[fdo-users] AutoCAD Map3D and Oracle FDO Issues

[Martin Morrison]

Mike,

My reference was to the question about triggers...not the type of geometry.

This issue requires a database-end workaround, which varies depending on 
DB software.

That said, who is at fault? Is it an issue with AutoCAD Map3D or FDO? If 
it is an AutoCAD issue, should FDO be responsible for inserting/updating 
the same geometry type as the feature source? Is AutoCAD intentionally 
mixing single and mixed geometries, and is this allowed among some or 
all providers? I never bothered submitting at ticket on this issue since 
I wasn't sure what exactly the issue was and who to blame.
