Change EventBinding Name
FORUM OP: Can you please move this into the Architect 2 bugs
TypeError: 'undefined' is not an object (evaluating 'this.opening.update')
Had a window in the view section of the inspector and I changed the deactivate to a blur.
Please not each of these event bindings were previously focus and blur then changed to activate and deactivate then switched around and then the original blur was changed back to blur after going from activate to deactivate.
If you can provide exact steps to reproduce we can get this fixed.
