When you say it could be an issue with your spatial reference or geometry storage type what do you mean?
Do you mean that a certain storage type is not supported? or are you talking about some kind of corruption issue with the storage .
I am having the exact same problem where I am using data from enterprise geodatabase (Oracle) and insight does not pick up the shape field .
The Storage type on the feature class i am trying to use with Insight is as shown ESRI LOB Spatial type. Any suggestion
or help is appreciated.
