The map.extents property doesn't work fine if there are more than one geometry field into a single table

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Create a table with 2 geometry fields. Fill only the second field with a 
geometry, leave the first 
field null (in order as they are created in the table)

2. SqlServerFeatureSource SqlSpatial = new 
SqlServerFeatureSource(.CG_ConnString,"Table");
   Layer l = new Layer();
   SqlSpatial.ForcedGeometryColumn = "SecondField";
   l.Data = SqlSpatial;
   m.Width = CG_PictureBoxGIS.Width;
   m.Height = CG_PictureBoxGIS.Height;
   m.Extents = SqlSpatial.Extents;

3. this will cause an error because it search the extension in the first 
Geometry field instead of the 
SecondField

If I invert the geometry fileds (the first filled with a geometry, and the 
second left to null) it works 
fine

What version of the product are you using? On what operating system?
