Hi,
This might have been fixed in the newest version Maestro.
It was a problem with correctly parsing the schema xml.

Hi Kenneth,
I recreated the datasource and the layer, to be sure to have an error
message before doing what you said.
The error message popped out as always, but the "View last exception" option
says there is no exception to view.

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";

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
