If the selection set supplied to the Validate Features function contains a feature with a Null subtype value, Validate Features will return a false positive indicating that all features are valid, even if invalid features are present.
If the features participate in a Geometric Network and Connectivity rules are being validated, Validate Features will return a false positive if any connected features have Null subtypes.
The following types of validation rules are affected:
- attribute rules
- network connectivity rules
- relationship rules
The selection set contains a feature with a Null subtype value. If the features are in a Geometric Network, the connected features with Null subtype values cause Validate Features to return a false positive.
