This issue is resolved now. Problem was missing Unauthenucated access configuration. /isc/pki weba pplication should have unauthenticated access enabled to get the certificate information to diaply in the tab above.

May be you could try simply passing message to the required namespace:

• Create two operations in the current namespace
• Configure one of the operation as TCP connection to a business service in the second namespace where you have the required operation(see sample config) 

• Configure the business service in the second namespace as pass-through to the required operation in that namespace
