When I trying to obtaing a "set" from a persistent class a get that error.

that is the arquitecture. It's a mnay to many relationship

Users >-----< UserGroups

in the User.java class have this

private set userGroups;

/**
* @hibernate.set
* role = "userGroups"
* lazy = "true"
* table = "user_group_details"
* @hibernate.collection-key
* column = "USR_ID"
* @hibernate.collection-many-to-many
* class="com.miradores.vmon.data.UserGroup"
* column = "USG_ID"
**/
public Set getUserGroups() {
return userGroups;
}

/**
* Standard setter
**/
public void setUserGroups (Set invar) {
this.userGroups = invar;
}


and this is the code for getting the set of usergroups

// Getting the User (it's ok beacuse when I print user properties they are OK)
User u = UserFactory.findByPrimaryKey( sess, usrId );

then when I try to use the u.getUserGroups();
the error ocurr

Don't know about your pb but you seems to map for hibernate 1.x (set role is replaced by set name). There are some threads about that on the forum.

Show us your mapping

The mapping is for version 2.0

It's generated with the middlegen plugin.
