We have a workflow that is made a business process and is invoked by another workflow.  

On workflow designer we can see the step of business process (when search and click on business process tab).  

The workflow shows that the business process did get invoked and waiting for user input at "Waiting for Entry" activity.  

But the Business Process pane of the document in client shows "No business processes have been run on this entry".

This business process is available and can be started manually in the client.  But for some reason it did not show up on client when invoked by other workflow.  Anyone know how to fix this?  Thanks.
