I got a problems after saving into TTree in the split mode the objects
containig ULong_t members.
After quite a while I investigate that the problem is caused by that
members and finally I found in the doc to TBranch.html that this type is
not supported by the TBranch.
I wondering if it's possible to generate the warnings in the case of
users attempt to use the unsupported types in the tree?
It could save a lot of time for somebody.
Best regards
Valeri
