| Summary | 0000598: New version treats some objects as immutable | ||||
| Description | I'm getting the following error after upgrading to a new version (tested freecad-daily and a self compiled version from git). File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/rule_application.py", line 341, in applyRule "RHS-Object '%s' collides with an object in the CWS. Retracting!\n") File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 168, in collisionManyMany2 return do_calc(lambda x: collisionOneOne(x, check_union)) File "/usr/lib/python2.6/contextlib.py", line 34, in __exit__ self.gen.throw(type, value, traceback) File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 63, in union yield shapes[0] File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 168, in collisionManyMany2 return do_calc(lambda x: collisionOneOne(x, check_union)) File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 157, in do_calc if coll_fun(cws_o): File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 168, in <lambda> return do_calc(lambda x: collisionOneOne(x, check_union)) File "/home/marc/FreeCAD/Mod/spapper/spapperlibs/collision.py", line 87, in collisionOneOne return one.Shape.common(other.Shape).Vertexes != [] ReferenceError: This object is immutable, you can not set any attribute or call a non const method This bug was introduced in the last couple of weeks, because freecad-dev (0.13R4972) does not have this error. The extra module in use is spapper (https://sourceforge.net/projects/spapper/) but it shouldn't be related to this issue. | ||||

Can you give me a short introduction how to use this module, please? Whatever I do I got some python errors or a message box pops up. Indeed there were recently made some changes which fixed the 'Const' attribute in some of our XML descriptions for the Python wrapper classes. So, it was wrong in version 0.13R4972 and before and works now correctly. But apparently this caused some collateral damages to third party module which must be fixed there. So, if you can give me some overview of how to use the module I can create a patch and send it to the project maintainer. |

I uploaded an example, here are the instructions: 1. open FreeCAD file 2. switch to spapper workbench 3. load rule (2. toolbar button to the right) 4. enable collision detection (checkbox in the spapper view) 5. apply rule (right toolbar button) Now there is the error in the report view. Thank you very much for your effort. Please send me the patch as well. |

I found that there were still a few missing Const attributes from some functions. This means that 3rd party code doesn't need to be patched. It's fixed in SVN 5434 and will be available on PPA very soon. |
