I have a DropDownChoice that should update some form fields when the user
selects an item. My selection-changed-listener code is along the lines of:

 form.modelChanging();

 T obj = model.getObject();
 obj.setFoo(newSelection.getFoo());
 obj.setBar(newSelection.getBar());

 form.modelChanged();
 form.clearInput();
 form.visitChildren();

The problem is that without clearInput() the form fields do not update,
while with clearInput they do update, but I loose any input also in fields
other than FOO and BAR. I need a way to update only FOO and BAR fields and
let other fields alone so that they keep their current user input.

Thanks in advance for your help.
