You need to set the mapper id field as editable.
Here is what I had to do to use a MappedStringIndex as a primary key
that I can set manually:
/* MAC address as primary key */
def primaryKeyField = mac
object mac extends MappedStringIndex(this, 17) with IndexedField
[String] {
override def dbDisplay_? = true
override lazy val defaultValue = randomString(maxLen)
/* allow user-defined primary key */
override def writePermission_? = true
override def dbAutogenerated_? = false
private var myDirty = false
override def dirty_? = myDirty
override def dirty_?(b : Boolean) = { myDirty = b; super.dirty_?(b) }
override def fieldCreatorString(dbType: DriverType, colName: String):
String = colName+" CHAR("+maxLen+") NOT NULL "
}
