switch to admin user during a workflow dinamically

[mabu_alf]

Hi. I'd like to understand if it's possible to switch to admin user during a workflow dinamically.
I'm sure that admin can perform moving or deleting action over all space.
I'd like to define something like:

step 1: user A start a workflow in his home space;
step 2: admin user (inside the workflow) moves the document to a specific space where the user B can access;
step 3: user B perform a task;
step 4: admin moves the document to original position.

I try to implement the movement but I have some problem to store the initial position of the document(package). This is the code:

…
<task-node name="tsk1">
      <task name="wf:task1" swimlane="initiator" />
      <transition name="go" to="tsk2">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            var origin = bpm_context.name;
            var dest = companyhome.childByNamePath("Intranet/SharedSpace/");
            for (var i = 0; i &lt; bpm_package.children.length; i++)
            {
               bpm_package.children[i].move(dest);
            }
         </script>
      </action>
     </transition>
   </task-node>   
   
   <task-node name="tsk2">
     <task name="wf:task2" swimlane="assignee"/>
     <transition name="finish" to="end">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
               for (var i = 0; i &lt; bpm_package.children.length; i++)
               {
                  bpm_package.children[i].move(origin);
               }
            </script>
         </action>
     </transition>
   </task-node>
…

and this is the error (initial part):

"origin" is not global?
Can anybody help me?

Thanks for any advice

"origin" is not global?

You need to pass your local script variable to the containing script context…

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
  <script>
     <expression>
       // some alfresco javascript
     </expression>
     <variable name="origin" access="write"/>
  </script>
</action>

Thank for this suggest.

I tried to adjust the code, but I don't know so much about Java Script, so I must try many times to make it work.
First test:

…
<task-node name="tsk1">
      <task name="wf:task1" swimlane="initiator" />
      <transition name="go" to="tsk2">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
         <expression>
            var origin = bpm_context.name;
            var dest = companyhome.childByNamePath("Intranet/SharedSpace/");
            for (var i = 0; i &lt; bpm_package.children.length; i++)
            {
               bpm_package.children[i].move(dest);
            }
         </expression>
         <variable name="origin" access="write"/>
         </script>
      </action>
     </transition>
   </task-node>   

   <task-node name="tsk2">
     <task name="wf:task2" swimlane="assignee"/>
     <transition name="finish" to="end">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
            <expression>
               for (var i = 0; i &lt; bpm_package.children.length; i++)
               {
                 bpm_package.children[i].move(origin);
               }
            </expression>
            </script>
         </action>
     </transition>
   </task-node>

Where is, where are the mistakes?

Can you send me a exemplifying sample code please?

Thank you so much.
