OK - so you are using the 'table_data_set' helper.
That's useful information.
This particular helper is designed for holding the data for the table within
the agent itself. So the agent knows what rows exist in the table,
and can provide the relevant values itself. Your handler is optional,
and will only be called once the helper has finished processing the request.
So this helper relies on you populating the table with initial contents.
See 'examples/data_set.c' and 'testhandler.c' (both in agent/mibgroup)
for examples.
>From the code you've provided, you don't seem to be populating the table
with anything. So when the agent received a request for this (empty) table,
it returns the information that it has (i.e. nothing).
So no - your handler will never be called.
You need to populate the table (or use a different framework)
