[mapguide-users] MgInsertFeatures clears the feature source

[mika at digikartta.net]

 Hi,
 I don't understand the function of the MgInsertFeatures method.
 I have SDF feature source in MG2011. If I do 
 MgFeatureService.UpdateFeatures with the MgInsertFeatures command, all 
 the previous data is gone. So doing for example five inserts, with one 
 insert command each, results one row (the last).
 Should there be some autogenerated id-column in the schema in order to 
 insert command function properly or what am I doing wrong?

 cheers,
