Import tool: Nodes not being saved in DocumentParser

In the DocumentParser (sub)nodes are not being saved. The reason is the following codepath:

else {
DocumentParser parser = new DocumentParser();
ImportableBean nestedBean = null;
PropertyUtils.setSimpleProperty(contextBean, field.getName(), nestedBean);
ParserContext nestedContext = new DocumentParserContext(context.getDocument(), context.getConfig());
nestedContext.setContextXml(nodeList.item(0));
nestedBean = parser.parse(repositoryDocument, subNodeClass, null, nestedContext);
}
