How to set a property before workflow transition

sgartner — Fri, 18 Jun 2010 10:06:35 GMT

I have a workflow in state A and I need to transition it to state B in JavaScript when a user does something in my application. In order to transition to state B I need to set the due date that they have to complete B by. I figured I would just set bpm:workflowDueDate to today + 7 days, but I can'

Well, I thought I had found a solution. Task has a getProperties() method and an undocumented setProperties() method. I had hoped that if I called getProperties and modified the results I could then put them back in using setProperties before transitioning. This does not work:


    var taskId = args["taskId"];
    var transitionId = args["transitionId"];
    var task = workflow.getTaskById(taskId);
    var futureDate = new Date();
    futureDate.setDate(futureDate.getDate() + 7);

    // This does *not* work, unfortunately
    var workflowProperties = task.getProperties();
    workflowProperties["bpm:workflowDueDate"] = futureDate;
    task.setProperties(workflowProperties);

    task.endTask(transitionId);

Crap, according to this thread:
http://forums.alfresco.com/en/viewtopic.php?f=34&t=27349&p=89543&hilit=javascript+workflow+properties#p89543

Apparently Alfresco neglected to implement this vital component. This means that only trivial workflows can be transitioned via JavaScript.

Well, I figured out why the undocumented setProperties() function doesn’t work (and maybe why it’s undocumented). The JscriptWorkflowTask class copies the properties from the task into the JScript object, and so when you do getProperties() it gives you back that copy. When you do setProperties() it updates the copy but never reflects that back to the workflow. Pretty pointless.

In the code below…where/how are you getting the transitionid? How are you populating this in the previous step? I can't seem to bring any value to this webscript that is actually the transitionid for an adhoc workflow. I'm stuck here!


var transitionId = args["transitionId"];
var task = workflow.getTaskById(taskId);
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 7);

Help?

Fordville,

I don't know if this will help, but here is a test script of mine that passes, among other things, transition IDs to a test script (with code similar to the above). I am involved on a different project at the moment, so I can't test it, but I assume this script works.

listTasks.get.html.ftl:


My Tasks Todo:
 <table cellspacing=0 cellpadding=2>
   <tr>
      <th>ID</th>
      <th>Type</th>
      <th>Name</th>
      <th>Created Date</th>
      <th>Due Date</th>
      <th>Priority</th>
      <th>% Complete</th>
      <th>Status</th>
      <th>Completed</th>
      <th>Transitions</th>
   </tr>
   <tr>
     <td colspan="11"><hr/></td>
   </tr>
   <#list workflow.assignedTasks as t>
      <tr>
         <td><a href="/alfresco/wcs/GreatApp/workflow/actionList?taskId=${t.id?html}">${t.id}</a></td>
         <td>${t.type}</td>
         <td>${t.name}</td>
         <td>${t.properties["cm:created"]?datetime}</td>
         <td><#if t.properties["bpm:dueDate"]?exists>${t.properties["bpm:dueDate"]?datetime}<#else><i>None</i></#if></td>
         <td>${t.properties["bpm:priority"]}</td>
         <td>${t.properties["bpm:percentComplete"]}</td>
         <td>${t.properties["bpm:status"]}</td>
         <td>${t.isCompleted?string("Yes", "No")}</td>
         <td>
            <#list t.transitions as transition>
                <#if !transition.label?contains(":internal")>
                    <span class="${t.id} ${transition.id}">
                      <a href="http://localhost:8080/alfresco/wcs/GreatApp/workflow/form?taskId=${t.id}&transitionId=${transition.label?html}&debug=1">
                        ${transition.label?html}
                      </a>
                    </span>
                    <#if transition_has_next><span class="separator">|</span></#if>
                </#if>
            </#list>
         </td>
      </tr>
   </#list>
 </table>
