ClassCastException in PopupMenuService [message #1239496]

Hi,

When using the PopupMenuService to register a ContextMenu on a TreeCell, I get the following ClassCastException :

org.eclipse.fx.ui.workbench.renderers.fx.DefPopupMenuRenderer$ContextMenuImpl cannot be cast to javafx.scene.control.ContextMenu
at org.eclipse.fx.ui.workbench.renderers.fx.services.PartPopupMenuServiceImpl.registerMenu(PartPopupMenuServiceImpl.java:44)

I guess the problem is due to to the following line (44) in PartPopupMenuServiceImpl.registerMenu() :

return (ContextMenu) menu.getWidget();

which should instead be :

return (ContextMenu)((WPopupMenu<ContextMenu>) menu.getWidget()).getWidget();

Can one confirm this is a bug ?

Yes this looks wrong - unfortunately it is to late for 0.9.0 which has
already been released - if you need this you'll have to get the sources
from git and patch it locally!

Please file a bug so that we can fix it in 1.0.0.
