XI R2 Webi Ranking with the SDK

Question

Hi all,
Using the default universe eFashion I get an java.lang.UnsupportedOperationException.
The code is very simple (attached to the message).
private static void addRankCondition(DocumentInstance iDocInstance, Podium iPodium, int iSize,
          String iFilteredDimension, String iBasedOnMeasure) {
     DataProviders lDataProviders = iDocInstance.getDataProviders();
     DataProvider lDataProvider = lDataProviders.getItem(0);
     DataSource lDataSource = lDataProvider.getDataSource();
     if (!lDataSource.isRankConditionSupported()) {
          throw new AuiException("Data source does not support ranking.");
     DataSourceObject lFilteredDimension = lDataSource.getClasses().getChildByName(iFilteredDimension);
     DataSourceObject lBasedOnMeasure = lDataSource.getClasses().getChildByName (iBasedOnMeasure);
     Query q = lDataProvider.getQuery();
     ConditionContainer lConditionCont = q.createCondition(LogicalOperator.AND);
     lConditionCont.createRankCondition(iPodium, iSize, lBasedOnMeasure, lFilteredDimension);
     lDataProvider.runQuery();
- Is there any example on the Ranking feature?
- Is there any documentation on the possible restrictions?
Please keep in mind that I am using XI R2 and not 3.0. The code doesn't work with document using eFashion eventough it works on Infoview.
Thanks a lot for any input.
David
