path WB: regression in FC 0.19

[uwestoehr]

The path WB does no longer work properly in FC 0.19. I cannot create even a simple pocket.
To reproduce:

1. open this example file:

Path-test.FCStd

test file

(22.89 KiB) Downloaded 35 times

2. Create a path job (use the proposed default settings)

result: After the final press on OK to get the job created, nothing happens, but I get in the report widget these errors:

Code: Select all

PathJobGui.ERROR: 'PySide2.QtWidgets.QDialog' object has no attribute 'widget'
Traceback (most recent call last):
  File "D:\FreeCAD-build\Mod\Path\PathScripts\PathJobGui.py", line 1315, in Create
    obj.ViewObject.Proxy.editObject(obj.Stock)
  File "D:\FreeCAD-build\Mod\Path\PathScripts\PathJobGui.py", line 195, in editObject
    return self.openTaskPanel('Stock')
  File "D:\FreeCAD-build\Mod\Path\PathScripts\PathJobGui.py", line 174, in openTaskPanel
    self.taskPanel = TaskPanel(self.vobj, self.deleteObjectsOnReject())
  File "D:\FreeCAD-build\Mod\Path\PathScripts\PathJobGui.py", line 567, in __init__
    self.template = PathJobDlg.JobTemplateExport(self.obj, self.form.jobBox.widget(1))
AttributeError: 'PySide2.QtWidgets.QDialog' object has no attribute 'widget'

3. retry to setup a path job. Now you it works.
4. Create a path pocket (choose a pocket of your choice)
(This is what I have now:

Path-test-pocket-result.FCStd

result after step 4

(35.58 KiB) Downloaded 32 times

)
5. Post process the whole job

result:

With FC 0.18.3 I get no problems at all.

It still works with the version below. Can you try to reset your settings?

I did so but the problem persists. As you cannot reproduce it with rev 0.19.18589 The issue must have been introduced recently between this revision and rev 0.19.18638.

This is not true, because when trying with

only the first error is gone, the second error - when postprocessing the job - is there as well.

I'll now try a Conda build and report back.

works for - certainly no help for you though. Given the error you're getting it sounds more like PySide / Qt issue. Maybe our build experts have some insight.

The 0.19.18234 build is one I downloaded from GitHub , the 0.19.18638 build was built by myself. Both used the LibPack available in the 0.19 release on GitHub.
I cannot test a Conda build because all downloads from GitHub are today super slow and sooner or later terminated. (Seems amazonaws.com has problems.)

However, the error

Code: Select all

  return self.script.export(obj, filename, args)
  File "D:/FreeCAD-build/Mod/Path/PathScripts//post\centroid_post.py", line 170, in export
    if isinstance(item.Proxy, PathScripts.PathToolController.ToolController):

'_TempObject' object has no attribute 'Proxy'

sounds strange. Note also the wrong double slashes in the path:
D:/FreeCAD-build/Mod/Path/PathScripts//post\centroid_post.py

Double slashes are typically not an issue and it seems the python interpreter can find your file - so even the backslash seems to be OK. I have no idea what a _TempObject is and what it's doing there though.

I can retry when the new MacOS version is out.

I get the same error. But I see now that it is related to the output processor. I use the default "centroid". When using e.g. "grbl", I get no error and a correct output.

I investigated a bit and I encountered this:

all other postprocessors work.

[chrisb]

I will wait for the new version and check (at least the philips post processor).
