Summary0003941: Draft WB Label bugs with Python 3
DescriptionDraft Label

some display issues,
  • a "b" and inverted commas sounding the otherwise correct values
  • displayed values not cleared when property changed unless it is over written
  • an error message when "area" is selected when a label is attached to a solid
Steps To ReproduceDraft Label

1) I get a "b" before the value and the value within single inverted commas. For example, something like this b'1000.00mm'.

2) if I select a solid and then attach a Draft Label to it, the default in the dialogue is volume, if I change that to area I get an error

Pick text position:
Traceback (most recent call last):
  File "/usr/share/freecad/Mod/Draft/", line 6407, in execute
    if "Face" in obj.Target[1][0]:
<class 'IndexError'>: list index out of range
Traceback (most recent call last):
  File "/usr/share/freecad/Mod/Draft/", line 6407, in execute
    if "Face" in obj.Target[1][0]:
<class 'IndexError'>: list index out of range

3) similar to 2) if you create the label with default "Volume" then after creation toggle the property to area in the property editor, you get the same error message above however it does actually correctly show the area despite the error message.

4)after creating a label, if you change the thing to display to something with nil value, it does not clear the previous values. Similarly if you select "Position" three values are shown, if you then select something with one value e.g. volume, it will display that Volume where X used to be but still leave Y and Z values from the previous use of "position".

I fixed the two first issues (the "b" and the error), but not really sure how to cope with the problem of the value suddenly becoming null. Shoudl the label display something like <NULL VALUE>? or ### a la excel... Most other features in FreeCAD don't do that, they just don't update the shape, and mark the object as problematic in the tree. Maybe we should do that? But it might be a bit too much, not sure...

(BTW I'm trying to fix the github->mantis integration too... Almost working)
