[Rivet] Problema usign Hist2D

[João Barata]

Hi,

I was trying to make a 2DHisto and I use a "standard" declaration to do
this:

in function init:
_h_PT_Zparton = bookHisto2D("PTparto_vs_PTZ",500,0,500,500,0,500,"Corr PT Z
e PT inicial","Parton","Z","");

in analyze:
_h_PT_Zparton->fill(inpt,zmom.pT()/GeV,weight);

and I declare it as  private member: Histo2DPtr _h_PT_Zparton;

Everything goes fine until I do rivet-mkhtml and I always get this error

which only occurs for the 2D histo.

Am I doing something wrong with rivet?

Many thanks,
