And when do you want to block exactly? When a certain Ajax action is
executed, which may take some time to complete? And you would do some
Ajax polling to track the progress?
The easiest way in that case would be to re-render the form with the
form components disabled, and when the polling concludes that
processing is done, re-render the form again with the form components
enabled again. You could add two methods on your form: disable/
enable. Something like:
public void disable() {
visitChildren(FormComponent.class, new IVisitor(){
public Object component(Component component)
{
component.setEnabled(false);
return IVisitor.CONTINUE_TRAVERSAL;
}});
}'
Whenever you build this form, you should check the job's state too, so
that if you have a background job running, your form has the proper
mode wherever you come from. And if there is a job running, make sure
you have that ajax polling thing going until the job is finished.
Just something from the top of my head, hope it helps,
