How to find current workflow user? [SOLVED]

[jimcornmell]

Hi All,

Again help in advance.

Within my process definition I have the following task.  In it I'm trying to find the current user who kicks of the "Send to Artist" transition.

<task-node name="Waiting for Artist">   <task name="wf:waitingForArtistTask" swimlane="artistsPool" />   <transition name="Send to Artist" to="Create">      <script>         <variable name="wf_reader" access="write" />         <variable name="bpm_assignee" access="read" />         <expression>            wf_reader = "New reader = " + bpm_assignee;         </expression>      </script>   </transition></task-node>‍‍‍‍‍‍‍‍‍‍‍‍

I've tried the above but I get null for bpm_assignee.  I've deliberately ignored initiator although I get a value for this the wiki states this is "the person who initiated the workflow", and I don't need that information.

My question is: Which variable do I need to access to find the current user?

YOu could use the "variable" person to access the current user performing an action!
For instance:

person.properties.userName

would return the user name of the current user.
In your case you have probably add also

<variable name="person" access="read"/>‍

to your script.

Good luck. Rob

Hi rob,

I've tried the following:

<task-node name="Waiting for Artist">   <task name="wf:waitingForArtistTask" swimlane="artistsPool" />   <transition name="Send to Artist" to="Create">      <script>         <variable name="wf_reader" access="read,write" />         <variable name="person" access="read" />         <expression>            wf_reader = "new reader = " + person.properties.userName;         </expression>      </script>   </transition></task-node>‍‍‍‍‍‍‍‍‍‍‍‍

But all I get is a null pointer exception.  Looking more closely person is null.  Do I need to add this to my aspect?  Or how do I inherit it?

Hi Jim,

I think the problem is that you are using "Java" and not "JavaScript"

Here is an example of some code I use:

  <transition name="Continue" to="createCcr">   <condition>#{!qcp_wfIssueExist}</condition>   <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">    <script>     var logDateTime = new Date();     var ccrLogFile = companyhome.childByNamePath("CCR repository/Log files/" + qcp_wfCcrNr + ".log");     if (ccrLogFile != null)     {      var logLine = logDateTime.getFullYear() + ";" + utils.pad(logDateTime.getMonth()+1,2) + ";" + utils.pad(logDateTime.getDate(),2);      logLine += ";" + utils.pad(logDateTime.getHours(),2) + ";" + utils.pad(logDateTime.getMinutes(),2) + ";" + utils.pad(logDateTime.getSeconds(),2);      logLine += ";" + utils.pad(logDateTime.getTime(),16);      logLine += ";" + qcp_wfCcrNr;      logLine += ";" + person.properties.userName + ";" + "" + ";" + qcp_wfCycleNr;      logLine += ";" + "Issue number checked and found unique";      logLine += ";" + bpm_package.children[0].properties["qcp:previousWorkflowStatus"];      logLine += ";" + bpm_package.children[0].properties["qcp:currentWorkflowStatus"];      ccrLogFile.content += logLine + "\r\n";     }     bpm_package.children[0].properties["qcp:previousWorkflowStatus"] = "qcp:mayCreateCcr";     bpm_package.children[0].save();     if (bpm_package.children.length &gt; 1)      for (var i = 1; i &lt; bpm_package.children.length; i++)       if (bpm_package.children[i].parent.properties.name != bpm_package.children[0].parent.properties.name)       {        var newCopy = bpm_package.children[i].copy(bpm_package.children[0].parent);        bpm_package.removeNode(bpm_package.children[i]);        bpm_package.addNode(newCopy);       }    </script>   </action>  </transition>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

So you might try to add

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">

and

</action>

around your script.
As you can see I did not use the

<variable

and

<expression

tags but that would not be the problem I guess.

Success,
Regards, Rob

SOLVED: MANY MANY thanks rob, I just needed the right combination.  The following works.  It has a bit of a red herring because the various error messages did not relate to their being a problem with the tagging….

<task-node name="Waiting for Artist">   <task name="wf:waitingForArtistTask" swimlane="artistsPool" />   <transition name="Send to Artist" to="Create">      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">         <script>            <variable name="wf_reader" access="read,write" />            <expression>               wf_reader = person.properties.userName;            </expression>         </script>      </action>   </transition></task-node>‍‍‍‍‍‍‍‍‍‍‍‍‍
