Raminderjeet Singh commented on AIRAVATA-401:
---------------------------------------------
This is really good thing to do. it may be a good idea to change the schema so
that user can mark input parameters as optional. Just allowing empty or null
parameters can create problems like clients setting null value but user
consider its a mandatory filed for the application. similar requirement applies
to outputs also.
