Einav, is this something that should be fixed? As far as I know, all frontend validation nowadays only checks that the input is technically valid, not if names are already taken.

indeed - client validations are currently not checking name uniqueness - we are relying solely on server validation to do that.

the problem described in this bug is not that there is no client validation; the problem is that the server validation (namely, CanDoAction) results are not propagated properly to the UI (namely, no dialog with the CanDoAction details pops up, as should happen with any CanDoAction failure).

we had a bug that prevented any CanDoAction dialog from appearing after engine restart [http://gerrit.ovirt.org/#/c/18729/, Bug 968362], but it has been fix.
[the fix was merged (Sep 4) after this bug has been reported (Jul 24)].

@Mike - can you please test to see if the problem is still reproducible on latest master? If so, it means that the problem is not related to Bug 968362 and further investigation is required in order to find out why the CanDoAction failure dialog is not popping up as it should.

Thanks.

Yes, upon more careful reading I see you are perfectly correct. I checked, and while there's an error popping up now, it does pop up only after the dialog closes, so that should still be fixed.
