WebComponent was a perfect fit, thank you.
A somewhat related problem exists however.
I load this Image using AjaxLazyLoadPanel like so:
add(new AjaxLazyLoadPanel("image") {
/**
* Makes object serializable.
*/
private static final long serialVersionUID = 1L;
@Override
public Component getLazyLoadComponent(String id) {
return (new ChartPanel(id));
}
});
class ChartPanel extends Panel {
private static final long serialVersionUID = 1L;
/**
* Constructor for ChartPanel.
*
* @param - The id to use
*
*/
public ChartPanel(String id) {
super(id);
addChart(this);
}
which calls my the addChart() that works now since I switched to WebComponent.
The lazy loading image (the spinning waiter) continues to spin after
the image is loaded.
Am I missing something obvious here to make it stop?
Thanks
