you are not using the models properly
instead of pushing selected objects into models for a lot of components
simply write those components to pull the value from a single place
the workflow is then:
dropdownchoice pushes selected client into a page property
form pulls selected client from that propery
profilepael inside tabbedpanel pulls that client from that property
class mypage extends webpage {
private Client client;
mypage() {
final IModel clientModel=new PropertyModel(this, "client");
setmodel(model);
form f=new form("form");
f.add(new DropDownChoice("client", clientModel, ....) { onchange()
{//noop - model will do all the work} }
profiletab=new abstracttab(..) { getpanel() { return new
profilepanel("id", clientmodel); }
}
that represents all the linkages you need.

Hi,
I created TabbedPanel inside a form. The form has just one field which
is the name of the client. The TabbedPanel stores different information
about the client. At the top of the page I have DropDownChoice with the
list of clients. When the client is choose from the DropDownChoice I'm
changing the model object of the form and model object of the
tabbedpanel in the onSelectionChanged method. I can see the change in
the field on the form but to see the changes in the TabbedPanel I have
to click on a tab. The thing is I want to see the TabbedPanel with the
new info straight away after choosing the client. Can someone advice me
something.
