<title>Features We'd Like To See - The Struts Project Wish List</title>
</properties>
<body>
<section name="Introduction" href="Intro">
<p>Application frameworks, like the applications we build with them,
never seem to be completed. The following major areas of improvement
are being considered for implementation in a future version
of Struts. </p>
<p>Which features are implemented first depends greatly on
individual developers becoming involved in the process. Many key
features in Struts grew out of code first distributed on the mailing
list. If there is a feature here that you need, or already have, please
start a thread and show us the code!</p>
<p class="center"><a href="../faqs/helping.html#release"><strong>So, when is the next release coming out?</strong></a></p>
<p>An external development that is likely to affect the development of
Struts 1.1 will be the emerging Standard Tag Library, being produced under
the <a href="http://www.jcp.org/jsr/detail/52.jsp">Java Community Process</a>.
A very early release is now available at
<a href="http://jakarta.apache.org/taglibs/doc/jsptl-doc/intro.html">Jakarta
Taglibs</a>.</p>
<p>The existing Struts tags were used as input to the standardization process,
but in the case where standard tags with similar functionality are adopted,
we should migrate Struts tags to maintain maximum compatibility with the
new standard library.</p>

</ul>
<p>See also the Service Manager packages in the contrib folder.</p>
<p>The wish list tasks are divided into functional areas that correspond
to the major components of the Struts Framework. References in square
brackets are the Java package containing the corresponding source code.
Listing a task here is not a guarantee that it will be present in the
next release. Again, whether a wish becomes a feature depends on whether
there are volunteers who choose to work on the task. </p>

<code>Tasks</code> that are combined according to configuration
information (including flow control and iteration support) in the
<code>struts-config.xml</code> file. Support for workflow processing
would be provided by a set of standard <code>Actions</code>, and
will offer an alternative mechanism (not a replacement of Actions)
to organizing your business logic.</p>

<p>Retrofit the Struts controller framework with supports for event
generation (and the corresponding registration of listeners) for all
interesting events created by the framework. The list of interesting
events will undoubtedly be influenced by changes related to other
work items on this list (such as workflow processing and standard
validations), so work on this should be coordinated with those
changes.</p>
