Hi,
I have a simple form. When I submit it I launch a thread that runs on the
background. When the thread is finished, I would like to update a
DropdownChoice with the result generated by the thread. I manage to update
the choice, but the changes are only visible when I refresh the page. To
avoid that, I have used a AjaxEventBehavior to update the choice whenever
the user clicks on it:
serviceNameChoice = new DropDownChoice<String>("serviceNameChoice", new
Model<String>(),
serviceNames);
serviceNameChoice.add(new AjaxEventBehavior("onclick") {
protected void onEvent(AjaxRequestTarget target) {
target.add(serviceNameChoice);
}
});
The result is an unusable drop-down choice, since the choice keep refreshing
when I try to select a value.
How can I do what I want, that is, update/refresh a DropdownChoice when a
background thread finishes its work?
Thanks!
Humberto
