It will be hard to offer any advice on this without a test case.

But, the message you are getting is typically thrown if you have not actually "started" the task.

A typical usage scenario might look like this:

1st unit of work ("process instantiation"):

conversation.begin();
...
businessProcess.setVariable("billingId", "1"); // setting variables before starting the process
businessProcess.startProcessByKey("billingProcess");
conversation.end();

2nd unit of work ("perform a user task"):

conversation.begin();
businessProcess.startTask(id); // now we have associated a task with the current conversation
... // this allows us to retrieve and change process variables
// and @BusinessProcessScoped beans
businessProcess.setVariable("billingDetails", "someValue"); // these changes are cached in the conversation
...
businessProcess.completeTask(); // now all changed process variables are flushed
conversation.end();

Notice, startTask() is called before completing the task.

Hope this helps,

Greg

I would attach a breakpoint to the startTask() method and make sure it is actually being called with the correct taskId from your preRender listener.
