you shouldnt have requests that take a long time to process. there are
lots of problems with this like users starving your threadpool, etc.
instead you should load the data in another thread and either use a
push notification or let the client poll to find out if the data is
available.
unfortunately the ajaxlazyloadpanel is not implemented correctly, it
doesnt poll but simply request and wait for the data with ajax.
a better implementation might look like this and might better work for
what you need:
class BetterLazyLoadPanel extends Panel {
public BetterLazyLoadPanel() {
add(new WebMarkupContainer("content")); <-- placeholder until
the right component is added
add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(2)) {
onTimer(target) {
Component replacement=getLazyLoadedComponent("content");
if (replacement!=null) {
replace(replacement);
stop();
target.add(BetterLazyLoadPanel.this);
}
}
});
}
protected abstract getLazyLoadedComponent(String id);
}
now in getLazyLoadedComponent() you can return null until your data
has finished loading in another thread, and when its done return the
component you wish to represent it with. hope this helps.
