Hi folks,
Hope this topic will be read.
I'm getting a similar problem but using newIstance instead of parse.
Here is my code:
<code>
SchemaTypeLoader stl = XmlBeans.typeLoaderUnion( new SchemaTypeLoader[]
{ x.y.MyPrefixEventNameDocument.type.getTypeSystem(),
XmlBeans.getContextTypeLoader()} ) ;
SchemaType st = stl.findDocumentType(new QName("","EventName","MyPrefix"));
//I don't use namespace
EventName evt = (MyPrefixEventNameDocument)stl.newInstance(st, null);
</code>
The problem is that I have another class a.b.AnotherPrefixEventNameDocument
(same root element in 2 XML buffers), so I'm getting this exception:
java.lang.ClassCastException: a.b.impl.AnotherPrefixEventNameDocumentImpl
Can you help please?? (I'd like to avoid using namespaces if possible :) )
