title: GWT MVP Presenter Unable to Update View Listbox Component
body: <p>I am writing a GWT MVP application using the gwt-platform library (very nice once you get used to it). My issue occurs when my presenter attempts to update the contents of a Listbox. The problem occurs on line 66 of the below file:</p>
  
  <p><a href="https://github.com/dartmanx/mapmaker2/blob/master/src/main/java/org/jason/mapmaker/client/presenter/MapmakerStackPanelPresenter2.java" rel="nofollow">https://github.com/dartmanx/mapmaker2/blob/master/src/main/java/org/jason/mapmaker/client/presenter/MapmakerStackPanelPresenter2.java</a></p>
  
  <p>I am sure that the application is calling the onSuccess() method (a breakpoint in the debugger works), and that the result is populated.</p>
  
  <p>One thing I've noticed is that the associated view, MapmakerStackPanelViewImpl2.java, seems to be initialized twice. I find myself wondering if I'm trying to update a control on that view that is not attached to the actual user interface. That file is here:</p>

  <p>Any help would be appreciated.</p>
