I did see that "toString(): failed" when saving doc. I dont know that it broke but looks saving works. Can you fix that error?

I'm still not familiar with FreeCAD plugin dev, I need to learn why use FeaturePython, then can give a solution for that.

I have no clue to debug it. It seems set a property to JointProxy or ViewProviderDocumentObject with TypeError, but I don't know which is.

This JSON serialization is something new and I still need to figure out how to solve it. Help welcome!

drfenixion commented 5 months ago

@galou Looks like it is related to https://forum.freecad.org/viewtopic.php?t=84305 and can be solve by change FC version to 0.21.1 or latest_dev_build or 0.21.3 (in future).

galou commented 5 months ago

User of FreeCAD <= 0.21.1 should use https://github.com/galou/freecad.cross/releases/tag/fc_v0.21.1.

A few more commits may be compatible but I'm going to remove the __setstate__ and __getstate__ functions.
