JFreeChart graphics with image map

[syphinx]

Hi

I create dynamic images with JFreeChart. It works great.

Now I want to add image map to the charts. I can generate the map string at backing bean but cannot pass it to view. Becuase it is generated at the second request which image is generated.

Code: Select all

public class HistogramBean {
         
        private StreamedContent chart;
	private String imageMap;

        public HistogramBean() { 
                
                FreeChart jFreeChart = .......;
	        File chartFile = new File (.........);
        	ChartRenderingInfo info = new ChartRenderingInfo(........);
	        ChartUtilities.saveChartAsPNG(....................... , info);
        	chart = new DefaultStreamedContent(.......................);
        	imageMap = ImageMapUtilities.getImageMap(....................);
                logger.debug(imageMap);
        }

imageMap string is logged correctly. But it is empty at view side, since it is generated at the second request.

How can I get the generated string correctly?

Thanks,
