Hi all,
Thanks for your interest; that's the aswer i was
looking for, i did't understood the meaning of those
"*Var" attributes; now it's all clear, thank you very
much, hope for the others to. I have to admit that i
was using it wrong, and wondered why it was't working
:).
In this case what it could be done, so a backend bean
it will be informed on the page index changed? maybe a
"pageSelectionChange" listener will make things more
clear? are there any plans of implementing such a
listener, similar to "tabChangeListener" used for
tabs?
Thanks again,
Regards,
Catalin
