Bug impossible to delete a ressource or a participant from a

[michaeled]

A bug in version 4.0.87 : it is impossible to delete a ressource or a participant from an event already created in our calendar.

Moreover, it's impossible to edit anything on an event if you choose a resource : it displays the window of ressource conflict. If you uncheck the checkbox of the corresponding ressource, you can validate the modifications, but the ressource is still reserved.

This bug continues to exist in 4.0.89 and goes back as far as 4.0.77

I can't replicate this on 4.0.91. Can you confirm it still exists there?

If it does can you describe exact steps to replicate the issue?
