Error message on Job deletion

[chrisb]

I have loaded the model from this post. When I try to delete the Job I get an error popup saying 'NoneType' object has no attribute 'Stock'.

I confirm with Ok and get in report view:

Code: Select all

Traceback (most recent call last):
  File "/Users/cb/Desktop/FreeCAD.app/Contents/Resources/Mod/Path/PathScripts/PathOp.py", line 291, in onChanged
    self.opOnChanged(obj, prop)
  File "/Users/cb/Desktop/FreeCAD.app/Contents/Resources/Mod/Path/PathScripts/PathAreaOp.py", line 156, in opOnChanged
    self.areaOpOnChanged(obj, prop)
  File "/Users/cb/Desktop/FreeCAD.app/Contents/Resources/Mod/Path/PathScripts/PathMillFace.py", line 83, in areaOpOnChanged
    obj.OpStartDepth = job.Stock.Shape.BoundBox.ZMax
<class 'AttributeError'>: 'NoneType' object has no attribute 'Stock'

If I try to delete the job again it is removed and I get another line in Report view

Code: Select all

PathOp.ERROR: No parent job found for operation.

After that Path workbench seems to be broken, I cannot select a body to create a new job

If I create a simple cube with a contour path everything works as expected.

Is my FreeCAD too old?
