[SNMP4J] SNMP table : row data get override by the recent rows

[Frank Fock]

Hi,

How is the variable "id" initialized in row
               MOTableRow<Variable> row = 
moFactory.createRow(new OID(new int[] { id }), initialValues);


I do not see that anywhere.

Please fix your code first, before asking again. Also a simpler
code example would be helpful, which conentrates on the SNMP4J-Agent
code and not your project stuff.

Best regards,
Frank
