Do not imply that user actively selected object policy
Policies can be defined by forms which may hide the Edit/View Policy fields.
Thus the current error message "You can not select this edit policy" is misleading as the user may not have been able to actively select a policy.
Overwrite the message by a more correct one (which is likely still confusing but hard to make it more specific as this message is shown in many places).
