Hi,

my myworkflow.js contains

function myalffun(var1)
{
   return var1;
}

in one of transitions in my processdefinition.xml i included js as follows:

……
   <transition name="approve" to="l10_content_authoring" >
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            <import resource="/Company Home/Data Dictionary/Scripts/myworflow.js"/>
                                  <expression>
               logger.log(bpm_package.children[0].url);
               logger.log(myalffun('sanat'));
            </expression>
          </script>

Thanks

hi i tried executing my workflow incorporating your changes, but i am getting following error

is the logger not an javascript object? shouldnt we require logger statement to be wrapped inside <expression> tag?
like
<expression>
logger.log(bpm_package.children[0].url);
logger.log(myalffun('sanat'));
</expression>

Please suggest…

No, don't think so. Move logger code to included js function.
Paste your processdefinition, maybe that will tell us something more.

You need the expression tags, if you are using the var tags. But then, I guess, the "import" statement would need to be inside th expression tag as well.

My processdefinition.xml
<?xml version="1.0" encoding="utf-8"?>
<process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="ppdwfaypalDocumentWorkflowGroupAssignee_test">

    <task name="ppdwf:startTaskGrpAssignee" swimlane="initiator" />
   <transition name="initiate" to="review" />
</start-state>

<task-node name="review">

    </event>

    <task name="ppdwf:contentReviewerTask" swimlane="content_reviewer" />
    <transition name="approve" to="l10_content_authoring" >
      <!– Copy the content to approve folder and to l10 draft folder –>
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            <import resource="/Company Home/Data Dictionary/Scripts/myworflow.js">
            calllogger();
            logger.log(myalffun("sanat3"));

   </transition>
</task-node>

   <task-node name="l10_content_authoring">

      <transition name="taskdone" to="end" />
      <transition name="reject" to="review" />
   </task-node>

<end-state name="end" />
</process-definition>

javascript is uploaded under /Company Home/Data Dictionary/Scripts/myworflow.js
function myalffun(var1)
{
   return var1;
}

function calllogger(){
logger.log(myalffun('sanat2')+bpm_package.children[0].name);
}

Hi sanatmastan,

For your processdefinition, does having Java code in the <script> tags work? If so, where does the print lines show up?

Thanks

Hi,

The following script is not an Alfresco javascript, it is Beanshell scripting.
<script>
System.out.println("———- Process End————");
</script>

the javascript file that we including will be processed by AlfrescoJavaScript Action class, where as processing beanshell scripting is different.
<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
<script>
……..
</script>
</action>

So we can not include System.out.println in the included javascript file.
