In a Kaleo workflow definition, you can have email notifications.

Currently, you can have variables in the body of the email notification, but you can not add variables to the subject/description field of an email notification.

It is a simple change to allow variables in the subject/description field for email notifications of workflow definition. Paul Shemansky contributed this while working on workflow definitions for Liferay Foundation.

In plugins / webs / kaleo-web / docroot / WEB-INF / src / com / liferay / portal / workflow / kaleo / runtime / notification / NotificationUtil.java, replace:

-    String notificationSubject = kaleoNotification.getDescription();

with the following lines:

+    String notificationSubject =
+      notificationMessageGenerator.generateMessage(
+        kaleoNotification.getKaleoClassName(),
+        kaleoNotification.getKaleoClassPK(),
+        kaleoNotification.getName(),
+        kaleoNotification.getTemplateLanguage(),
+        kaleoNotification.getDescription(), executionContext);

and then now, you can do something like this in your workflow definition:

       <notification>
         <name>request-rejected-notification</name>
+        <description><![CDATA[<#assign context = serviceContext.getAttribute("context")>${context.GRANT_TYPE} Request Rejected]]></description>
         <template>
