In principle, you could test whether TArrayI is processed correctly, because our case is basically the same, with the difference that the array will not be recreated if the size is reduced. The behaviour in browsing is the same. > There are sometimes class constructions non trivial to support when > an abstract class is found during the split mode.

Well, abstract base classes are a nice instrument to define interfaces, but for classes forseen to be written into a tree in split mode, it might be easy enough to avoid them. So if itīs tricky to support these cases, a warning in the TTree documentation should do the job. Best regards, Volker -- Dr. Volker Hejny Tel: 02461/616853 ** Institut f.
