Persitent page properties are not set before PageAttachListener#pageAttached
method is fired
--------------------------------------------------------------------------------------------
Key: TAPESTRY-872
URL: http://issues.apache.org/jira/browse/TAPESTRY-872
Project: Tapestry
Type: Bug
Components: Web
Versions: 4.0
Environment: Windows 2000 Proffesional SP4
Apache Tomcat 4.1
Tapestry 4
Reporter: Petr Marek
Persisten page property in pageAttached method is not set to stored property
value before this listener is notified.It is set after pageAttached is called,
not before. It means property values stored in session can not be accesses in
pageAttached method. If II understood specificaion correctly, it should be set
before pageAttached is called.
In javadoc specification for PageAttachListener#pageAttached(PageEvent event)
it is written:
"... Notifications occur after persistent page properties have been restored,
but before the page is
activated (if it is activated). ..."
Here is simple example:
ZTest.page specification:
<page-specification class="ZTest">
<property name="name" persist="session"/>
<property name="nameNoSession"/>
</page-specification>
Asociated java class:
public abstract class ZTest extends BasePage implements PageAttachListener
{
public abstract String getName();
public abstract void setName(String name);
public abstract String getNameNoSession();
public abstract void setNameNoSession(String nameWithoutSession);
public void pageAttached(PageEvent event) {
String name = this.getName(); // <-- here is returned null
every time even if value is stored to session
String nameWithoutSession = this.getNameNoSession();
}
/**
* Listener
* <at> cycle
*/
public void namelistener(IRequestCycle cycle) {
String name = this.getName(); // <-- here is correctly returned
value stored in session
String nameWithoutSession = this.getNameNoSession();
cycle.activate("Home");
}
}
