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>

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"?>

    </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">

            &lt;import resource="/Company Home/Data Dictionary/Scripts/myworflow.js"&gt;

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
