Dear Developers,

I believe I've found a bug in TNtuple.Fill() (and presumably in TTree as 
well) when only one branch is defined, to whit

1) the normal behaviour say for two branches works fine
	TNtuple *toto=new TNtuple("toto","toto","wah1:wah2");
	toto->Fill(20.0,25.0);

2) for a single branch
	TNtuple *toto=new TNtuple("toto","toto","wah1");
	toto->Fill(20.0)
causes an error.

While I'm at it what is the best way to store simple float arrays in ROOT 
files ? Since TArray does not derive from TObject I'm forced to use one 
branch ntuples.

Kind regards

Malcolm
