Did you ensure that you
1) set all the Ids of your programmatically created components
2) have a setPanelGrid (used for the binding after page reload i think,
i have never used the binding attribute however, my experience is
limited to composite components)
3) set all required properties for corresponding tags (that is if tag
for component X requires property y, ensure there is a setValue(Y,...)
in your code)
4) it still fails with only 1 binding, and no nested panelGrid.
