I for one can't follow your example but sounds to me that you are setting your model on the form and are using collections.
First use-case like that which comes to my mind is a list of selected radio and check boxes or multiple selections in a select box. Using Wicket you shouldn't have to work too hard on updating the model object (be it a collection) to update it with the user input. Wicket should do that for you and if it's not working you might be doing something wrong or forgetting something else. I would suggest to take a look at how CollectionModel is used: http://www.wicket-library.com/wicket-examples/compref/wicket/bookmarkable/or g.apache.wicket.examples.compref.PalettePage?0 Perhaps that can aid answering your quest. Otherwise, please better phrase your question and/or submit some code examples to help us better understand. ~ Thank you, Paul Bors -----Original Message----- From: Nick Pratt [mailto:nbpr...@gmail.com] Sent: Monday, December 10, 2012 1:11 PM To: users@wicket.apache.org Subject: Form submit with Collection<Child> My understanding of Form submit behavior with models is that onSubmit, Wicket loads the model, and then applies all the changed form values to that model. This works fine for non-collection types (Strings, ints etc) set from all the input types Ive been using (TextField, RadioChoice, DDC etc.). However, what is not working is the addition of new Entities that live inside a Collection of the IModel entity. Lets say I have a 1..N relationship, A..B, and I want to add 2 new Bs to A's collection (a fairly common requirement) in my form. I dont want these new B entities persisted in the DB until the entire form is submitted (Im using JPA cascade). How do I code this part of the form/logic so that when I hit submit, I get those 2 new B entities added to the A.b collection, so that I can save(a) and have everything update?
