Re: [Brahms-dev-l] root issue

   Hi,

   On the same subject with new root... Remember the old inoffensive 
warnings (well, Christian thinks them not so inoffensive...)

Warning in
<TClass::TClass>: no dictionary for class BdstRun is available
<TClass::TClass>: no dictionary for class BdstGlobal is available
<TClass::TClass>: no dictionary for class BdstMrsTrack is available
<TClass::TClass>: no dictionary for class BdstTrack is available
<TClass::TClass>: no dictionary for class BdstMagnet is available
<TClass::TClass>: no dictionary for class BdstTof is available

   Branches from trees giving these warnings gave me 0, but at the 
same time, other branches were fully readable... So, I had to load 
the libDstData.so, and everything was working. The same for other 
trees, not only dst.

Kind regards,
Catalin.
