null values in GML

[Bart van den Eijnden (OSGIS)]

Hi list,

I have a strange phenomenon.

A shape attribute table has some null values in it (column type Real), for
instance:

OGRFeature(nap_speciaal):856
  pnt_pntid (String) = 000A2510
  ..
  hgt_hgtwd (Real) = (null)
  ..
  POINT (122880 487860)

Using Mapserver WFS I get the following GML output:

        <ms:pnt_pntid>000A2510</ms:pnt_pntid>
        ..
        <ms:hgt_hgtwd>************************</ms:hgt_hgtwd>
        ..

Does anybody have an idea what is causing the sequence of asterisks?

Best regards,
Bart
