Allow f:event listener="#{cc.preRenderViewCallback}" work
---------------------------------------------------------
Key: MYFACES-3289
URL: https://issues.apache.org/jira/browse/MYFACES-3289
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
This is one of the "most wanted" hacks to do. Long time ago I tried it without
success, but now I finally founded and alternative. Following the same
principle of MYFACES-3287, we can use a "find component expression" to locate
the composite component later and setup the environment correctly. As with
MYFACES-3287 if the component is inside a datatable, the code on the listener
will only execute once, and not per row, which is something expected and the
affected properties on the component has the same limitations.
The other part of the hack include use a listener to PostAddToViewEvent to
subscribe the listener after the tree is built, so we can calculate the "find
component expression" correctly.
