You have to turn that off first:
SpclChartResource resource = new SpclChartResource() {
/// fooo
};
resource.setCacheable(false);
Image tmpImage2 = new Image("image2", resource);

Hi,
On one page I'm displaying dynamic charts (JFreeChart) as images. The
charts, the data they're based on, are constantly changed by the users.
The problem (as I understand it): The web browser doesn't know that the
image has changed and therefore (sometimes) uses a cached image. Which
means incorrect data is displayed.
How can I make sure the browser always asks for a fresh image?
/Anders
Image tmpImage2 = new Image("image2", new SpclChartResource() {
public AbstractChartFactory getFactory() {
this.setHeight(300);
this.setWidth(600);
DefaultCategoryDatasetFactory retVal = new DefaultCategoryDatasetFactory();
retVal.setLegend(true);
retVal.setType(AbstractChartFactory.TYPE_BarChart);
