I don't know if that helps with your problem, but you could leave the
events as they are today and only make new requests to the server when the
previous one were executed.
Something like this:
private boolean requestingServer = false;
public void onScroll(ScrollEvent scrollEvent) {
if (requestingServer) return;
requestingServer = true;
doServerRequest(new Callback(){ //pseudo code here for a callback
mechanism
public void onResponse(Payload something){
requestingServer = false;
}
});
}
You can add a logic for a minimum delay between requests as well.
This kind of code works on GWT because it is single threaded. In pure Java
you would need to create synchronized blocks to ensure that only one
request is being made to the server.
