[mapguide-users] "Failed to read schema..." error with GDAL

[Hardt]

Hi,

I created a raster datasource with GDAL.

When I create a layer using this datasource, after I selected the Feature
Resource, I get an error message saying 

"Failed read schema from data source.
The operation gave the error message: Value cannot be null.
Parameter name: input"

http://n2.nabble.com/file/n4164488/Capture.png 

After that, I can select a schema (always default:default), and in the
Raster field, sometimes I get "image", sometimes I get "raster" (it seems to
depend on which editor I used when I created the datasource)

I found no error in MG logs, and the DescribeSchema tool gives me this:


<?xml version="1.0" encoding="UTF-8" ?> 
- <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"

  </xs:key>

  </xs:simpleType>
  </xs:element>
  <xs:element name="Raster" type="fdo:RasterPropertyType"
fdo:defaultImageXSize="1024" fdo:defaultImageYSize="1024" /> 
  </xs:sequence>
  </xs:extension>
  </xs:complexContent>
  </xs:complexType>
  </xs:schema>


I can use the layer in a map, but as I explained in another thread today,
there are other problems with coordinate systems etc...

What means the "schema" error, and how can I fix it?

Thanks,

Hardt
