Hi,
There are a couple of things I don't understand.
1) I have a form using a CompoundPropertyModel with a HashMap as the
initial model object. When I later (after having made a choice in a
DropDownChoice) call
this.getForm().setModelObject(aNewModelObject);
nothing in the gui is updated. Typically I have components declared like
tmpForm.add(new TextField(ID_SPAN));
that I'd like to have updated.
Component.setModelObject(Object obj) does call IModel.setObject(this,obj).
The CompountPropertyModel than takes the id of the component and
interprets it as a bean expression into the underlying Object (or in case
the the CoumpoundPropertyModel wraps another model the Object from the
wrapped model).
So in your case:
==>form.setModelObject(aNew)==>CompoundPropModel.setObject(form,aNew)==>map.put(form.getId(),aNew);
There are a few solutions (and others):
1.) keep the underlying map in an instance variable und access it (in case
you do not use
detachable things).
2.) use form.getModel().setObject(null,new Map())
2) In the same page I (sometimes) get an exception like the one below.
What requires the DiffusionProcess class to be serializable?
DiffusionProcess is used to do some calculations, and instances are
cached in objects used as model objects.
Generally if you do not provide a IModel (or subclass) which does not load
on each new Request a newly the underlying Object than the Object must be
serializable, because than the Object gets saved into the session.
Please read the wiki how-to entry. This and the above is well explaind
there.
