I have been trying to add a Tooltip and a ContextMenu to a TreeTableView. I was able to add those easily to a TextBox but when I tried to do the same to a TreeTableView I was unable to drop either ContextMenu or Tooltip on the control in the hierarchy pane.

I edited the FXML on a text editor and once I re-opened it on scene builder I could manipulate them fine under the TreeTableView but I couldn't get them on the TreeTableView without manually editing the code.

I am attaching the "impossible" FXML. You can't create this FXML in scene builder.
