Xmlbeans and substitution groups

Question

I am working with the new GoogleEarth .xsd files and I have compiled them using xmlbeans. There are a number of elements that make use of substitutiongroups. for example:
<element name="Placemark" type="kml:PlacemarkType"
    substitutionGroup="kml:AbstractFeatureGroup"/>
  <complexType name="PlacemarkType" final="#all">
    <complexContent>
      <extension base="kml:AbstractFeatureType">
        <sequence>
          <element ref="kml:AbstractGeometryGroup" minOccurs="0"/>
        </sequence>
      </extension>
    </complexContent>
  </complexType>how do I "replace" the substitution group with the actual element so that instead of:
<AbstractGeometryGroup>
          <Point>
            <extrude>true</extrude>
            <altitudeModeGroup>
              <altitudeMode>relativeToGround</altitudeMode>
            </altitudeModeGroup>
            <coordinates>32.18582907768492, -107.85250271267361, 50</coordinates>
          </Point>
        </AbstractGeometryGroup>I would get just           <Point>
            <extrude>true</extrude>
            <altitudeModeGroup>
              <altitudeMode>relativeToGround</altitudeMode>
            </altitudeModeGroup>
            <coordinates>32.18582907768492, -107.85250271267361, 50</coordinates>
          </Point>I have tried casting, the substitute method, and the replace method to no avail. I think casting is the right way to go, but I throw a class cast exception when I try to cast. Here is my code
PointType point = (PointType)placemark.addNewAbstractGeometryGroup();
     AltitudeModeDocument altModeDoc = AltitudeModeDocument.Factory.newInstance();
     AltitudeModeEnumType.Enum altModeEnum = AltitudeModeEnumType.Enum.forString("relativeToGround");
     altModeDoc.setAltitudeMode(altModeEnum);
     point.setAltitudeModeGroup(altModeDoc);
     point.setExtrude(true);
     Vector<String> coordinates = new Vector<String>(3);
     coordinates.add("32.18582907768492,");
     coordinates.add("-107.85250271267361,");
     coordinates.add("50");
     point.setCoordinates(coordinates);With the cast exception thrown on the first line. Which I would understand, but I can call
placemark.setNewAbstractGeometryGroup(), which takes a AbstractGeometryType as an argument and will accept a PointType as an argument which I assume means PointType isa AbstractGeometryType. Is the issue that that I am casting the wrong direction? Any help is greatly appreciated. I would much prefer to build the xml messages using the beans rather then hacking together a StringBuffer.

Hi Pon -
Do you mean groups of users or group of pages?
If you mean groups of users, you can create your sub-groups as a regular groups, and then when assigning users to your Main Finance group ... add the 2 groups which are your subGroups.
If you are talking about the Portal Page Group structure, you cannot nest page groups, but you can create pages and subpages.
Hope this helps,
