Exception when adding snmpGroup to Mib class

[christel.sohnemann____philips.com]

Hi everybody,
When adding a newly created snmpGroup object to a Mib object (as it is demonstrated in agent++ examples) I get an exception. (I cannot really locate the origin of the exception, as the code, where it is thrown is in MibContent object and this is 
encapsulated in a TS_SYNCHRONIZED macro so I cannot step into it).
My question is: what is the snmpGroup object used for? Is it always required? Do I really have to add a sysGroup object before to Mib object?
The online-docu is unfortunately not really helpful concering this topic...

Any help is really appreciated!
Thank you in advance,
Christel Sohnemann
