Validation Error: Listener XXXX already exists

I’m starting to develop on a project and clone our repository.

Now, checking the code, I tried to see an Entity Listener, and when I “Edit” it, and press Source, I get this error.
If I press IDE it opens correctly on IDEA, but don’t know how to stop getting this error from Cuba Studio (web version 6.9)


This error message means that there already exists a class with the name “EmpleadoEntityListener” in that package. Have you modified the “Class name” property before switching to the “source” tab?

Which Version Control System do you use? I have tried to reproduce the problem in my project (cloned from GitHub) but everything works well.

Which version of CUBA Studio do you use?
