Asynchronous Views not working from Portal

Hello Experts,

I have developed application to handle Asynchronous views.

That application is working fine if we run standalone without integrating into portal.

I am trying integrate application portal, but that is not working

Enabling the Portal to Process Asynchronous Web Dynpro Views - Developing Java Web Dynpro Applications - SAP Library

Getting below exception while doing preview

java.lang.UnsupportedOperationException: Recursive Embedding is not supported.

Please help me with this issue.

Satya.
