Workflow compose error

["Fan, Ye" <fa...@illinois.edu>]

Hi,

I followed the 10 minutes tutorial and registered echo service and application. However, when I try to compose an echo workflow (by dragging the service from the left panel to workflow panel). An error shows up: "The component is in wrong format".

I've also pasted the details below:

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Please help.
