Help needed in reading data from a Crystal Report

I am trying to read data values from a saved crystal report. (groovy code snippet below)

I open a new ReportClientDocument and set the RAS using the inprocConnectionString property.

Then I get the rowsetController and set defaultNumOfBrowsingRecords, rowsetBatchSize and maxNumOfRecords all to 1000000

Using the browseFieldValues method after that returns only 100 records. I want to get all.

    	  ReportClientDocument clientDocSaved;
	  def pathout=rc.pathToSavedReports+rr.path;
	//****** BEGIN OPEN SAVED SNAPSHOT ************

	clientDocSaved = new ReportClientDocument();
        // Open report
	println("Reading file in."), OpenReportOptions._openAsReadOnly);
       def rowsetController = clientDocSaved.getRowsetController()
	//setup metadata
	IRowsetMetaData rowsetMetaData = new RowsetMetaData()
	Fields fields =  clientDocSaved.getDataDefController().getDataDefinition().getResultFields()
	def values = rowsetController.browseFieldValues(fields.get(0), 1000000)
	   println(value.displayText(new Locale("ENGLISH")))

Before using the browseFieldValues method I was trying to use a rowsetCursor

		  //get the rowset cursor to navigate through the results
		  RowsetCursor rowsetCursor = clientDoc.getRowsetController().createCursor(null, rowsetMetaData)
		  //navigate through the rowset and log the name and value
			  Record currentRecord = rowsetCursor.getCurrentRecord()
			  //println("current record number: " + rowsetCursor.getCurrentRecordNumber())
			  for(int i=0;i<fields.size();i++){
				  //println("Column - "+fields.get(i).getName())
				  if (currentRecord.size()>0){

the currentRecord was always an empty list and I did not get any data values at all.

Am I missing something in using these approaches?

I'm fairly new to using the Java SDK for CR. Any help will be greatly appreciated.
