[exoplatform] Problem with missing scrollbar

[Cédric TRAN-XUAN <cedric.tran-xuan@xxxxxxxx>]

Hi all,
I have inserted a UIFormTabPane within a component that extends a 
UIContainer but I have trouble with the display: indeed, my 
UIFormTabPane is big and I cannot see the bottom ui components of the 
tab pane. So, I was wondering how to add a scrollbar and more generally, 
how the scrollbar mechanisms are dealt (who, how and when).

Thanks in advance,

Cédric.
