I'm doing exactly the same and it should work. Here are my pseudo code to
accomplish that:

with IB_query1 do begin
RefreshOnParamChange:=True;
Search;
... // user hits preview
IB_Connection.BeginBusy(true);
Open;
sl:= TStringList.Create;
WriteSearch(sl);
... // retrieve user's filter conditions
IB_DataSource1.DisableInterface; // to keep working master/child
relations
frReport1.ShowReport; // call report in FastReport
IB_DataSource1.EnableInterface;
Search;
IB_Connection.EndBusy;
end;

If you are doubting that dataset is updated add a visual control (TIB_Grid)
to your form temporally and check it before calling report preparation.

Subject: [IBO] Passing parameters before posting a search
