How can i use Apache Wicket to process multiple model instances on a single form?
arrays,hibernate,model-view-controller,wicket

Show correct model value even if error on field
When validation fails on a FormComponent, its rawInput isn't cleared - this is so that the user can fix the value, rather than having to enter everything from scratch. In your case you are basically changing the model behind the FormComponent's back so it doesn't know there is a new...

What is the Difference between returning IModel and IModel?
There are no other differences. The difference lies purely in the syntax. With IModel<?>, the casting has to be done explicitly (as you noted). However, by using generics, you tell the compiler to cast it to Bar when returning from the getObject() method, so you don't have to cast it...

How to setHeader in ResourceStreamRequestHandler#configure(..) (migration issue)
java,wicket,wicket-1.5,wicket-6

Change DropDownChoice to ListView in Wicket
java,listview,wicket,dropdownchoice
I'm still a bit confused about what you are trying to achieve here, but I'll take a stab in the dark. If I understand correctly, you want to move away from DropDownChoice, as it has to be applied to a <select> tag, and change it into a ListView, as it...
Wicket, How can a DropDownChoice select change the options of another DropDownChoice?
You should use the value of the first choice to determine the value of the second one.

Start CDI Asynchronous bean and update Wicket UI with WebSockets
java,asynchronous,websocket,wicket,cdi
Looks like http://wicket.apache.org/guide/guide/nativewebsockets.html#nativewebsockets_6 (the FAQ). WebSocket communication is not intercepted by Servlet Filters so DI frameworks like CDI, Spring and Guice have no chance to prepare their scoped beans. In your case RequestScoped. You can use only application and prototype scoped beans.
Wicket, specify default contents of child element in basepage
You should use composition instead of inheritance for such use cases. I.e. use a Panel that is created by a (protected) factory method. The child page should override this method and create a different Panel.
