Hi Igor,
Thank you for a quick response.
I get your point. My main page should have client object and model that
is referring this object and I should use the same model in
DropDownChoice, Form and Panels for TabbedPanel.
The problem is I have too many clients in my DB to pull them out at the
start up of the page. Other thing is that client object is quite big.
That's why in my DropDownChoice I have only list of clients' names and
I'm pulling out the client from a DB when the specific client is
selected.
I haven't specified that in my previous email, but client has list of
objects (accounts, contacts) that are used to populate DropDownChoices
in other tabs. So I have first tab: Profile with general info, and two
other tabs Contacts, Accounts with DropDownChoices from which you can
choose which contact/account to display on the tab form.
Best regards,
Dariusz Holda

Subject: Re: [Wicket-user] Problems with updating TabbedPanel
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.
