I'm currently rewriting an application from Stripes to Wicket in a
project here and have the following (simplified) problem.
I've got two list components that are filled from a model, and then I
use javascript to transfer items between them, but when the lists are
submitted no new values are added to the model.. Is this expected
behavior or am I missing something? Below are the code (javascript for
moving items and selecting all items before submitting are taken out)
Btw, if I select the first five items in the list and add them to the
other they are dublicated and in the submitted list, so it seems like
you only can submit existing items (with same id) to a list/model,
seems kind of strange to me...
thx,
Kjetil
