I’ve recently been having an issue on our cobot that I haven’t seen before. I am making a relatively large program that calls smaller individual subprograms, but there are a few subprograms that are giving me some issues (both palletizing operations). When initially call the subprograms in they work as expected and everything runs fine but as soon as I save, close and reopen the program. both turn yellow and give me an error. They both say NullPointerException in the “At Each” part of the pallet. I’ve done some research into it, and it says it is a java error that happens when variables don’t get initialized. My best guess is that it has something to do with the pallet position reference point, but I can’t figure out why or where this is happening, any suggestions or help would be appreciated.
I’ll add you to the list of people I’ve seen report this. It’s been years and the issue hasn’t been fixed. With UR’s push for Polyscope X, I doubt you’ll see a solution to this.
