doc switching, a way to crash things about ghpython HOT 6 CLOSED

from scriptcontext import doc

Is not a good thing to do in a separate module. Modules in python are loaded and executed once. This means that the doc variable will point to the correct doc the first time the module is run, but may be pointing to an incorrect doc when the module is run in the future. I would recommend always calling scriptcontext.doc instead.

Thanks Steve.

also, I probably could have avoided this by calling RhinoDoc.ActiveDoc instead of scriptcontext.doc in my separate modules.

I would avoid RhinoDoc.ActiveDoc if possible and always use scriptcontext.doc. Mac Rhino is a multi-doc application and the ActiveDoc can switch.

Thanks Steve! will keep that in mind.

Variable assignment (document switching) is something that should not be sticky between sessions in any way. Also, I just tried the steps described above now and nothing happens, so a first guess would be that the crash depends later from additional side effects in the script... it might be in different places.

Did you manage to isolate the provoking part in the script? If not, can you check if, after reducing the script to a minimum set of operations and restarting Rhino, the crash disappears?

before I could find the steps to recreate it, I tried another reinstall of grasshopper in order to resolve it. That worked. I can switch target docs again.

Now I'll see if I can break it again.
