I have read it - a few times over the last 3 years of using Wicket and
even bought the book ;)
It says
"To use a CompoundPropertyModel, simply set one as the model for a
container, such as a Form or a Page. Create the contained components with
no model of their own. Insure that the component identifier names match
the appropriate property names."
The AjaxSubmitLink is picking-up the parent forms compound property model
but only checking to see if the "mylink" property exists when onSubmit
calls getModelObject().
I would like to get the Forms model via getModelObject but because it
errors when called, I have to either set a false model on the
AjaxSubmitLink or get the model object outside of the onSubmit, assign it
to a final property and then use it in the onSubmit.
I'm happy to admit that I'm doing something wrong but I cannot see what it
is???
Thanks again,
Tim
