Error : ReferenceError: 'companyhome' is not defined.

nitinkcv — Tue, 03 Nov 2009 13:27:47 GMT

Hi,I'm actually trying to trigger a mail using the AlfrescoJavascript.Part of my code in the process definition file is:<transition name="moreInfoNeeded" to="moreInfoNeeded" > <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript"> <script>

Re: Error : ReferenceError: 'companyhome' is not defined.

nitinkcv — Tue, 03 Nov 2009 13:43:46 GMT

I got the solution for the error.

I need to add a statement like:


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

which should be just before the <expression> tag. However now the problem comes to the ftl. It gives an error saying that

Caused by: freemarker.core.InvalidReferenceException: Expression url is undefined on line 4, column 24 in workspace://SpacesStore/2005cd22-e18f-4112-8442-e0a8558725c0.

BUt isnt the url attribute a keyword in ftl?

Re: Error : ReferenceError: 'companyhome' is not defined.

it depends on the context of the FTL.
If your ftl is a presentation template in alfresco, yes.
If it's in the body of a mail, no.
you have to provide it yourself to the Freemarker model when building the email

Hi,

Are there any examples or links that you have come across that i could follow to do this?

Thanks.

Hi, someone faced the same troubles a few weeks ago.
It seems that he could manage to achieve what you are up to :

JayJayEcl,

With respect to the post that you wriiten @ http://forums.alfresco.com/en/viewtopic.php?f=34&t=22202, youve said to modify the MailActionExecuter code to include the models.

The url for the tasks would be of the form http://localhost:8080/alfresco/command/ui/managetask?id=jbpm$2&type=${pooled.qnameType}&container=plain. I tried to debug the MailActionExecuter class. However i was not find out the values for the 'id=jbpm$2' and 'type=${pooled.qnameType}' from any of the variables that are declared there in the class. I'm assuming that these values need to be put in the model which can be made use in the ftl.

Do you have any pointers regarding getting these?

Also in the post @ http://forums.alfresco.com/en/viewtopic.php?f=34&t=14595&p=75219#p55772 a piece of method is written however not sure whether its a overriden method or which class its from?

Thanks.

Re: Error : ReferenceError: 'companyhome' is not defined.

jayjayecl — Wed, 04 Nov 2009 16:15:58 GMT

the piece of method is from custom code.

However i was not find out the values for the 'id=jbpm$2' and 'type=${pooled.qnameType}' from any of the variables that are declared there in the class. I'm assuming that these values need to be put in the model which can be made use in the ftl

If you fork (rewrite) MailActionExecuter, you'll be able to add new parameters to the action, including passing (via scripting in the processDefinition.xml) new vars -such as taskID and taskType- to the action… and then handle them so that they are available in the model for the ftl template

JayJayECL,

In the MailActionExecutor the only two param that it takes are the Action and NodeRef. Do you have any examples as to how to pass var like the taskID and TaskType to the Action from my script in the process definition file?

Currently i'm building up my task URL in the processDefinition file. Something like this:


<task name="ppdwf:contentAuthorTask"  swimlane="content_author" >
         <event type="task-create">
                <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                  <script>
                     executionContext.setVariable("taskInstanceID", taskInstance.id);
                     executionContext.setVariable("taskInstanceName", taskInstance.name);
                  </script>
                </action>             
         </event>
      </task>
      <transition name="moreInfoNeeded" to="moreInfoNeeded" >
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
                <variable name="bpm_package" access="read" /> 
                <variable name="initiator" access="read" />
                <variable name="bpm_workflowDescription" access="read" />
                <variable name="companyhome" access="read"></variable>
                <variable name="taskInstance" access="read" />
                <expression>
                     var mail = actions.create("mail");
                     var prsn = initiator;
                     try {
                        var emailAddress = prsn.properties.email;
       var taskType = executionContext.getVariable("taskInstanceName").substring(executionContext.getVariable("taskInstanceName").indexOf(":")+1);
                        var taskURL = "http://localhost:8080/alfresco/command/ui/managetask?id=jbpm$" + executionContext.getVariable("taskInstanceID") + "&amp;type={com.pixs.workflowuri}" + taskType + "&amp;container=plain";
                        mail.parameters.to = emailAddress;
                        mail.parameters.subject = "Content authoring task submitted with additional information";
                        mail.parameters.from = person.properties.email;
                        mail.parameters.template = companyhome.childByNamePath("Data Dictionary/Email Templates/notify_user_email_taskurl.ftl");                        
                        mail.parameters.text = "Default text goes here. Please click on" + taskURL  + " to go to the task";
                        mail.execute(bpm_package);
                        logger.log("send mail to "+ prsn.properties.userName + "taskURL: " + taskURL);
                     } catch (error) {
                        logger.log("Failed sending mail to "+ prsn.properties.userName + "taskURL: " + taskURL + "  " + error);
                     }
               </expression>   
             </script>
         </action>
      </transition>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But i would like to make use of a ftl template. Also rather hardcoding the workflowURI it would be nice to get it from some variable.

Thanks.

Re: Error : ReferenceError: 'companyhome' is not defined.

nitinkcv — Mon, 09 Nov 2009 19:54:57 GMT

Found out a way to pass parameters i think.
Page @ http://wiki.alfresco.com/wiki/3.1_JavaScript_API#ScriptAction_API mentions that

parameters
an associative array (map) of the parameters for the action. For example mail.parameters.subject. Each parameter is keyed by a String. Parameters can be modified and new parameters added.

So what i'm hoping is that i can add new parameters to the mail. So inside my process definition file i'm adding something like"


mail.parameters.taskid = executionContext.getVariable("taskInstanceID");
mail.parameters.tasktype = executionContext.getVariable("taskInstanceName");                        
‍‍‍‍

And i'm modifying the MailActionExecter class:


      // add objects for the taskid, taskName and the url for the taskInstance related information
      model.put("taskInstanceObj", obj);
‍‍‍‍

where my obj is a java class which has the taskURL as one of its member variables.

My ftl is of the form:


New task has been created. Please click on ${taskInstanceObj.taskURL} to view the task.
‍‍‍

I have re-jar the alfresco-repository.jar with these two java classes(MailActionExecuter and TaskInstanceObject).

However on server start i get the following exception:

Hi
When I send emails with attachments from Jbpm first of all I had to implement an extension to the EmailActionExecuter to handle attachments (this is covered in http://forums.alfresco.com/en/viewtopic.php?p=51285). Then you have to pass on any attachment as a parameter to the extended EmailActionExecuter like:


final Action mailAction = actionService.createAction(AttachmentEmailerActionExecuter.NAME);
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_SUBJECT, properties.get(MailProperty.SUBJECT));        
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TO, properties.get(MailProperty.TO_ADDRESS));
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_FROM, properties.get(MailProperty.FROM_ADDRESS));
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TEXT, properties.get(MailProperty.BODY));
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TEMPLATE, properties.get(MailProperty.TEMPLATE));
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_ATTACHMENTS, attachments);
        mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_MODEL, model);
        actionService.executeAction(mailAction, null);
‍‍‍‍‍‍‍‍‍‍‍

The attachements are a List<NodeRef> in this case, but it depends on how you choose to extend EmailActionExecuter.

Finally I have implemented my own JBPMAction to send the emails, like:


public class SendExternalConfirmation extends JBPMSpringActionHandler {

   private static final Logger logger = Logger.getLogger(SendExternalConfirmation.class);
   
   private static final long serialVersionUID = 343656888342953693L;

   private static final String INITIATOR_EMAIL_PROCESS_VARIABLE = "initiatorEmail";
   private static final String ATTACHMENT_NODEREF_PROCESS_VARIABLE = "a_nodeRef";
         
   
   //—————————————————
   //Public methods
   //—————————————————
   public void execute(final ExecutionContext context) throws Exception {
      final String initiatorEmail = (String) context.getVariable(INITIATOR_EMAIL_PROCESS_VARIABLE);
      final JBPMNode attachmentNode = (JBPMNode)context.getVariable(ATTACHMENT_NODEREF_PROCESS_VARIABLE);

      final ArrayList<NodeRef> attachedDocuments = new ArrayList<NodeRef>();
      attachedDocuments.add(attachmentNode.getNodeRef());
               
      final Action mailAction = actionService.createAction(AttachmentEmailerActionExecuter.NAME);
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_SUBJECT, "Test subject"));        
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TO, initiatorEmail);
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_FROM, "noreply@alfresco.com");
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TEXT, "bla bla");
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_TEMPLATE, "if use freemarker put a template here…");
      mailAction.setParameterValue(AttachmentEmailerActionExecuter.PARAM_ATTACHMENTS, attachedDocuments);
      mailAction.setParameterValue(TransmittalAttachmentEmailerActionExecuter.PARAM_MODEL, model);
        
      actionService.executeAction(mailAction, null);
   
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You the call your own action from the JBPM processdefinition. Like


<event type="node-enter">
   <action class="com.mycompany.SendExternalConfirmation"/>
</event>
‍‍‍‍‍

Of course the attachments and email address must have been set in the workflow previously for this to work.

Hi all,

Thanks for all your help.
I'm able to send the task url in the body of the mail. I'm making use of an email template(.ftl file).

I guess the exceptions that i got were because the jar file that i created got corrupted somehow. I made use of the jar cvf to pack the jar up which worked perfectly.

Like JayJayECL mentioned, i had to pass my taskid and tasktype on to the Action. The MailActionExecuter class had to be tweeked to handle the newly passed params and to add it as part of the ftl model.

Thanks.

And I have extended the MailActionExecuter.java
Here is the code snippet from extended java.

public static class TaskHelper
    {
        String taskId;
        
        public String getTaskId()

      NodeRef person = personService.getPerson(authService.getCurrentUserName());
      model.put("person", new TemplateNode(person, serviceRegistry, null));
      model.put("document", new TemplateNode(ref, serviceRegistry, null));
      NodeRef parent = serviceRegistry.getNodeService().getPrimaryParent(ref).getParentRef();
      model.put("space", new TemplateNode(parent, serviceRegistry, null));
      
      // current date/time is useful to have and isn't supplied by FreeMarker by default
      model.put("date", new Date());
      
      // add custom method objects
      model.put("hasAspect", new HasAspectMethod());
      model.put("message", new I18NMessageMethod());
      model.put("dateCompare", new DateCompareMethod());
      model.put("url", new URLHelper(repoRemoteUrl));
      model.put("task", new TaskHelper());
      return model;
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But still I can't access the task variable in my ftl.
I am getting an error saying that task variable is undefined.

please help!!

Thanks
Sans!!
