[gnome-db] calendar doen't work when use GdaQuery

[paragasu <paragasu gmail com>]

i have postgresql table with one column of type date.

if i use GdaCommand for SELECT,  gnome_db_raw_form will display a very nice
calender dialog for the date entry.

but i use GdaQuery (which i have to), gnome_db_raw_form will disable
the calendar dialog.
only the inactive button beside the date entry displayed.

is there anything i can do to make the calendar dialog working again?
thank you.

p/s:i am using V3. not going to V4 yet.
