Linking LazReport to a DataSet in RunTime

Hi!. I'm triyng to link a DS Dataset to a tfrDBDataset object to make
a report with lazreport. In design time it's very easy but, when I try
it in runtime with these sentences:

  DSInforme:=tFRDBDataSet.Create(Self);
  DSInforme.DataSet:=DS;
  Informe:=tFRReport.Create(Self);
  Informe.Dataset:=DSInforme;
  Informe.LoadFromFile('InformeReuniones.lrf');
  Informe.DesignReport;

 The report designer doesn't find any dataset (menu
Tools->Tools->Insert DB fields), so I can't add any fields to the
report. I'm sure the DS component contains data because I've linket it
to a DBGrid to.

So. What am I doing wrong?  :?:

I copied & pasted your lines of code in my sample project and here it
works fine.

What Lazarus revision?, what type of dataset?. Even better, Please
create a bug report and attach a sample project so I can try to
reproduce the problem.
