Hi,
The transient object in LoginUserModel is null because it was set to
null in LoadableDetachableModel.detach(). You need to reload it in the
LoadableDetachableModel.load() method.
For form submit examples, see
http://www.wicket-library.com/wicket-examples/forminput/
I think the answer is yes to your last question, but I'm not sure I
understand it.

Here is the hierarchy
Parent WebPage contains Panel. Webpage has a form
add(this.form = new Form("form", new CompoundPropertyModel<LoginUser>(new
LoginUserModel(user))) {
@Override protected void onSubmit() { .....
Now on webpage form submit, in the Panel I need to get the updated LoginUser
from form updates. I tried to pass LoginUserModel (which is
LoadableDetachableModel) to the panel constructor, the transient object
<LoginUser> is there during Panel initialization, *however on submit when in
the Panel, the transientobject is null in LoginUserModel* why is it null? I
have passed to the Panel constructor like PagePanel(...., final
IModel<LoginUser> smodel).
Also there are memeber fields which represents propertyfields like :
private String email;
this.form.add(dataContainer = new WebMarkupContainer("dataContainer"));
dataContainer.add(new DropDownChoice<Data>("data", Data.selectAll(), new
ChoiceRenderer<Data>("name", "id")).setNullValid(true));
would the updated value of dropdown be also available in Panel as part of
Model being passed to constructor. Please provide directions/examples.
Thanks in advance
