PD_Gear_ViewProviderPythonFeature is not JSON serializable

[jriegel]

I did the icon. Its basically a placeholder. I'm particularly bad with icons

I have a similar problem

Code: Select all

def createManager(name='My_Manager'):
	obj = FreeCAD.ActiveDocument.addObject("App::DocumentObjectGroupPython",name)
	obj.addProperty("App::PropertyInteger","intervall","params",
						"intervall")

	obj.addProperty("App::PropertyPythonObject","run","zzz",	"run")
	obj.addProperty("App::PropertyLinkList","targets","zzz",	"targets")
	obj.addProperty("App::PropertyString","text","params",		"text")
	_Manager(obj)
	_ViewProviderManager(obj.ViewObject)
	return obj

when I save the file I get

raceback (most recent call last):
File "/usr/lib/python2.7/json/__init__.py", line 243, in dumps
return _default_encoder.encode(obj)
File "/usr/lib/python2.7/json/encoder.py", line 207, in encode
chunks = self.iterencode(o, _one_shot=True)
File "/usr/lib/python2.7/json/encoder.py", line 270, in iterencode
return _iterencode(o, 0)
File "/usr/lib/python2.7/json/encoder.py", line 184, in default
raise TypeError(repr(o) + " is not JSON serializable")
<type 'exceptions.TypeError'>: <group object> is not JSON serializable

after reopen

Traceback (most recent call last):
File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")
<type 'exceptions.ValueError'>: No JSON object could be decoded
<unknown exception traceback><type 'exceptions.AttributeError'>: 'module' object has no attribute 'instancemethod'

second file save without errors
second reopen

<unknown exception traceback><type 'exceptions.AttributeError'>: 'module' object has no attribute 'instancemethod'

The connection of the proxis to my group objects are lost
At the moment I use the workaround after reload

Code: Select all

for ob in FreeCAD.ActiveDocument.Objects:
	if hasattr(ob,'Proxy'):
		ob.Proxy.__init__(ob)
		print("init " +ob.Name)

But the question is
Is it an error of me
or
is it caused by the non serializebility of group object
and can be fixed ??

thanks in advance

A completely unrelated problem:
The gear generator icon is grey on grey (the ubuntu menu's background is grey), so completely unnoticable, until you hover the mouse on the menuitem.

Who designed the icon? Can he/she add a white around the gear icon, so it would be noticable?

Don't know but we are aware of this issue. Jim recently offered some alternatives but AFAIR there was still no decision which one to use. @Jim, is there a preferred icon we should use?

I think the icon has since been updated; for me it looks like this (only not 64 x 64 pixels), and has for a while now:
