Hi Thomas,
I think the problem we were talking about, is kind of
outdated...i did't understood the usage of those
"*Var" attributes, like "pageIndexVar" for
dataScroller tag. Now it's clear. That attribute is
used as the "var" attribute for the dataTable tag, so
it's not meant to be used as i wanned. But maybe you
have a solution, for the more general need, to be able
to be informed about the page selection change by the
dataScroller or by the dataTable...i can't tell which
one should do the job. Any ideeas?
Regards,
Catalin
