Error message

Yamby

I've just downloaded the version 3.04.

I've the following error message when I print a report I've created with a previous version :
"Cannot use the same dataset for Report.DataSet and Page.DataSet"

I don't understand this message :
- It worked well with the v3.03
- I see the property DataSet of a page...but not the Report's one...

Any idea?

Do not set the TfrxReport.DataSet to the same dataset as Page.DataSet or Band.DataSet.

Yamby

In my case, the TfrxReport.DataSet and the Page.DataSet are set to NULL
Only the Band.DataSet is defined...

This may be due to a bug in the FR3.04. Change the frxClass.pas:

function frxFindDataSet(DataSet: TfrxDataSet; const Name: String;
  Owner: TComponent): TfrxDataSet;
var
  i: Integer;
  ds: TfrxDataSet;
begin
  Result := DataSet;
  if Name = '' then
  begin
    Result := nil;
    Exit;
  end;
  if Owner = nil then Exit;
  for i := 0 to DatasetList.Count - 1 do
  begin
    ds := DatasetList[i];
    if AnsiCompareText(ds.UserName, Name) = 0 then
      if not ((Owner is TfrxReport) and (ds.Owner is TfrxReport) and
        (ds.Owner <> Owner)) then
      begin
        Result := DatasetList[i];
        break;
      end;
  end;
end;
