Summary:
changes to pose bone selection state via python have no effect.

Detailed description

see attached file with simplified example.

Basically setting bpy.context.active_object.pose.bones['Bone'].select=True or False has no effect. Maybe this part of context is meant to be read only and return an error? If so is there a correct way to set selection state without using ops?

Thanks,
Josh

I think what you're seeing, is that the context.selected_pose_bones list always includes the "active" bone too. Hence, even if you manage to unselect the bones, you can't make it non-active.

Assigning to Campbell for final verification on whether there are any other alternatives via py...

Hey Aligorith,

The script tries to deselect all the selected bones, not just the active bone - I should have said in my instructions select 'more than one' not one or more... thanks for pointing that out.

However just double checking... with objects bpy.context.selected_objects does not contain the active object if it is not selected so I'm not sure whether this should be the case with bones?

Thanks,
Josh

Hey Aligorith,

Could we have Active & Selection be disconnected, just like with object & mesh mode?
IMHO the way it is now is inconsistent and confusing for the developer and the user.

The check for POSE_OT_select_all toggle is incorrect at the moment, but I think including an unselected bone in the selected list is just asking for problems.

Example of how it fails:
- Add Bone
- Enter Posebone
- Akey to toggle selection (Nothing happens)

While this can be fixed, Id prefer to make selection work like the rest of blender.

Hi Again Aligorith,
My original intention with adding active bone was that it should behave the same as objects, looking over the code I think this is best.

Will commit in a bit.

remove pose_bone.select this is only ever used on read/write, use pose_bone.bone.select now.
