[4.3-beta]Splitting a bone that is included in any skin prevents the project from being saved #949
Description
Description:
Splitting a bone that is included in any skin results in the following error and prevents the Spine project from being saved:
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Bone is not in skeleton: [bone]
ERROR: Unable to save project: /Users/Desktop/skin-bone.spine
Errors prevent the project from being saved.
Expanding the skin in the Tree view in this state reveals an unusual condition in which the split bones appear duplicated for unknown reasons. In the example below, the skeleton contains only four bones in addition to the root bone, yet the skin lists 13 bones:
Expected behavior:
Splitting should work correctly even when a bone belongs to a skin, and the Spine project file should be saved without issues afterward.
Steps to reproduce:
- Create a new project in 4.3.39-beta.
- Create a skin.
- Create a bone with a length and add it to the skin created in step 2.
- Click the
Splitbutton and split the bone. (The values for options such as the number of resulting bones do not affect the outcome.) - Attempt to save the project. An “Error saving project” dialog will appear, and the save operation will fail.
