Thomas Andraschko commented on MYFACES-4690:
--------------------------------------------
Ok, TBH i dont now if its a bug in MyFaces or Mojarra
or both handle it not correct for 100%
the XML above shows our "consequential error"
but on the other hand, your usecase is not valid
update="" takes a expression and not a whole clientId.
Currently you do a relative lookup, which will be triggered from commandButton,
which actually translates to:
{code:xml}
update="testDialog">
{code}
and is this relative context, it solves to: "testDialog:testDialog".
You actually like to resolve to "testDialog", as "testDialog:testDialog" doesnt
even exist in the rendered markup.
You should actually use:
{code:xml}
update=":#{cc.clientId} #{cc.attrs.update}">
{code}
> Facelet Compatibility: AJAX update fails for components in composite
> components with same ID

> Key: MYFACES-4690
> URL: https://issues.apache.org/jira/browse/MYFACES-4690
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 4.0.2
> Reporter: Manuel K
> Priority: Major
> Attachments: image-2024-11-05-08-20-31-951.png,

>
> Reproducer: [^primefaces-test-dialog-cc-id-problem.zip]
> Clicking on show dialog opens the dialog, but clicking on cancel does not
> close the dialog even though it should.
> Composite component representing PrimeFaces dialog added to page:
> !image-2024-11-05-08-20-31-951.png!
> "dialogTest" composite component contains another composite component with
> the same ID:
> !image-2024-11-05-08-25-07-002.png!
> If the underlined ID "testDialog" is changed to something else, it works. If
> it's the same, it fails.
> Works in Mojarra.
> Please let me know if you need additional information! Thank you very much in
> advance!
