Perhaps I'm missing something big time about BoundCompoundPropertyModel. I
removed my loadable detachable model and still can't get it to work
specifically with a dropdown element.
The following works...
FormComponent networks = new DropDownChoice("network", new
PropertyModel(phone, "network"), networksList);
but the following doesn't....
FormComponent networks = new DropDownChoice("network", new
BoundCompoundPropertyModel(phone), networksList);
I've tried stepping into the code but can't resolve the issue. Can anyone
confirm or explain this problem?
