Hi Volker,
By component binding i used actually your tip for using rendered attribut
(thank you!)
After creating the main panel and his children panels for each row of the
sheet, i've
defined the rendered attribut of the children panels with:
ComponentUtil.setBooleanProperty(childPanel /* the i child panel */,
TobagoConstants.ATTR_RENDERED, "#{" + sheetVar
+ ".index == "
+ item.getIndex() /* for i child panel */
+ "}");
So that the first panel will be in rendered in the first row and the rest of
panels will be disabled and etc.
It works fine, but i need a better solution. The jstl way works also, but all
panels will be displayed in each row of sheet.
I didn't think about a new implementation of the UIPanel, i will try this one
now.
Thank you
Regards,
Hani

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
