Capture form Data while catching Task Create events -

Hi,

I want to create any asynchronous event to trigger when a new task is created in particular process. I did the event filters and able to capture the task Id and process Id for that created task. However, I could not find a way to get the xml data associated with the task.

(My Assigntask contains form template and input xml )

I see that in 8.2, there was a service called 'AddAttachmentsToTask' and operation called 'getFormAssociatedWithTask'  to capture the related data using task Id. I'm not seeing that in ES 2.5.

Your help is highly appreciated.

Thanks,

krishna
