PropertyModel that add/read element from collection
Hi,
Is there a good way to add an element to a collection using a PropertyModel?
What I'd like to do is this:
..
form.add(new DefaultValueDropDownChoice("id, new PropertyModel(model,
"categories"), jobTypes));
..
This obviously doesn't work since "categories" is mapped to a java.util.Set.
/Johan

Well it doesn't work for me, but mabey I'm doing something wrong.
"categories" in my case is a set of Strings and the result/value selected
from the DropDownChoice is a String and not a Set. Wicket says that it
cannot find method "setCategories" which is reasonable because there's no
such method and even if there were that's not the method I'd like to call.
Add like to call the add method of the Set itself.

sure about that? did you try it?
I'm using the Palette component exactly that way (also backed with a Set)
and it just works
