Hi, thanks Volker, adding the Components the right way made the Links work.
But! Now I run into another problem: As soon as I add the second Component I get the following exeption: javax.faces.FacesException: Client-id : sucheRoot_1 is duplicated in the faces tree. "suchRoot" is the id I specified for the surrounding tag on the jsp. But I explicitly set the id of all components I am adding. So where does this _1 come from. Could this come from some Id generated in Javascript for the CommandLinks?? Does anyone know at what point MyFaces generates Id's with "_1"? Any suggestion appreciated.

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.
