[fdo-internals] IInsert.BatchParameterValues problems

[Greg Boone]

So you have managed code available that illustrates?

Hi Orest,

If I understood well - in case provider does support parameters, managed
IInsert will get instantied with BatchParameterValues propery containing
empty BatchParameterValuesCollection collection. Otherwise - the property is
Nothing (Null)... Something's strange here, the collection should exist in
first place neverthless of provider's capabilities (it should throw an error
afterwards, on IInsert.Execute).

Is this an error in managed wrapper or a feature? :-)

Regards,
Maksim Sestic
