[postgis-users] geom null

[ju]

Hi list,
i have imported a table in postgres with only data fields.
i add a geom field and i would like to digize object, for example with Qgis or GV sig.
my table record is visible in qgis or gv sig but impossible to digitize...
i think the trouble is not qgis or gvsig but a trouble of concept : is it possible to digitize a geom in postgis table if the record ( with geom null) allready exist ?

thanks for helping,
