Wrong ID of Tasks

Aspose.Tasks Product Family
1

When I create children tasks, generated a wrong task ID:

public static void main(String[] args) throws IOException {
	Project project = new Project();
	project.set(Prj.DURATION_FORMAT, TimeUnitType.Hour);
	
	Task rootTask = project.getRootTask();
	
	Task a = rootTask.getChildren().add("A");
	a.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	Task b = project.getRootTask().getChildren().add("B");
	b.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	Task c = project.getRootTask().getChildren().add("C");
	c.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	Task a2 = a.getChildren().add("A2");
	a2.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	printTask(a);
	printTask(a2);
	printTask(b);
	printTask(c);
}

private static void printTask(Task task) {
	System.out.println(task.get(Tsk.ID) + " | " + task.get(Tsk.NAME) + " | " + task.get(Tsk.START) + " | " + task.get(Tsk.FINISH) + " | " + task.get(Tsk.DURATION));
}

Result:

1 | A | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
4 | A2 | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
2 | B | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
3 | C | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days

The A2 task should be 2.

Another error happens using project.recalculate():

	Project project = new Project();
	project.set(Prj.DURATION_FORMAT, TimeUnitType.Hour);
	
	project.setCalculationMode(CalculationMode.None);
	Task rootTask = project.getRootTask();
	
	Task a = rootTask.getChildren().add("A");
	a.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	Task b = project.getRootTask().getChildren().add("B");
	b.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	Task c = project.getRootTask().getChildren().add("C");
	c.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	project.setCalculationMode(CalculationMode.Automatic);
	project.recalculate();
	
	Task d = project.getRootTask().getChildren().add("D");
	c.set(Tsk.DURATION, project.getDuration(0.5d, TimeUnitType.Day));
	
	printTask(a);
	printTask(b);
	printTask(c);
	printTask(d);

Result:

1 | A | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
2 | B | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
3 | C | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 12:00:00 BRT 2020 | 0,5 days
5 | D | Wed Aug 26 08:00:00 BRT 2020 | Wed Aug 26 17:00:00 BRT 2020 | 8 hrs

The D task should be 4.
