----------------------------------------
An additional item with this issue is that the changeType in the previous comment appears to work in that it does not report an error. Would have been nice to have an error indication that it did not actually work.

Here is the original email from the xml beans user list the prompted me to write this ticket:
Subject: RE: Problem Using changeType On execQuery Result

Hi James,
changeType only works successfully if AddressType is a document type. Currently, there is no way to type an XQuery result if the type of the element returned is not a document type. It's obviously a serious limitation and we're aware of it...you can open a bug in Jira for tracking purposes.

Subject: Problem Using changeType On execQuery Result
I am trying to read the result of an execQuery. My xml document (give at the end of this email) gives test data (namely what accounts are used for each test). I have written an xquery expression to figure out the account ids to use for each test.
Here is the code I am trying to get to work:
TestDataDocument testDataDocument = TestDataDocument.Factory.parse(new File("aws-test-data.xml"));
String queryExpression =
"declare namespace aws='http://test.aws.couball/data'; "+
"for $a in /aws:test-data/aws:tests/aws:test[@name='Test1']/aws:accountref/@name "+
"return /aws:test-data/aws:accounts/aws:account[@name=$a]";
XmlObject[] xmlObjects = (XmlObject[]) testDataDocument.execQuery(queryExpression);
log.debug("xmlObjects.length="+xmlObjects.length);
for (XmlObject xmlObject : xmlObjects) {
log.debug(xmlObject.getClass().getName());
AccountType account = (AccountType) xmlObject.changeType(AccountType.type);
log.debug(account.getClass().getName());
log.debug("account.getId()="+account.getId()+", account.getName()="+account.getName());
}
I believe that I am getting the right data selected in the xquery expression since I can use a cursor from each xmlObject and traverse to see all the nodes I expect. The problem is with utilizing changeType. The account object in my sample always returns null for getId() and getName(). AccountType is a generated xmlbeans object from my schema. Am I missing something here with .changeType? Or am I on the wrong track. Any advice would be appreciated.
Here is the log output I receive when running this snippet:
