The preselect handler works great unless I set the selection filter to occurrences. When I do this I get an error:
There is not an isVisible property for an adsk.fusion.component and when I hover over anything in the tree or screen that is not an occurrence or body I get this error. Seems to be anything at the root component level, like a plane, etc. I have included code below that will throw the error. I've tried putting in if statements in the handler to try and correct this with no success. As soon as it enters the handler it throws the error. Any help here would be greatly appreciated. This will work for me if I can get it to work.
