Hi,
ok, you have a panelGrid in your jsp with component binding to your
managed-bean property 'panelGrid' ?
In your action-method schrittweiseKriteriumHinzufuegen() your are
creating a new instance of SuchkriterienTable.
I can't see wehre you add this instance to any parent component.
Note: child.setParent(parent) don't add a child to the parent!
Use, as you do it with your commandLinks,
parent.getChildren().add(child) instead.
If this is not the problem, than i have no idea, but if you create a
example i can have a look again.
Regards
Volker
