[ROOT] Can't call TH3::Project3D()

Hi Rooters,

 I can't call TH3::Project3D() and ProjectionZ() methods. However some
others like TH3::FitSlices() work. What is the problem?

Example is in this macro:
{
 h3 = new TH3D("h3","h3 test",10,0.,1.,10,0.,1.,10,0.,1.);
 h3->FillRandom("pol1",1000);
 h3->Draw();  
// h3->ProjectionZ();   
// h3->Project3D("xy");
h3->Project3D("xy")->Draw();    
}

And here is the output

root [23] .x bug.C
Warning in <TH1::Build>: Replacing existing histogram: h3
Error: Can't call TH3D::Project3D() in current scope
