java sdk: reportObjectNotFound Error when trying to change connectioninfo for subreports

Hi,

we followed guidance of the sdk documentation for "To set subreport logon information". This is our code:

SubreportController subreportController = clientDoc.getSubreportController();

IStrings subReports = subreportController.querySubreportNames();

//Loop through all the subreports on main report

for (int i = 0; i < subReports.size(); i++) {

  String subreportName = subReports.getString(i);

  // the following line throws exception on each and every subreport: com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: Berichtobjekt kann nicht gefunden werden.---- Error code:-2147213285 [CRSDK00000685] Error code name:reportObjectNotFound

  IDatabase subreportDatabase = subreportController.getSubreportDatabase(subreportName);

  tables = subreportDatabase.getTables();

  for (int j = 0; j < tables.size(); j++) {

    Table oldTable = (Table) tables.getTable(j);

    Table newTable = changeTableInfo(oldTable, logonPb, reportConfig);

    subreportController.setTableLocation(subreportName, oldTable, newTable);

  }

}

This worked for cr 2008 sdk but stopped working with cr 2013 sdk. Are there any changes in handling subreports with the new sdk?
