[AGENT++] AGENT++ How to use Octet string as index in dynamic table?

[Alexander G. Nilov]

Hi All!
--
I need to use octet string as index in dynamic table,
I tryed

const index_info indServiceTable[1] =
  {
      { sNMP_SYNTAX_OCTETS, FALSE, 0, 255 }
  };

first column is octet string,
add_col(new MibLeaf("1", READONLY, new OctetStr("")));

then I created and filled a row:
row = add_row(*C_Style_Str*);
row->get_nth(0)->replace_value(new OctetStr(*C_Style_Str*));

but in agent`s response is integer (1) in oid in that branch (..1.x 
...), there are no index string

... .1.1   octet string
... .1.2    integer
... .1.3    ...
... .1.4     somthing else

...

Whats wrong?
Can you post an example - creation of such table?
