Leonardo Uribe commented on MYFACES-2561:
-----------------------------------------
It is a know problem about the semantic of #{cc}. In this case it resolves to
the closest composite component and in that case is the same one. See this two
topics on jsr-314-open mailing list (specially the first one):
[jsr-314-open] #{cc} semantics
[jsr-314-open] cc.parent mystery
In http://wiki.jcp.org/wiki/index.php?page=JSF+2.0+Rev+A+Change+Log it appears
like:
C034 Change Modify table 5-10 to state that implicit object cc
returns the current composite component, relative to the composite component
markup page in which the expression appears
I'm keeping an eye on this change (there is other related to cc.parent
resolution). It could be good to know what ri does in this case.
It could be good to have a patch for this one.
