Hi,

I have a TabPanel which has multiple items. On every TabItem there are some fields. I have written a FormButtonBinding class, which monitors all the TabItems (which contain FormPanels). The monitoring class uses FormPanel.isValid() which calls on every field Field.isValid(). Here is a call of Field.getRawValue() which will only work if the field has been rendered. How I can force an attach/rendering for the hidden panels?

Thanks
Andre
