Dynamically updating a job status

Question

I have a scenario where a job unzips a zip file and if there are images in the file it goes one path and if there aren't it goes another path.  It works fine if there are images as that path runs all of the jobs in the job group and the job group resets to Waiting on Children and all children reset to Waiting on Dependencies because it is scheduled to run the same occurrence every five minutes.  When there aren't images, it runs a nested job group to clean up the zip file and directory it created but leaves several of the jobs in a Waiting on Dependencies status so another occurrence never fires off.  I would like to update all of the jobs that are stuck in the Waiting on Dependencies status to a Completed Normally status when that nested job group completes normally, but I am not sure how to control the status on these jobs dynamically.  Any suggestions would be very much appreciated.

Perhaps this sample code may help you.
import javafx.animation.*;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.event.*;
import javafx.scene.*;
import javafx.scene.chart.*;
import javafx.stage.Stage;
import javafx.util.Duration;
public class VaryingChart extends Application {
  public static void main(String[] args) { launch(args); }
  @Override public void start(Stage stage) {
    final NumberAxis xAxis = new NumberAxis();
    final AreaChart chart = new AreaChart(
      xAxis, new NumberAxis(),
      FXCollections.observableArrayList(
         new XYChart.Series("April", FXCollections.observableArrayList(
           new XYChart.Data(0, 4), new XYChart.Data(1, 10), new XYChart.Data(2, 18)
         new XYChart.Series("May", FXCollections.observableArrayList(
           new XYChart.Data(0, 20), new XYChart.Data(1, 15), new XYChart.Data(2, 12)
    xAxis.setAutoRanging(false);
    xAxis.setUpperBound(3);
    chart.setTitle("Temperature Monitoring (in Degrees C)");
    stage.setScene(new Scene(chart, 800, 600));
    stage.show();
    Timeline t = new Timeline(new KeyFrame(Duration.seconds(1), new EventHandler<ActionEvent>() {
      @Override public void handle(ActionEvent arg0) {
        xAxis.setLowerBound(xAxis.getLowerBound() - 1);
    t.setCycleCount(Timeline.INDEFINITE);
    t.play();
}Here is another example of displaying data dynamically on a chart: https://gist.github.com/2129306
I have never found a situation where you needed to explicitly call
dynamicChartPane.requestLayout() or chart.needsLayout()
