Edgar, Search the mailing list archives for previous posts that refer to 'ApplicationContext.queueCallback(Runnable)'
apache-pivot-users.399431.n3.nabble.com apache-pivot-developers.417237.n3.nabble.com It is used to queue a Runnable to be executed on the UI thread. If wrap your call to label.setText() in a Runnable, and execute with queueCallback(), you should see the label update properly.

However, sometimes I don't see the label updating until some processing on the application is finished, is there a way to force the application to wait for the label to be updated first before trying to assign a different value to its text property? Here's some sample code: public class CountdownTask extends Task { private Label label; public CountdownTask(Label label) { this.label = label; } public void execute() { for (int i = 5; i >= 0; i--) { label.setText(i+1); Thread.sleep(1000); } } } I've tried running this both sync and async and I always get the same result. Thanks in advance, Edgar Merino
