      JavaFX 2.1 b19, Win 7

      Description

      I just updated to JavaFX 2.1 b19 and noticed that double click in my TreeCells doesn't work anymore.

      It used to work in prior versions (last version I had was b13).

      As this is quite important for us, is it possible to get fixed for 2.1 GA ?

      EDIT:
      After some deeper investigation, I figured out, the problem only occurs, when the TreeView is within a Tab control. My first thought, was that maybe the Tab control consumes some mouseevents, but double clicking on a TextField still works within a tab.

      Here is some sample code. Double-click the TreeItem ("String1") with left mouse key. No output. Double-click it with right mouse key: output!
      Put the treeview out of the tab and as a direct child of root: Double-clicking works again for both mouse keys.

      If you can't fix it for 2.1, is there a workaround?

          public static void main(String[] args) {
              launch(args);

              VBox root = new VBox();

              TreeItem<String> rootTreeItem = new TreeItem<String>();
              TreeView<String> treeView = new TreeView<String>(rootTreeItem);
              treeView.setRoot(rootTreeItem);

              treeView.setShowRoot(false);

                              if (mouseEvent.getClickCount() == 2) {
                                  System.out.println("Double clicked");
                              }
                          }
                      });
                      return treeCell;
                  }
              });


              TabPane tabPane = new TabPane();

              Tab tab = new Tab();
              tab.setText("Tab1");
              tab.setContent(treeView);
              tabPane.getTabs().add(tab);

              root.getChildren().addAll(tabPane);
              Scene scene = new Scene(root);
              stage.setScene(scene);
              stage.show();
          }
