[SNMP4J] MOTable

[Frank Fock]

Are you sure that you are implementing your own
MOTableModel? It seems to me (because you are
registering real rows) that you are using the
DefaultMOMutableTableModel.

I meant to implement a class that only creates
TableRow instances when required (thus on-the-fly).

Best regards,
Frank
