FeatureClassDefinition.GetAreaField and GetLengthField does not use qualified name - bug?

[MadsHoumann]

On a featureclass with a join, calling FeatureClassDefinition.GetAreaField and GetLengthField does not return the qualified name (including table prefix). 

But GetObjectIDField and GetShapeField both do.

Is this a bug?

Or is there are workaround? A reliable way to get relevant qualifier?

The area and length fields are not real fields, they are synthesized fields. You shouldn't need to fully qualify them.

OK. Thanks. I'll see if I can make that work.
