libgdamm select returns only NULL values

["Alex Biddle" <heuristic gmail com>]

Hi,

I want to use libgdamm as part of a Gtkmm application, but can't get
some tests to work.

I've created an SQLite database, and can connect to it fine. However
when I issue my SELECT query, and use the resulting model to display
the resultset via std::cout, it only returns NULL.

Output [annotations]:
NULL [from value.to_string()]

id   | numbers [from model->dump_as_string()]
-----+--------
NULL | NULL
NULL | NULL
NULL | NULL
NULL | NULL

Apologies if this isn't the correct place to ask.

Regards,
Alex Biddle.
