ERROR
Zooming out/in to a feature in a parcel fabric in ArcMap causes drawing errors. The value of the subtype code is NULL
Error Message
While zooming in\out of a selected parcel in a parcel fabric in ArcMap, the following error message is returned:
One or more layers failed to draw: The value of the subtype code is NULL.[(class name: <objectclass_name>, oid: <ObjectID>)]
Cause
The feature identified by the error message has a subtype value of null. Null subtype values are not supported in geodatabase feature classes involved in topologies or parcel fabrics. They are supported in feature classes which participate in a geometric network but cause an error in the Build Error table.
Solution or Workaround
If a subtype field is defined for a feature class, each feature in that feature class must have a valid subtype value. Features for which a valid subtype value does not exist cause drawing errors when the feature is selected.Instances may arise where features do not have a valid subtype value. A new subtype value can be added to act as a placeholder for the null field value. Depending on the subtype values already in place, the new subtype value could be 0, 1, 9999, etc. Creating the new subtype and assigning it all features with a Null subtype null allows the validate to proceed.
