How to set errors in TH2F histogram?

ROOT

Hi All,
I have a simple question, how one can set error bars in TH2F histogram?
When I try
TH2F *test=new TH2F(“test”,"",10,0,10,10,0,10);
test->Fill(2,2);
test->Fill(4,3);
test->SetBinError(2,2,1);
test->Draw();

I see no errors on the plot, when I use TH1F it works, but why it doens’t work with TH2F?
Thanks
Pavel

Instead of
test->Draw();
do
test->Draw(“e”);

Dear Rene,
I tried “e” option too, but it doesn’t help, I’m using Version 4.04/02f

Drawing of errors for TH2s was only implemented in version 5.
Move to version 5.11/06
