CompoundPropertyModel: override method or catch exception
To go with my other thread
<http://apache-wicket.1842946.n4.nabble.com/TextField-AjaxEventBehavior-onBlur-onEvent-tp4671150.html>
about the same form page, I have an issue with the CompoundPropertyModel.
There is a TextField in a form on this page, and the corresponding setter in
the model can throw an exception. When it does, wicket crashes the page. It
seems that it's using reflection by grabbing the name of the component on
the page, and looking for a setter for that component in the model
automatically behind the scenes.
What I need to have happen is either I can somehow override that method
through the CompoundPropertyModel, or just catch exceptions from the model
in general, or maybe some other mechanism. In any case, what I need is to be
able to cleanly reset things on the page in the case of an exception rather
than the page crashing altogether.

Hi,
Then you need to roll your own IModel and use it instead of
CompountPropertyModel.
**PropertyModel classes use reflection to find and call the setter and
getter methods.
