Hello,

I have a collection property called "Rights" (ISet) with a "User" root object User. Im looking desesperately for a way to get an additionnal field
that would count the number of elements in my "Rights" Collection. I'd want also to have the User object as the returned parameter :

The following query don't seem to work, nhibernate claims for a more detailed description of User object.



gives the following exception :

System.ArgumentException: Item has already been added. Key in dictionary: 'usr' Key being added: 'usr'

Any idea ?

thanx in advance.

Sam

Re,
my problem is related to this JIRA item : http://jira.nhibernate.org/browse/NH-528

I have voted. Is there any plan to correct this bug ?

There are other things that have higher priority right now. You can work around the bug by specifying all properties of your User object, i.e. 'group by usr.Property, usr.AnotherProperty, ...'.

I have more that 40 fields, gloups
Anyway...
