Hi,
as Udo wrote, you can't use jstl inside tc:sheet!
Or to be more precise: the var param of tc:sheet is not available when
jstl iterates, because jstl evaluates before tobago starts renderring.
I also can't imagine how you do this with component binding, because
this is also done before rendering starts. Can you explain how you do
this?
But there is a way to solve this, you need binding to a extended
UIPanel implementation which drops and recreates children depending on
sheets var in each process* method.

Volker
