Assignee NodeRef in Workflow Email Template?

[cpaul]

Hello all,

I'm attempting to update the workflow assignment notification email so that the assignee's name is in the greeting. To do this, I will modify the "wf-email.html.ftl" template in "/Company Home/Data Dictionary/Email Templates/Workflow Notification".

I see that there is a "person" argument available that is set up by org.alfresco.repo.action.executer.MailActionExecuter.createEmailTemplateModel() (line 673). I can use this argument in the FreeMarker template to reference the assigner NodeRef properties like so:

${person.properties["cm:firstName"]} ${person.properties["cm:lastName"]}‍‍‍

I'd like to do the same thing using the assignee user NodeRef, but this doesn't appear to be available in the template. Looking at the code, it seems I'll have to extend MailActionExecuter and override the createEmailTemplateModel method so that I can inject this argument for the template, and then override the Spring bean to wire it in.

Is this the correct approach? It seems like there should be a simpler way to do this?

Thanks!
Chris

Ok, I figured out an approach that works, but am still open to anything simpler!

I extended org.alfresco.repo.notification.EMailNotificationProvider and overrode the following method:

@Overridepublic void sendNotification(NotificationContext notificationContext){   List<String> to = notificationContext.getTo();   if (to != null && to.size() == 1) {      String assignee = to.get(0);      Map<String, Serializable> args = notificationContext.getTemplateArgs();      try {         NodeRef personRef = serviceRegistry.getPersonService().getPerson(assignee, false);         args.put("assignee", new TemplateNode(personRef, serviceRegistry, null));         notificationContext.setTemplateArgs(args);      } catch (NoSuchPersonException ex) {          logger.warn("Could not find a person with the name " + assignee);      }   }   super.sendNotification(notificationContext);}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then I overrode the "emailNotificationProvider" in my custom context file, using this new class.

Finally, at the top of the wf_email.html.ftl file, I added:

<#assign assignee=args["assignee"]/>‍‍‍

Now I'm able to use the assignee user as follows:

<#if assignee?exists>${assignee.properties["cm:firstName"]} ${assignee.properties["cm:lastName"]}</#if>‍‍‍‍‍
