| /** |
| * Method annotation used for methods that should be invoked when the page is first attached to a request. This is |
| * useful for initializations that should occur on each request that involves the page. Often, such initializations will |
| * be balanced by cleanups when the page is detached. |
| * <p/> |
| * PageAttached methods should take no parameters and return void. They must either have this annotation, or be named |
| * "pageAttached". |
| * <p/> |
| * To be clear: methods with this annotation (or name) are still invoked even in Tapestry 5.2, which does away with |
| * the page pool. |
| * |
| * @see PageDetached |
| * @deprecated In Tapestry 5.3, with no replacement (attach logic no longer meaningful now that pages are singletons). |
