When there is a plugin installed using the dockable part there is a sequence that is giving the error “Key already exists Parmater name Key”. The error message is below. When we are in debug mode we can see that this message is appearing before entering the function of the plugin.

The sequence to reproduce the bug when there is a plugin using the dockable part of the api

- Is to have 1 project open (project A)
- Enter into file view of project A
- Open a new project (project B)
- remove project A from the list
- Enter in file view mode of project B
- Review file of project B

Is it possible to correct or find a bypass to this bug?

The error:
