Hi,

XPAND does not find the root element definition.

SEVERE: Error in Component  of type org.eclipse.xpand2.Generator:

For easy reproduction I uploaded the project: http://drop.io/aeypm9d

Please show me what I cannot find myself.

hi the problem is that your xsd does not have any target namespace set

you can workaround this modifing your xmlreader like this

<component class="org.eclipse.xtend.typesystem.xsd.XMLReader">
		<modelSlot value="model" />
		<uri value="root.xml" />

		<option key="NAMESPACE_MAP">
		  <val class="org.eclipse.xtend.typesystem.xsd.lib.MapBean">
		    <mapping to=""
		             from="http://www.example.org/test" />
		  </val>
		</option>

		<metaModel id="mm" class="org.eclipse.xtend.typesystem.xsd.XSDMetaModel">
		    <schemaFile value="root.xsd" />
		</metaModel>
	</component>

Hi Christian,

Thank you for the answer. But this time I am not sure that it is right.

First, I am quite sure that it worked before with other XSDs without target namespace.

Second, I tried it as shown below, and the error message is still the same.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3.org/2001/XMLSchema" >
  <xs:element name="Entity">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="xs:Name"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="Name">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:string">
          <xs:attribute type="xs:string" name="Type" use="optional"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
  <xs:element name="root">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="xs:Entity" maxOccurs="unbounded" minOccurs="0"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

And I adapted the DEFAULT_NAMESPACE option, and tried without it.

The original project is still on drop.io, if you want to check it.

hi,

the target namespace is obvious wrong but you should still be able to change it with NAMESPACE_MAP

Hi,

I found the problem. Actually I don't need a target namespace. There was just the obsolete line about the namespace in the xml instance.
