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.
