Hi All,
Is it possible to reuse the jface Wizard object?
I have to invoke the same wizards many places/ many
times in my application, So is it possible to use back the same instance
of the wizard in other places. Seems when I finish/Cancel my wizard, it's
internally disposing it's pages & container so i have to re-create a new
instance.
see my sample usage below:
OpenProjectWizard wiz = new OpenProjectWizard();
wiz.init(site.getWorkbenchWindow().getWorkbench(), null);
WizardDialog dialog = new WizardDialog(shell, wiz);
dialog.open(); // Invoke First time
// get values
dialog.open(); // Invoke Second time
// get values
dialog.open(); // Invoke third time
// get values
what happened is, when I invoked the second/ third time the wizard
did got invoked but ALL the operations disabled except CANCEL.
is this the normal behaviour?
thanks for any help.
thanks
Albert

JFace Wizards need to be recreated every time, as I know by having tried
what you did and gotten unpleasant results. I believe I saw the same
thing said in the docs, but don't recallwhere just now.
