nope that's not true, they don't expect Strings
correct me if i'm wrong, but i think the problem most likely lies here:
add(new DropDownChoice("ddArtikel", new PropertyModel(artikel, "name"),
artikelList, new ChoiceRenderer("name", "id")));
--> the choicerenderer looks for the path "id" on the model object, which is
a string in your case (new PropertyModel(artikel, "name")), use e.g. new
Model(artikel)
