Problem with FF4 and Intraweb

SysRq

I have the following code: (aMasterDataSet is a TDataSet descendant)

    FfrxDBDataset := TfrxUserDataset.Create(self);
    
    FfrxDBDataset.UserName := aMasterDataSet.ObjectClass.ClassName;
    FfrxDBDataset.OnCheckEOF := CheckEOF;
    FfrxDBDataset.OnFirst := frxDatasetFirst;
    FfrxDBDataset.OnNext  := frxDBDatasetNext;
    FfrxDBDataset.OnGetValue := FindValue;

    FReport.EngineOptions.SilentMode := true;
    FReport.EngineOptions.EnableThreadSafe := true;
    FReport.EngineOptions.DestroyForms := false;
    FReport.EngineOptions.UseFileCache:= false;
    FReport.EngineOptions.UseGlobalDataSetList := false;
    FReport.DataSets.Clear;
    FReport.EnabledDataSets.Clear;
    FReport.DataSets.Add(FfrxDBDataset);
    FReport.EngineOptions.ReportThread := self;
    FReport.ShowProgress := false;
    FReport.EnabledDataSets.Add(FfrxDBDataset);

When I comment the line

FReport.EngineOptions.UseGlobalDataSetList := false;

my report is working (the OnFirst / OnCheckEOF /.. are triggered). When UseGlobalDataSetlist is disabled (as is described in the help section) the OnFirst /.. are not triggered anymore.

Any idea for a workaround?

Nobody?
