> NullPointerException when using reference on XmlSchemaElement from imported

> Key: AXIS2-987
> URL: http://issues.apache.org/jira/browse/AXIS2-987
> Project: Apache Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: wsdl
> Reporter: Fabian Christ
> Attachments: sample-wsdl.zip, SchemaCompiler.patch.txt
>
>
> You have the following situation:
> A WSDL file uses X.xsd for types and X.xsd imports Y.xsd. Now an element of
> X.xsd references an element of the imported Y.xsd.
> At this point the SchemaCompiler crashes with a NullPointerException when
> trying to handle the referenced element.
> Exception in thread "main"
