Class Cast Exception on StampState$TableState when using Mojarra
----------------------------------------------------------------
Key: TRINIDAD-2019
URL: https://issues.apache.org/jira/browse/TRINIDAD-2019
Project: MyFaces Trinidad
Issue Type: Bug
Affects Versions: 2.0.0-alpha-2, 2.0.0-alpha
Reporter: Scott O'Bryan
Assignee: Scott O'Bryan
When a UIX Collection object is put inside of a component (such as a switcher
which has a list of facets) and it then put inside of another panel collection,
Mojarra can sometimes change the heirarcy of the stamped component by inserting
a UIPanel during a PPR. This has the effect of generating a ClassCastException
when StampState$TableState tries to cast the component to a UIXCollection so
that table-in-table can be supported.
This issue ONLY happens in this specific circumstance where the switcher has
only one component in the facet and we have a collection inside of another
collection. Although this is a bug with Mojarra, the patch is fairly straight
forward and if we see a UIPanel instead of a UIXCollection, we should, instead,
sent the StampState to the UIPanel's single child.
