Generic task manipulation is supported through the tasks API. Take a look at the org.eclipse.mylyn.examples.bugzilla plug-in for instance: http://wiki.eclipse.org/Mylyn_Integrator_Reference#Quick_Example .

Manipulation of contexts is currently not directly supported though API. It would be great if you could add your specific requirements for the context API to bug 242428 so we can consider adding that for a future release.

Bug 204495 might actually be the better fit to track these requirements.

Steffen, according to the original ticket description from Lars, the requested API was not just a public context API, but also public API for task creation/deletion etc. as well. In your initial comment you referred to the example but as far as I can see it does not cover the generic (connector independent) creation of a task and I'm still not sure about the official way to do it. Any hint or an updated example is highly appreciated.

It depends on the context. For standalone use this is a basic example for creating a task:

		// create task repository
		TaskRepository repository = new TaskRepository(TracCorePlugin.CONNECTOR_KIND, URL);

		// create connector
		TracRepositoryConnector connector = new TracRepositoryConnector();

		// initialize task data
		TaskAttributeMapper attributeMapper = connector.getTaskDataHandler().getAttributeMapper(repository);
		TaskData taskData = new TaskData(attributeMapper, repository.getConnectorKind(), repository.getRepositoryUrl(),
				"");
		connector.getTaskDataHandler().initializeTaskData(repository, taskData, null, new NullProgressMonitor());

		// set attributes
		TaskMapper mapping = connector.getTaskMapping(taskData);
		mapping.setSummary("new task");
		mapping.setDescription("Task created.");

		// submit task
		RepositoryResponse response = connector.getTaskDataHandler().postTaskData(repository, taskData, null,
				new NullProgressMonitor());

		String taskUrl = connector.getTaskUrl(repository.getRepositoryUrl(), response.getTaskId());
		System.out.println(MessageFormat.format("Task ''{0}'' created at {1}", response.getTaskId(), taskUrl));

If you are looking for an example how to do this when running the Mylyn UI, I would recommend looking at NewTaskFromJunitResultViewAction for instance:

		TaskMapping taskMapping = new TaskMapping() {
			@Override
			public String getDescription() {
				return "New Task";
			}
		};
		TasksUiUtil.openNewTaskEditor(shell, taskMapping, null);

My context is definitely this one. Tasks are derived from other work in the eclipse environment and should be semi-automatically created, optionally immediately submitted and visible in the task list so thanks for the code.

I used a lot of internal API so far (for example TasksUiInternal.createTaskData) that more or less does the things as you have pointed them out in the sample code. But I want to go "official" and therefore asked the question.

Thanks Jan
