------------------------------------

Thanks for the clarification [~alsha].  Reverting back to the pre-4.3.4 tree visiting
pattern would be a step backwards.  I suggest we address this use case by creating a new
meta-component for the tabPanel: {{@headers}} which would render that tab headers
explicitly when the component is built.

    Affects Versions: 4.3.4
         Environment: java 7,

              Labels: regression

 I use ajax to update the header label of rich:tab. That is why label is placed in a
header-facet. Since RF 4.3.4 this does not work:

 testBean is a simple session-scoped HashMap.
