getting error when selecting a legacy Oracle table with composite key in the domain

[JWTeunisse]

Getting strange error in the select statement when connecting to a legacy Oracle table with a composite key. Hybernate tries to select a column users_id while the column name is user_id.
Here's the domain class UserGroup followed by the error message.

package cvh_beheer

class UserGroup implements Serializable {
// String id
String userid_type
String userid
String grouping_type
String groupid
Date valid_from
Date valid_until
String toString() { return userid+': '+groupid}

static constraints = {
}
// mapping naar schema coadmin en tabel USER_TO_GROUP
static mapping = {
table 'COADMIN.USER_TO_GROUP'
version false
id column:'USERID_TYPE'
id column:'USER_ID'
id column:'GROUPING_TYPE'
id column:'GROUP_ID'
id composite:['userid_type', 'userid', 'grouping_type', 'groupid'], generator:'assigned'
sort id: "asc"
columns {
userid_type column: 'USER_ID_TYPE'
userid column: 'USER_ID'
grouping_type column: 'GROUPING_TYPE'
groupid column: 'GROUP_ID'
valid_from column: 'VALID_FROM', type: 'date'
valid_until column: 'VALID_UNTIL', type: 'date'
}
}

static belongsTo= [users:Users]

/* JWT uitgezet
def beforeInsert = {
laatste_update_datum = new Date()
creation_datum = newDate()
}
def beforeUpdate = {
laatste_update_datum = new Date()
}
*/
}

Error message:
Error 500: Executing action

  Any help or suggestions to solve this or is it an Grails error?

This looks like you created the UserGroup domain model more like a database table than an object, not positive without seeing the Users domain model, but that
might be what is going wrong. for example the beginning of the UserGroup domain object should look more like this:

class UserGroup implements Serializable {
// String id
String userid_type
Users user
String grouping_type
Group group
Date valid_from
Date valid_until
String toString() { return userid+': '+groupid}


where the only changes I made reflect id's from other tables/domain objects.
Hopefully this helps if you haven't already solved the issue.
