html">PageCleanupListener</link>)
 and <code>finishLoad()</code> will <i>automatically</i> add them as a listener to the
         corresponding page events.
 </li>
 <li>
 The entire mechanism used to store persistant
         page properties has been revised.
 </li>
 <li>
 Implemented a number of improvements to
 <link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/util/pool/Pool.html">Pool</link>
 to support greater flexibility in managing objects stored into and discarded
 from the pool.
 </li>

 </ul>

 <pre>
 [ 653358 ] IPage.getName() == qualified name
 [ 608768 ] Changes saved AFTER IPage.detach()

	are specified as attributes with the format "<code>[[ <i>expression</i> ]]</code>".
	The brackets and leading and trailing whitespace are removed.
	Expressions specified this way are the equivalent of the
	<code><binding></code>
	element in a specification.
	</li>
	<li>
	Tapestry now supports <i>implicit components</i>. Implicit components are
	declared exclusively in the containing component's template (instead of in
	the containing component's specification) using a special
	<code>jwcid</code> syntax:
	<code>@<i>type</i></code> (for anonymous components) or
	<code><i>id</i>@<i>type</i></code> (for named components). Implicit
	components are especially useful for components that take no parameters,
	but may also make use of template expressions.
	</li>
	<li>
	Added support for the <code><listener-binding></code> element in page
	and component specifications. This allows a listener method to be provided,
	directly within the specification, as a script written in a
	<link href="http://jakarta.apache.org/bsf">BSF</link>-supported language.
	</li>
	<li>
	A number of non-backwards compatible changes were made to several
	framework interfaces to support more flexibility on where specifications
	and templates may be located, but these should not affect the overwhelming
	majority of Tapestry users. In addition, private assets and context assets
	may also be relative. <br/>
	Private assets are relative to the component
	specification which declares them, context assets are relative to the
	application servlet (within the servlet context).
	</li>
	<li>
	Moved the Inspector out of the framework and
	into the contrib library.
	</li>
	<li>
	Created smarter checks for stale sessions for
	ActionLink, DirectLink and Form. The action and direct services used by
	the components now encode whether the application was stateful into the
	URL. The stateful check only occurs if the application was stateful when
	the URL was rendered.
	</li>
	<li>
	Changed Form to record the exact ids generated during the render (it used to just store the count).
	This allows a more useful exception message to be generated
	for the
	<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/StaleLinkException.html">StaleLinkException</link>.
	</li>
	<li>
	Changed the default StaleLink page to have a
	message property, and to display the message from the
	StaleLinkException.
	</li>
	<li>
	Components (and even pages) can now implement page listener interfaces
	(<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageDetachListener.html">PageDetachListener</link>,
	<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageRenderListener.html">PageRenderListener</link> or
	<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/event/PageCleanupListener.html">PageCleanupListener</link>)
	and <code>finishLoad()</code> will <i>automatically</i> add them as a listener to the
	corresponding page events.
	</li>
	<li>
	The entire mechanism used to store persistant
	page properties has been revised.
	</li>
	<li>
	Implemented a number of improvements to
	<link href="http://jakarta.apache.org/tapestry/doc/api/org/apache/tapestry/util/pool/Pool.html">Pool</link>
	to support greater flexibility in managing objects stored into and discarded
	from the pool.
	</li>
