NullReferenceException when maximizing canvas window.

[sonbParticipant]

Hi.

After I maximize and restore the Canvas window by pressing SHIFT+SPACE or using window menu I get the following error:

1 2 3 4 5 6 7 8 9 10 11 12

NullReferenceException: Object reference not set to an instance of an object NodeCanvas.Editor.GraphEditor.get_targetOwner () (at Assets/Additional Packages/ParadoxNotion/FlowCanvas/Framework/Design/Editor/Windows/GraphEditor.cs:94) NodeCanvas.Editor.GraphEditor.OnGUI () (at Assets/Additional Packages/ParadoxNotion/FlowCanvas/Framework/Design/Editor/Windows/GraphEditor.cs:406) System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:222) Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.

The error keeps spamming until I close the Canvas window, which became unresponsive and empty.

Hi SONB

I have attached an image for what i did to solve it (GraphEditor.cs).
Please, try to add those lines in red outlined rectangle, it worked for me.

I hope it helps…
