The panel is part of the form, but only needs to access one property
of MyModel. The rest is handled by other components of the form. The
compoundPropertyModel is passed through like this:
MyForm form = new MyForm("form", <CompoundPropertyModel>);
Then within MyForm, the panel is added. I also want to reuse the panel
for multiple properties of different Models, so it shouldn't depend on
the property name ("text" in this case).
In MyForm I changed
add(new MyPanel("textPanel", new PropertyModel(this.getModelObject(), "text"))
into
add(new MyPanel("textPanel", new PropertyModel(this.getModel(), "text"))
which works.
thanks,
Pieter
