Werner Punz resolved MYFACES-4771.
----------------------------------
Resolution: Fixed
> Regression 2.3.10 -> 2.3.11
> ---------------------------
>
> Key: MYFACES-4771
> URL: https://issues.apache.org/jira/browse/MYFACES-4771
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 2.3.11, 2.3.12
> Reporter: Jonathan S. Fisher
> Priority: Major
>
> Ajax render/execute ids wrongly prefixed with form's naming container
> (2.3.11+)
> Since f7e0547 (MYFACES-4538), _transformList runs every render/execute id
> through _remapNamingContainer. Without a namespaced view root, every id the
> server resolved gets the prefix of the form's nearest naming container.
> To Reproduce: put an h:form inside composite "comp" has <f:ajax
> render=":target"/>. The server renders render:'target'. 2.3.10 posts
> "target", and 2.3.11+ posts "comp:target". The update is skipped silently.
> The server already strips the leading ":", so the client cannot tell absolute
> ids from relative ids. With rootNamingContainerId == "", the absolute check
> never matches.
> Fix: return the elements unchanged when rootNamingContainerId is empty. A
> namespaced view is unaffected, because its ids carry the root prefix and
> already pass through unchanged.
> {code:javascript}
> if (!rootNamingContainerId) {
> return elements;
> }
> {code}
> I'll open a PR on github shortly. Tested on 2.3.13-SNAPSHOT and solves the
> problem.
