What is the justification for JavaFX FXML schema not supporting context menu inside the panes?

Question

It is possible to add a context menu to a scroll pane, but not to other types of panes. Why?

Answer 1

Described method to open popup leads to multiple popups open if every node in the scene graph want to open context menu. Consuming of event is definitely needed.

See also discussion at Using FXML to Create ContextMenu within a Pane It provides working answer to this problem.

BTW, Node.onContextMenuRequested(...) should be used instead, yes?
