Short description of error
When an addon uses a
CollectionProperty
to add data to things (example: bones), it uses[collection_path].add()
to add the container for the data.When the owner (bone/object/etc) of that parameter (CollectionProperty) is linked and a Library Override, Blender returns an error when trying to add to the collection.
Exact steps for others to reproduce the error
cube.blend cube-linked.blend
cube-linked.blend
Is the test file.cube.blend
is the file being linkedOpen
cube-linked
.Run the script on the left in the Text Editor
Copy the test code to the Python Console on the right
bpy.context.object.col.add()
The Torus object (not linked) will run as expected.
Select the cube (library override) and run the test code again
Blender will say
TypeError: bpy_prop_collection.add(): not supported for this collection

Changed status from 'Needs Triage' to: 'Archived'
For this to work, you have to flag the
CollectionProperty
withUSE_INSERTION
cube-linked-corrected.blend
It is a bit hidden, but not a bug. Will close (but feel free to comment again if issues persist)

Thank you.
I haven't tested yet but I'm sure it'll work.

With 'USE_INSERTION' you can add new items to the override collection prop, but if you save and reopen the file, the items are not saved.
You can try it with the addon "Selection Sets".
Is it a bug? Probaly is the correct way (you can override and modify the props, but not their structure... I think...)
