[jboss-user] [JBoss Seam] - selectBooleanCheckbox and dataScroller

[FabBoco]

Hi,

I have a dataTable that uses a dataScroller and selectBooleanCheckbox.

First problem is that selected items get deselectd when I move from one page to the other.

So I tryed to manage selected items myself. Second problem is that when I move from one page to the other the findAll function is called but selections is empty (see attached code).

Please help me!

Thank you

Regards 

Fab.
