Hi I've created a control which essentially is a radio button and a listbox, where each click on the radio button populates the listbox with values.
I've done or rarther are trying to do this by using the wicket radiochoice and a wicket ListMultipleChoice. And are overiding the onSelectionChanged and the wantOnSelectionChangedNotifications, so that onSelectionChanged does what I want and wantOnSelectionChangedNotifications returns true. However now I get this error: [PoolThread-9] ERROR wicket.RequestCycle - Unexpected runtime exception [page = null] wicket.WicketRuntimeException: Attempt to access unknown interface IOnChangeListener And I am a little confussed on why I am getting this error since the RadioChoice already implements the interface so it should be known? Only other option is that the error conseals another error which is caused by something else? I have a similar control which has this functionality, instead of using a radiochoice onselectionchange it uses a button to make something similar. I'll be happy to send the code and log, or just give a more detailed explaination. -regards Nino
