Hi Hardt, In the "About..." menu, can you select the "view last exception", and send the message to this list?

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"; targetNamespace="http://fdo.osgeo.org/schemas/feature/default"; xmlns:fdo="http://fdo.osgeo.org/schemas"; xmlns:gml="http://www.opengis.net/gml"; xmlns:default="http://fdo.osgeo.org/schemas/feature/default"; elementFormDefault="qualified" attributeFormDefault="unqualified"> -<xs:element name="default" type="default:defaultType" abstract="false" substitutionGroup="gml:_Feature"> -<xs:key name="defaultKey"> <xs:selector xpath=".//default" /> <xs:field xpath="FeatId" /> </xs:key> </xs:element> -<xs:complexType name="defaultType" abstract="false"> -<xs:complexContent> -<xs:extension base="fdo:ClassType"> -<xs:sequence> -<xs:element name="FeatId"> -<xs:simpleType> -<xs:restriction base="xs:string"> <xs:maxLength value="256" /> </xs:restriction> </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
