But doesn't that break spec?
Are you returning the UIComponent itself or some proxy instance?

Yes - but I extended the findComponent concept for data table to allow
scoped id's with a row-identifier included, so this is now much the
same as a client-id, except if the renderer does a conversion.
So what Dave wants ought to work. In the latest nightly build and
several before them.

findComponent has nothing to do with client ids. They work off of
different logic.

Hmmm...
yes, you should be able to search from the view-root no problem.
Can you debug a little through find-component?
I have a working test-case in tomahawks test source, plus we use the method
successfully in the AJAX part.

findComponent return null for a valid clientId
----------------------------------------------
Key: MYFACES-1110
URL: http://issues.apache.org/jira/browse/MYFACES-1110
Project: MyFaces
Type: Bug
Components: Implementation
Versions: Nightly
Environment: JBoss 4.0.3, XP
Reporter: Dave
Assignee: Martin Marinschek
Priority: Critical
In a PhaseListener, first get all the clientId(s) with queued messages, then
try to find the components. But ViewRoot.findComponent(clientId) return null.
public void beforePhase(PhaseEvent event) {
FacesContext context = event.getFacesContext();
UIViewRoot root = context.getViewRoot();
Iterator<String> itr = context.getClientIdsWithMessages();
while (itr.hasNext()) {
String clientId = itr.next();
UIComponent component = root.findComponent(clientId);
// ERROR: component is null
....
}
}
From debugger, clientId is
emp:empForm:empTable:1:salary:_idJsp144
The clientId is returned from context.getClientIdsWithMessages();
It must be valid, but root.findComponent() returns NULL.
JSF should have the following API
FacesContext.getComponentsWithMessages();
which is better than getClientIdsWithMessages();
