Hi,
I have an Anchor that onClick performs an RPC call to a servlet. Based on
the outcome I want to set the hRef of the Anchor, and then perform the open url
action of the Anchor.
BUT: how can I tell the anchor to wait for the Callback to finish before
trying to open the url?
@UiField
Anchor anchor;
@UiHandler("anchor")
void onClick(ClickEvent evt) {
MyService.performRPC(jsonDTO, new MessageCallBack());
//delay here until callback finised and has set the hRef of anchor
}
class MessageCallBack implements AsyncCallback<String> {
@Override
public void onSuccess(String result) {
// do some computations based on the result and create the
url thereby
String url =...
anchor.setHref(url);
}
}
