System Information
Operating system: Linux-5.19.0-41-generic-x86_64-with-glibc2.36 64 Bits, X11 UI
Graphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 530.41.03

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-05-13 23:11, hash: 018f3dbf8533

Short description of error
When gradient painting over a group, the auto normalization affects other groups that are locked.

Exact steps for others to reproduce the error
Weight Gradient Normalize.blend

  1. Notice the weighing of the Bone 1 vertex group.
    image
  2. Select the Bone 2 vertex group.
  3. Drag over the model to gradient paint.

  4. Select Bone 1 again.
    Bone 1 has been auto normalized even when it's locked

What is the expected behavior here? Should the entire operation be blocked if any vertex groups are locked?

The problem seems to be that you shouldn't change the other vertex groups, just the active ones?

That is correct. When a vgroup's values can not be changed due to normalization locking in other vgroups, the values simply don't change no matter how you try to paint them. Except the broken gradient 😌

I believe this is the same thing #107918 , overall lack of checking for locked groups. Likely due to attribute system change.
