Second item in collection won't get deserialized

[frankhommers]

I have put the example code and used XSD's in this zip file:

Example.zip

XmlSchemaClassGeneratorExample.csproj is the generator for the code. XmlSchemaClassGeneratorUseGenerated.csproj is the project which uses the generated code.

In project XmlSchemaClassGeneratorUseGenerated.csproj I deserialize:

But the second fes:PropertyIsLike (%ISLE) isn't deserialized into the object. Setting the GenerateComplexTypesForCollections to false also results in uncompilable code.

Is it a setting or a bug?

[mganss]

The latest version sort of fixes this. You'll probably have to set GenerateInterfaces to false, too. By sort of I mean there are scenarios where it doesn't work but it seems to work with this schema.

[frankhommers]

This works. But I am now using a NamespaceProvider. And that seems to exclude the Intersects XmlNode. I will try to isolate the issue.

[frankhommers]

I can't isolate that issue yet. But I have found another one.

Can you explain why:

        [System.Xml.Serialization.XmlElementAttribute("And", Type=typeof(BinaryLogicOpType), Namespace="http://www.opengis.net/fes/2.0")]
        [System.Xml.Serialization.XmlElementAttribute("Or", Type=typeof(Or), Namespace="http://www.opengis.net/fes/2.0")]

The Or gets the name Or. But And gets BinaryLogicOpType, which seems faulty.

Or should I open a new issue for that?

[mganss]

Both Or and And are (possible) root elements. There can be only one XmlRootAttribute on a class. That's why the Or class is an empty class that derives from BinaryLogicOpType.

[frankhommers]

Wouldn't it be possible to choose And as a name for And. What would be best in this case is:

BinaryLogicOpType would become an abstract class.

And and Or would both derive from that.

There are more similar example of this happening on other classes... I can point them out if you like, hopefully this can be improved...

[mganss]

I made And and Or both get their individual classes which derive from BinaryLogicOpType. Couldn't make it abstract because there may also be non-root elements which don't get individual classes that reference the base class.

Now your example works nicely AFAICT.

I'll report back soon. I guess in a week or two.
