fProcessor.process() method stuck when PDF template with two repeating groups on same page is used.

Is it possible to use two or more repeating groups (not nestead) on same page?   

FormProcessor fProcessor = new FormProcessor();    

fProcessor.setTemplate(args[0]);  // Input File (PDF) name    

fProcessor.setData(args[1]);    // Input XML data file name    

fProcessor.setOutput(args[2]);  // Output File (PDF) name             

fProcessor.process();
