Hi all, I´m currently using version 3.01 and observed the following behaviour when upgrading from previous versions. I store a class A in a tree, which contains a TClonesArray of class B. Two member variables of class B are of type TLorentzVector. The branch has been set using tree->Branch("name","A",&pA). When reading data written with this code, the 3-vector component of TLorentzVector is always zero. Setting the split level explicitly to 1, the data are valid again. Is this a wanted "feature"?
