[ROOT] type conversion problem (?)

Hi,

I've probleme  with the TTree::GetEntries() method.
In the following code, _entries_ is set to nan.

	TFile *f;
	TTree *tree,*tree2;

	double entries;


	f= new TFile("path to file");
	tree2=(TTree*)f->Get(hname);
	tree=(TTree*)tree2->Clone();
	delete tree2;
	f->Close();
  
            entries=tree->GetEntries();
	cout << entries << endl;

Does anyone have an idea ? Could it be a compilator problem ?
