Hi,

I am having some trouble with the OnUpdateRecord event for a TQuery on a RemoteDataModule.  The event gets fired but the first parameter (DataSet) doesn't seem to be populated.

so, the following fails,

void __fastcall TMDbRDM::OnUpdateRecord(TDataSet *DataSet,
      TUpdateKind UpdateKind, TUpdateAction &UpdateAction)
{

    TQuery *aQuery = dynamic_cast<TQuery*>(DataSet);
...
...

At this point, aQuery == NULL.

How can this be?  

TIA.

Andy
