TFoam weight histogram

I have found the new module TFoam in ROOT 5.13 which works just fine for me. The only problem I have is that the name of the histogram for the weight in TFoam is fixed, and it gets re-crated if one is trying to use two substances of TFoam in one script, which causes inconvinience.

Does anyone know how to deal with this ?

Any suggestion will be greatly appriciated…

I fixed the problem in the CVS version.
As a workaround in your version, call
before the creation of the TFoam objects.
