Shane Petroff commented on TRINIDAD-1006:
-----------------------------------------
Based on one of Matthais' comments on the users list, I've changed a bit of the
code. It works better now in the sense that both fields get updated when one
uses the declarative version, but the programmatic one is still broken. Is
there something else which needs to be set up?
public void returnedFromPage2( ReturnEvent event)
{
if (event.getReturnValue() != null)
{
Object[] array = (Object[]) event.getReturnValue();
System.out.println( "returned value " + array[0] );
setSessionText(array[0].toString());
UIComponent comp = event.getComponent().findComponent("txtID");
RequestContext afContext = RequestContext.getCurrentInstance();
afContext.addPartialTarget(comp);
}
}
> PPR does not work for components setup programatically

> Key: TRINIDAD-1006
> URL: https://issues.apache.org/jira/browse/TRINIDAD-1006
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 1.0.6-core
> Environment: Win2K, Tomahawk 6.0.14, Firefox 2.0.0.12
> Reporter: Shane Petroff
> Priority: Blocker
> Attachments: testApp.war
>
>
> I've set up two sets of components which are supposed to be functionally
> identical, but they do no behave in the same way. Each pair is composed of a
> tr:inputText and a tr:commandButton. The first 'version' is composed into a
> standard page, and the second is created programmatically.
> The normal declarative version works fine, but the programmatic one does not.
> To get to this state, I used the maven create archetype
> (http://wiki.apache.org/myfaces/MyFaces_Archetypes_for_Maven) to generate a
> hello world app. I dropped back the version numbers for JSF 1.1 (tr v 1.0.6),
> then deployed to Tomcat 6.0.14. The return events are 'heard', but the PPR
> refresh never succeeds. The files below contain the respective changes to the
> hello world app. There are no errors either on the server or js, but the
> refresh never happens. I can't decipher the posts associated with the PPR
> activity. Any help appreciated, my only fall-back now is to drop Trinidad,
> thanks.
