Use of liferay notification portlet with Activiti BPM

[montej]

I am using activiti BPM in liferay for workflow.
I am currently created some task in activiti diagram.
when in workflow user create content then i want to give him notification.
I create activiti diagram so user get email notification.But i also want to give me notification him with liferay notification portlet.
How can i do that?
Is there any properties to cinfigure in Acitviti task or write some script?
Any help will be appriciated.

Hi Montej,
So you would like to receive the notifications inside the Notifications portlet.
In this case I think you should use a ScriptTask with a groovy script or a ServiceTask with a java delegate class.
anyway.. you choose what you prefer (I would go with a service task)
this custom "action" should create a new UserNotificationEvent with a call like:
<java>
UserNotificationEventLocalServiceUtil. addUserNotificationEvent(userId, notificationEvent);
</java>
which will be read later by the Notifications portlet.

I didn't implement a test for this approach but i just had a look over the portlet sources and I think will work.

Thanks for your reply, I will try with this trick.
But can i get built in  notificationEvent object or i have to create it in script?
I know that userId i can get directly but not sure about notificationEvent.

Hi,
the notificationEvent is a new object you should create it here inside your script/delegate class.

since the NotificationEvent class is loaded in the portal classLoader, you are able to create a new object in any of the portlets. (as you know the portlet class loader is a child of the portal classloader)

Hi ,
i am getting userId by <activiti:expression>#{userId}</activiti:expression>
I want to get "workflowInstanceId" and "workflowTaskId" id for setting up jsonObject for creating NotificationEvent.
So is there way to get this variable ?

I have got solution for notification send when task assgin to user.
Only enable email notification by following code ,the notification in notification portlet display by it self.  
<serviceTask id="servicetask1" name="Send Mail" activiti:type="mail">
      <extensionElements>
        <activiti:field name="to">
          <activiti:expression>#{liferayService.getUserEmail(userId)}</activiti:expression>
        </activiti:field>
        <activiti:field name="subject">
          <activiti:expression>Review Task</activiti:expression>
        </activiti:field>
        <activiti:field name="html">
          <activiti:expression>Review the below task</activiti:expression>
        </activiti:field>
      </extensionElements>
    </serviceTask>
