Validate of a Topology finishes quickly, and no topology errors are discovered where errors actually exist.
This can be due to issues such as:
- There is a feature in the Topology that contains a NULL subtype value. NULL subtypes are not supported by the Geodatabase.
- The data is in an ArcSDE Geodatabase, and one of the feature classes participating in the Topology is in load-only mode.
Both issues can be resolved by installing ArcGIS Desktop 8.3 Service Pack 3.
