[SNMP4J] Unable to add rows with Rowstatus and TableUtils?

[johan.rask at jayway.se]

I found the error myself after looking at Snmp4jHeartbeatMib.
I was missing a RowFactory so adding on did the trick.

model.setRowFactory(new DefaultMOMutableRow2PCFactory());

Should there not be a default one, or is this not possible?
