Camunda jump to next user task

Question

I am attempting to string tasks together, I am able to get the task ID of the next user task by running the following in a TaskListener Create script:

var system = java.lang.System;
system.out.println(task.id);

Which returns the correct id.

I would then like to update the url in the browser to "ip:port/camunda/app/tasklist/default/#/?task=" + task.id

But because the TaskListener Create script is not running in the browser itself (not sure why to be honest), I don't have 'window.location' available.

Is there a simple solution to this?

Answer 1

For anyone interested we found a solution.

We use the REST api's GET task command, the code looks like this

camForm.on('submit-success', function() {
inject(['$rootScope', function($rootScope) {
  var user = $rootScope.authentication.name;
  setTimeout(function(){  
    $.get("/engine-rest/task?sortBy=created&sortOrder=desc&assignee=" + user, function(data) {
      window.location.replace("http://is-company.intelligentsystems.lan:8080/camunda/app/tasklist/default/#/?task="+ data[0].id);
   });
  }, 300);
}]);
});

This code is called when you press start/complete on a task, and the processing is successful (submit-success), then it finds the current user, and searches for the newest task assigned to the user and sets it in the url using window.location.replace We had the issue that the task is not completely created when the code is run immediately, but adding a small delay of 300 (could be smaller, but better safe than sorry) before getting the task id.

Answer 2

Any script that you add to your process model is executed on server side (including task listeners), unless it belongs to a task form.

The task object is an instance of the Java class org.camunda.bpm.engine.delegate.DelegateTask. You can skip the current task by writing task.complete().
