> 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.
