problem with get_next when ipAddress as table index

Hi all

 

I have a table with 4 indices, 3 of them are of type ipAddress (see MIB
below).

Using mib2c with "mib2c.raw-table.conf" configuration file I got a c
file with function
"nsCommonConfigDataForwardRoutesTable_get_next_entry".

On the "get-next" function 

* I receive the indices

* get the information from server

* updated the table's row

*updated the indices (idx->val.integer) with new value (next)

But the next time the function is approached (on "walk") - it does not
"remember" the indices of type ipAddress, but it does remember the int
index. 

"idx->val.integer" is zero for the first 3 indices (of type ipAddress)

AM I DOING SOMETHING WRONG?

I also copied the function below.
