[Pharo-users] Spec on Moose 6.0 error: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray
