Error in <TExMap::Add>: key 2 is not unique

Hello rooters!

Does anybody know this problem (i think is a problem). I have a class, child of a TObject, which has own Streamer. In this streamer i stream two members - classes, also children of TObject. These two members are pointers of type ClassA but actually they are any of classes ClassB or ClassC, that are children of ClassA, i use this procedure to stream:

R__b.WriteClass(classA1->Class());
R__b.WriteObjectAny(classA1,classA1->Class());
R__b.WriteClass(classA2->Class());
R__b.WriteObjectAny(classA2,classA2->Class());

and

TClass* cl=R__b.ReadClass();
classA1=(classA1*)R__b.ReadObjectAny(cl);
//delete cl;

TClass* cl2=R__b.ReadClass();
classA2=(classA2*)R__b.ReadObjectAny(cl2);
//delete cl2;

this reading gives the error:
Error in <TExMap::Add>: key 2 is not unique

that really confuse me. i cant afford any memory leak. so i am wondering why cant i delete classes cl and cl2. Also, it there any other posibility to stream classes classB and classC, which addresses are stored in classA1 and classA2.

thanks,
