Short description of error
When using the wheigt painting tools on imported models the behavior is wrong/broken, if you set the skeleton into pose mode you are unable to select the mesh, to set it into wheight paint mode, preventing you from wheight painting the model or tweaking wheigts. I tried several other FBX and Collada files and all have the same problem.
Exact steps for others to reproduce the error
Open the provided FBX and import it.
Set the armature to pose mode and try selecting the mesh in the viewport.
