Hi All , 
We have migrated our adf code from 11g (11.1.1.7)  to 12c (12.2.1.3) . When we run our application locally (integrated server) we dont see any issues . But when we deploy the application as shared library , UI  components are getting repeated with every page refresh or ppr activity . 
There is no change in code and the 11g application is running perfectly fine . 
Please let me know if we are missing anything here  .
Regards
