How to retrieve all the tasks for a UserView with the worklist api 10.1.3.1

Question

Hi,
I have defined a custom view for user jcooper. The view just displays all the current uncompleted tasks for jcooper.
I want to use the worklist api to retrieve all the tasks in the view. I first tried it with the following function call:
taskQueryService.queryViewTasks(workflowContext,viewName, null, null, 0, 0);
assuming that the viewId in the corresponding java-doc corresponds to the name of the view..However this doesn't work and the method returns a null reference. So viewId is something different than a viewName. Because I cannot find the corresponding viewId for my view (not looked in the db yet, but I don't want to use these ids in my app), I tried the method:
client.getUserMetadataService().getUserTaskViewList(workflowContext, Partcipant participant);
However I did not find a method to retrieve a Partipant instance for jcooper in the worklflow api documentation.
My question now is if someone can help me out to retrieve all the tasks for a specific view. I should be possible I think...
Thanks!
Kind regards,
-Tom

The second argument (Participant) was added to handle the use case where one user such as an admin or manager needs to retrieve user metadata of another user (offcourse with the required security checks). We will try to do a future enhancement such that if the pariticipant is passed as null then we will assume the metadata is to be retrieved for the workflow context user.
For now you can define a simple method to create a participant from a workflow context as follows and pass this as an argument to the UserMetadataService call:
private Participant createParticipant(workflowContext)
Participant participant = new oracle.bpel.services.workflow.common.model.ObjectFactory().createParticipant();
participant.setName(workflowContext.getUser();
participant.setRealm("jazn.com");
participant.setType("USER");
return participant;
// code to retrieve task list...
UserViewList views = client.getUserMetadataService().getUserTaskViewList(
workflowContext, createParticipant(workflowContext))
