GWT - Update Widget when java.util.List changes
Hello, I am new here and I came to seek for advices from more experienced GWT programmers. Here is my problem: I am making AsyncCalls and they fill some collections (java.util.List) with data. These callbacks take quite a time, so by the time collections are filled, UI is fully loaded. However, widgets that are supposed to show data don't show anything. Because when they were initialized, collections were still empty. Now I need to force my collection to somehow tell my widget 'hey I have that data for you, feed yourself!', but I don't know how. I was thinking of some observer pattern, but I am not really sure. How can I solve this issue? An example would be nice! -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Did you have a chance to go through this tutorial? http://code.google.com/webtoolkit/doc/latest/tutorial/gettingstarted.html When you get the data, you need to populate the widgets as shown here: http://code.google.com/webtoolkit/doc/latest/tutorial/RPC.html#invoke -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hello, yes. I quite misunderstood basic principles, I asked on Stackoverflow and issue was fairly easy.
