When I end a workflow through workflow.cancel() or workflow["delete"](); I can't access the documents' parrent space in Share afterwards.I tried searching the forums, but couldn't find any similar problem.So the details: I upload a file to a space in document library and start an advanced workflow w

And another, even better question, that would actually help me solve the issue. Could somebody post an example of how to get the list of possible transitions for a task and then send the document down one of these?

Zladuric,

I can't help you with the cancel workflow issue as I'm trying to figure that out myself (though for cleaning up a development environment, not how you appear to be using it). I can help you with your last question. However, it's unclear if you really want the transitions for a random document's task, or if you want the transitions for tasks that the user has in My Tasks. So, I'll answer both questions.

First, here is some FTL for showing the tasks in My Tasks and the transitions for each task:

 <table cellspacing=0 cellpadding=2>
   <tr>
      <th>ID</th>
      <th>Type</th>
      <th>Name</th>
      <th>Completed</th>
      <th>Transitions</th>
   </tr>
   <tr>
     <td colspan="11"><hr/></td>
   </tr>
   <#list workflow.assignedTasks as t>
      <tr>
         <td>${t.id}</td>
         <td>${t.type}</td>
         <td>${t.name}</td>
         <td>${t.isCompleted?string("Yes", "No")}</td>
         <td>
            <#list t.transitions as transition>
                <span class="${t.id} ${transition.id}">
                  ${transition.label?html}
                </span>
                <#if transition_has_next><span class="separator">|</span></#if>
            </#list>
         </td>
      </tr>
   </#list>
 </table>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But let's say you are starting with a document nodeRef. Here is how you would find all of the workflows, tasks, and transitions connected to that document, and then how you would transition one of them (leaving for homework how you would choose which one to transition):


var theDocument = search.findNode(docNodeRef);
var tasks = [];

// get the current task IDs and push them into the tasks array
for each (wf in theDocument.activeWorkflows)
  {
    var thePaths = wf.getPaths();
    for (var pathKey in thePaths)
      {
        var theTasks = thePaths[pathKey].getTasks();
        for (var taskKey in theTasks)
          {
            tasks.push(workflow.getTaskById(theTasks[taskKey].getId()));
          }
      }
  }

// Now that we have the tasks for all workflows attached to the current document
// you can get the possible transitions this way.
var transitions = {};
for (var key in tasks)
  {
    var taskTransitions = tasks[key].getTransitions();
    for (var key1 in taskTransitions)
      {
        transitions[tasks[key].getId()] = taskTransitions[key1].getId();
      }
  }

// Now that you have the transitions you can display them for
// your user but to transition one of these you do something like
// this.

var task = workflow.getTaskById(taskId);
task.endTask(transitionId);
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I hope this helps.

Oh, thanks very very much for your effort. I found it out myself in the mean time, so it doesn't matter any more. Thanks for the help again anyway.
