CE Update Event: any way to pass before/after property values to a workflow?

Question

I've configured a FileNet workflow subscription on Add, Update and Delete events. The workflow calls a Java component to send a notification message (to a third party).

We would like to see "before" and "after" property values in the notification message for "Update" events.

The "Event" object that triggers the subscription has a "Modified Properties" member, so I was hoping I could just create a corresponding "ModifiedProperties" string array in the workflow, and have the subscription map "Update.ModifiedProperties = ModifiedProperties". Unfortunately, the Event's "ModifiedProperties" only gives the NEW value, not the "before" value. <= So I don't see any way to get "before/after" values directly from the subscription...

It looks like the "UpdateEvent" object also has an "OriginalObject" member ... and I might be able to use the Java API to get the "before" value from the OriginalObject.

Q: Does this sound plausible method for getting the before/after document property values?

Q: Any ideas how to pass the "OriginalObject" object from the subscription to the workflow, so the Java component can use it?

The target platform is P8 5.2.1; I'm developing on P8 5.5.

if(objEvent instanceof UpdateEvent) { try { String strModifiedProperties = ""; UpdateEvent updateEvent = (UpdateEvent) objEvent; StringList propertyNames = updateEvent.get_ModifiedProperties(); Iterator iterModifiedProps = propertyNames.iterator(); while(iterModifiedProps.hasNext()) { String modifiedProperty = (String) iterModifiedProps.next(); strModifiedProperties = strModifiedProperties+modifiedProperty+","; } strModifiedProperties = strModifiedProperties.substring(0, strModifiedProperties.lastIndexOf(",")); } catch (Exception e) { System.out.println("onEvent : Exception while executing UpdateEvent: "+e.getMessage()); } }
