Hi, I was working on a new project and I added a search field to a toolbar. I decided against it and deleted the search field, however it was still visible in the design area. I then got the error "TypeError: 'null' is not an object".
Looking at the Project Inspector the line from MyNestedList2 instance to CategoryList is no longer joining them together, but shoots off the top of the screen...
Thanks for the test case, it's helped us isolate a bug in the drawing of the arrow linking.
The bug that is occurring is that channellist has been linked to two places. We are trying to link to a node which has not been created yet. In the interim if you expand out the "ChannelFilterViewTablet" view it will not cause this error.
