DBImporter reads NULL-Integer as 0
Case:
- Import cases with DBImporter from PostGreSQL-DB
- Modell has an attribute A = Integer from 0 - 5
- Database record for A is NULL
- Expected: Attribute A in loaded case is unknown. Result: Attribute A in loaded case is 0.
Comments: If you change the range of attribute A in the modell to 1-5, you will get unknown. So the 0 in the attribute-range is the problem.
