Error on creation of web experiment with duplicate title #12

Closed ctreffe closed 3 years ago

When creating a new web experiment with a title that has already been given to another web experiment an unhandled exception occurs:

This exception should be handled or prevented by a previous check for duplicate web experiment titles.

I'm not able to reproduce this bug - on my trials, the event is handled correctly with a display of a message informing the user about the duplicate title (see picture).
