0646a0e8 18Revision 1.7 2001/02/13 16:53:35 nilsen
19Fixed a but when trying to use GEANT4. Needed to replace
20if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
21because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
22did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
23to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
24in the same way as in AliITSv5.cxx.
