[jira] Created: (TRINIDAD-2019) Class Cast Exception on
StampState$TableState when using Mojarra
Class Cast Exception on StampState$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.

[jira] Commented: (TRINIDAD-2019) ClassCastException on
StampState$TableState when using Mojarra
Posted by "Andy Schwartz (JIRA)" <de...@myfaces.apache.org>.

Andy Schwartz commented on TRINIDAD-2019:
-----------------------------------------
We ran into another case where Mojarra was incorrectly inserting a UIPanel wrapper inside of a facet. See:
http://java.net/jira/browse/JAVASERVERFACES-1726
Is it possible that you are running against a version of Mojarra that does not include this fix (ie. pre-2.0.4)?
Since the incorrect insertion of UIPanel components can have all sorts of unexpected side effects, I would recommend that we attempt to secure a fix for this problem at the Mojarra level rather than working around this in Trinidad.
