Jasper Reports 3.1.7 to 4.50 , changes with JasperDesign.getDetail

[sangeethakrishna]

Hi ,

We are upgrading jasper reports 3.1.7 to 4.5.0. 

JasperDesign.getDetail

Code with Previous version: 

private JRDesignBand findBandForSubReport(JasperDesignBuilder jasperDesignBuilder, SubReport subReport) throws Exception
    {
                          return (JRDesignBand) jasperDesign.getDetail();
     }

Change i have done with 4.5.0:

 private JRDesignBand findBandForSubReport(JasperDesignBuilder jasperDesignBuilder, SubReport subReport) throws Exception
    {
            JRDesignSection jrDesignSection = (JRDesignSection)jasperDesign.getDetailSection();
            for(JRBand jrBand : jrDesignSection.getBands())
             {
                 if(jrBand instanceof JRDesignBand)
                 {
                     return (JRDesignBand)jrBand;
                 }
             }
     }

We are using same code for getHeaderSection, getFooterSection also.

Please check the code above, let me know is that the correct way of getting JRDesignBand  from JRDesignSection.
