Would it make more sense for the user (in terms of UX) to have a validation in the form instead of "not doing the requested changes" being his back?

I mean, you edit the name, put one of its alias, the form is red with proper error like "Cannot rename to an alias".

IMO disallowing bad behavior with explanation is better UX (educating user).

[Megafredo]

Yes indeed, having a visual way to communicate why adding the alias does not work can be a good approach (in terms of UX).

[SouadHadjiat]

I suggest we display an error message here to notify the user that the alias can't be named the same as the entity name.

Considering we leave the UX improvements for later, it looks ok to me !

Just thinking with Souad about a little missing piece at creation.
Alias should also be purged of the name when creating the entity.
Dont hesitate to join me to have more information @Megafredo
