The serializeable/transient explained the exceptions. That was easy to fix.
I have read the wiki entry on models (several times) but there is
obviously something I don't get.
I don't think that the difference between
this.getForm().get(ID_SPAN).setModelObject(mySelectedView);
and
this.getForm().get(ID_SPAN).setModel(new PropertyModel(mySelectedView,
ID_SPAN));
is "well explaind".
Thanks for your time - Johan and Christian - it's working now.

everything that is inside a Model as its model object
That is not detached (so not converted to a serializeable id or something
like that) must be serializeable of its own.
so youre DiffusionProcess must implement Serializeable
Or must be transient (then you must be able to recreate it from null)
Or must be converted to an id or something so that you can recreate it with
that information.

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.
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.
