Environment: Firefox 3.6.13/IE 8.0.7600 on Win7

The bug occurs only using RAP 1.4 M5. With 1.4 M4 it works correctly.


Steps to reproduce:
* create a tree viewer
* add a IDoubleClickListener to the tree viewer
* add drag support to the tree viewer
* fill it with some items
* double-click on any (not selected) item
-> The IDoubleClickListener is called as expected
* select one item
* double-click on the selected item
-> The IDoubleClickListener is not called

Expected:
The IDoubleClickListener is called on every double-click.


Here is a snippet to reproduce:

public class Snippet implements IEntryPoint {

    public int createUI() {
        Display display = new Display();
        Shell shell = new Shell(display, SWT.TITLE);
        createContent(shell);
        shell.layout();
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        return 0;
    }

    private void createContent(Shell shell) {
  		shell.setLayout(new GridLayout(1, false));
  
  		Tree tree = new Tree(shell, SWT.NONE | SWT.MULTI);
  		tree.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
  		TreeViewer viewer = new TreeViewer(tree);
  		viewer.setLabelProvider(new LabelProvider());
  
  		viewer.setContentProvider(new ITreeContentProvider() {
  			public Object[] getElements(Object inputElement) {
  				return new Object[] {"Root"};
  			}
  			public Object[] getChildren(Object parentElement) {
  				if (hasChildren(parentElement)) {
  					String[] input = new String[10];
  					for (int i = 0; i < input.length; i++) {
  						input[i] = "Item " + i;
  					}
  					return input;
  				}
  				return new Object[0];
  			}
  			public boolean hasChildren(Object element) {
  				return element.toString().startsWith("Root");
  			}
  			public void dispose() {
  			}
  			public void inputChanged(Viewer viewer, Object oldInput, Object newInput) {
  			}
  			public Object getParent(Object element) {
  				return null;
  			}
  		});
  		
  		viewer.addDoubleClickListener(new IDoubleClickListener() {
  			public void doubleClick(DoubleClickEvent event) {
  				MessageDialog.openInformation(shell, "Test", "Doubleclicked");
  			}
  		});
  		
  		viewer.addDragSupport(DND.DROP_COPY | DND.DROP_MOVE | DND.DROP_LINK, new Transfer[] {TextTransfer.getInstance()}, new DragSourceAdapter());
  
  		viewer.setInput(new Object[0]);
  		viewer.expandAll();
    }
