          Show us the view that calls startTaskA(). Does it pass a taskId parameter?

              Gavin King Master

              Huh?? I am expecting to see a valuebinding with #{taskWorkflow.startTaskA}

              Have you looked at the examples of this stuff?

                  You are not passing a taskId. You are not even in a task list!

                  Go and read the documentation and look at the example applications. I don't know what you're trying to do here, but it has nothing to do with @StartTask.

                    well, i went to read the documentation and the examples ( jejejeje ).
                    now, i show one "startTask" button for each taskInstance of the process.
                    the problem now is that i get nothing in the taskInstanceList, but i create the process instances in the CreateTask.xhtml.
                    maybe i'm forgetting any tag or annotation.
                    Any ideas?

                      Juan Giovanolli Newbie

                      i'm basing my example in the todo example of jboss seam. it's very simple, and is almost equals to that, but in's not working for any reason.
                      the unique difference that i can found is that my app doesn´t include the login part of the todo example.
                      Any ideas.
                      Thanks

                        Without the login, how do you set the Actor (user) that you are getting tasks for?

                          Right, as per the docs, you need a defined actor id if you expect to find any tasks have been assigned to you.
