forms - symfony2 validation of child entity prevents editing of parent entity -

i have run problem couple of entities thought try , hang of goes on, , turn best source here (will add bounty question eligible).

my user part of user group. have validator usergroup entity make sure no 2 usergroups have same name.

the problem when go editing user, , try select usergroup user, symfony2 behaving if trying create usergroup same name, when in reality doing trying select usergroup user.

a user entity

your nameexistsvalidator this:

• fail if find any user-group name i'm checking.

but think want this:

• fail if find another user-group name i'm checking.

in other words: validator needs complete usergroup entity (or @ least id , name) check user-group same name different id.

symfony 2 has uniqueentity validator, why don't use it?

using annotations this:

/**  * @orm\entity  * @assertuniqueentity(fields={"name"}, message="this name exists")  */ class usergroup {
