This approach will be very inefficient for anything but data sets
where there is little likelihood of name collisions -- you have to
do an additional fetch for every collision. It's not clear what
your goal is here. If you're simply wanting to set temporary
distinct names (like window titles) for small numbers of objects,
this would probably be OK. If these will be permanent values for
an ever-increasing number of objects, then you'll need a different
approach...

What kind of approach you think ?
I have the same goal i want make unique a propertie but i don't find
solution for this.
I have think to perform this verification in the add methods of the
coressponding controller but i'm not sure it a good solution. Do you
think its good or not ? and what it is the best solution ?
