Renaming fields with FieldDefinitionName does not work

If the generated field name in Litium does not contain the value set by FieldDefinitionName setting in inRiver check the following.
1. Is connector restarted?
2. Are there any other fields with the same name or renamed to this? Perhaps the field attributes are contradictory.
3. Is the FieldDefinitionName attribute name is correct? check for spellings and remove any spaces at the end.
