Re: [udig-devel] PlatformGIS functions do not work

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

I am extremely confused as to why that snippet doesn't work because I 
have used it a number of times and I know that it works...

I have just used this code try it and see if it works.  If not then 
there is something wrong with your environment... :(

       try{
          
           //For some reason, getting the active workbench doesn't seem 
to work??!! So looping
           // through all the workbenches and all their pages was the 
slow way to go...
           //IEditorReference[] editors = 
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getEditorReferences();
           IWorkbenchWindow[] wWindows = 
PlatformUI.getWorkbench().getWorkbenchWindows();

           List<IMap> maps = new ArrayList<IMap>();
           for ( IWorkbenchWindow wWindow : wWindows ) {
               IWorkbenchPage[] wPages = wWindow.getPages();
               for ( IWorkbenchPage wPage : wPages ) {
                   IEditorReference[] editors = 
wPage.getEditorReferences();
                   for ( IEditorReference editor : editors ) {
                       IEditorPart editor2 = editor.getEditor(false);
                       if( editor2 instanceof MapEditor ){
                           maps.add(((MapEditor)editor2).getMap());
                       }
                   }
               }
           }
           if (maps.size() == 0)
               return null;
           return maps;
       }catch(NullPointerException e){
           return null;
       }
