RE: [mylyn-integrators] How to get TaskData? 
Thanks alot Rob.

In the wait for the answer, I did the following:

In updateTaskFromTaskData(repository, task, taskData), I created an AbstractTask of this task and set the secheduledForDate, estimatedTimeHours and notes and this made the data show on the taskEditor and be update-able. Even though this solved my problem I did not feel that that was they way this was intended to be done. First because I had to use an internal class and second because I could set the DueDate through the TaskMapper. So my updateTaskFromTaskData() looks as follows:

@Override
public void updateTaskFromTaskData(TaskRepository repository, ITask task, TaskData taskData) {
       TaskMapper mapper = new TaskMapper(taskData);
       mapper.setDescription(taskData.getRoot().getAttribute(DESCRIPTION).getValue());
       mapper.setDueDate(extractTime(taskData.getRoot().getAttribute(DUE_DATE).getValue()));
       mapper.applyTo(task);

      // TODO Find a substitute for using AbstractTask
       AbstractTask aTask = (AbstractTask) task;
       aTask.setEstimatedTimeHours(taskData.getRoot().getAttribute(ESTIMATED_HOURS).getValue());
       aTask.setNotes(taskData.getRoot().getAttribute(DESCRIPTION).getValue());
       aTask.setScheduledForDate(taskData.getRoot().getAttribute(SCHEDULED_FOR_DATE).getValue());
}

I checked TaskEditorPlanningPart and it looks to me that it is using a similar way, aka it sets the data in an AbstractTask-version of the task through TasksUiPlugin.getTaskActivityManager() which HAS TO take an AbstractTask as a parameter. So if I use the same way and since TasksUiPlugin itself is an internal class, I end up using 2 internal classes instead of one, which feels even more wrong.

Am I missing something? Or this is actually the only way to go?

Best regards,
Avin

Hi Avin,

Have a look at TaskEditorPlanningPart to get an idea for how these
fields are accessed and manipulated. Some of these fields are internal
so you may need to break some 'rules' to manipulate them. In these
cases, look for an existing api bug or create a new one, to address your
specific needs.
