Jakob Korherr commented on MYFACES-2826:
----------------------------------------
This should work now. The problem was that we were only checking if cc.attrs.
occurs in the expression to indicate a composite component methodexpression,
but we did not check if cc.attrs. only occurs as a parameter for the method
invocation.
