[mapguide-users] Preview layer created from SQL Server data source

[_Jon_]

Hello,

I have created a SQL Server data source, defined a feature class, and copied
a bunch of polyline features into it.  When I preview the feature source in
Maestro, I can see my feature class listed with the attributes (and key)
that I defined.  If I click View Data from the feature source preview, I can
see all of the data associated with the features and if I click View
Feature, I can see those features graphically.  however, when I create a
layer from this feature source and define a basic style for the Line
features, the layer (or perhaps just the preview function) does not appear
to work properly.  If I try to preview the layer, I get the exception below. 
Needless to say, if i try to build a MapDefinition or ApplicationDefintion
using this layer, it also doesn't work.   Any idea what could be going wrong
or how to fix it?

Here is the exception:

System.Exception: The remote server returned an error: (559)
MgDbXmlException.: The custom error module does not recognize this error.
---> System.Net.WebException: The remote server returned an error: (559)
