Sorry. This is the error message:

Exception (Mon Jun 3 15:41:45 2019): Sketch::checkGeoId. GeoId index out range.

Ok I tested here, and I can't reproduce the issue...
I can make a wall, change its length, save the file, reopen the file, and still change the length.
Can you maybe attach a file where the length is not editable anymore after reopening?

Thanks Yorik.
Ok. I deleted all FreeCAD installations and I tested the last FC version. Same problem.

This is a strange bug. I found out that the points of a sketch cannot be moved programmatically if the sketch hasn't been in edit mode at least once in the session.

However, I could not succeed in doing a quick in-and-out of edit mode programmatically either, it makes FreeCAD crash. I guess entering and exiting sketches edit mode does a lot of additional operations, it's not meant to be triggered that way.

So ATM as a workaround in git commit 385771153 I just added a message to warn the user that they must enter and exit edit mode for the base sketch. I guess that's already something...
