XMLBeans 2.0 - Problem with derived/extended schema elements

Question

Hi,
I have a schema which takes a list of "Record" types. Each 'Record' is complex type of SenderDetails, Recipientdetails, shipdate, description and Ref elements. The main.xsd is as follows:
<xs:element name="records">
<xs:complexType>
<xs:sequence>
<xs:element name="record" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="SenderDetail" type="cmn:AddressType" />
<xs:element name="Shipdate" type="xs:string"/>
<xs:element name="RecipientDetail" type="cmn:AddressType" />
<xs:element name="Description" type="xs:string"/>
<xs:element name="Ref" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>     
Now, the SenderDetail and the RecipientDetail may be of type 'Employee' or 'Department'. Employee and Department are both derived from 'AddressType' as shown.
<xs:complexType name="Department">
<xs:complexContent>
<xs:extension base="cmn:AddressType">
<xs:sequence>
<xs:element name="Name" type="xs:string" />
<xs:element name="keyvalues" type="cmn:Valuelist"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:complexType name="Employee">
<xs:complexContent>
<xs:extension base="cmn:AddressType">
<xs:sequence>
<xs:element name="Name" type="xs:string" />
<xs:element name="Title" type="xs:string" />
<xs:element name="Empid" type="xs:string"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
After mapping the schema to java objects, here I am using the following code to check whether the 'SenderDetail' in the incoming xml is of type 'Employee' or 'Department'.
'records[]' is the array of records already extracted from incoming xml.
Here the output of "System.out.println( records.getSenderDetail() ); "
Output:
<xml-fragment xsi:type="o:Employee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="SomeX/Records"
xmlns:o="SomeX/Stakeholder"
xmlns:c="SomeX/CommonTypes">
<c:street1>456 Oak Lane</c:street1>
<c:street2>Second floor bld I</c:street2>
<c:city>xxx</c:city>
<c:state>xxx</c:state>
<c:country>US</c:country>
<c:zipcode>xxx</c:zipcode>
<c:phone>xxx</c:phone>
<c:comail>xxx</c:comail>
<o:Name>xxx</o:Name>
<o:Title>xxx</o:Title>
<o:Empid>xxx</o:Empid>
</xml-fragment>
Now I am expecting the output of the following code
AddressType p = records[i].getSenderDetail();
if (p instanceof Employee){
System.out.println("Sender is of type Employee");
}else if (p instanceof AddressType){
System.out.println("Sender is of type AddressType");
to be "Sender is of type Employee"
But I am getting "Sender is of type AddressType"
records[i].getSenderDetail().schemaType() on this record is giving me the base schema type "AddressType"
How can I get the derived schema type ? How can i know whether this is a Employee/Department type?
Thank You.

If your query1 is something like
SELECT ...
d.deptno,
FROM
...dept d
WHERE ...
and you want to do query2
SELECT ...
FROM ...
for all departments but then split the output on display by department.
I'd go with the suggestion from the other poster above:
Do your query1 as
SELECT ...Query1Fields,
Query2Fields
FROM Query1Tables, (put query2 here) q2
where q2.deptno = dept.deptno -- or whatever the conditions are
Or use
WITH q2 AS (put query2 here)
SELECT ...Query1Fields,
Query2Fields
FROM Query1Tables, q2
where q2.deptno = dept.deptno -- or whatever the conditions are
That second format should ensure that query2 is done as one whole unit.
Then in the data model drag and drop the query2fields outside the query1 group to form a new group below it. Then in the layout you have a repeating group based on the query1 group and within it a repeating group based on the new "query2" group.
