If you are facing an error of JS like and you are handling enter key using AdfKeyStroke.ENTER_KEY
Message: ‘undefined’ is null or not an object
Don’t be afraid, its not your fault. It is happening in jdeveloper 18.104.22.168 .
Cause- Might be when we use AdfKeyStroke.ENTER_KEY, it generates some internal JS event by framework, which can cause this issue.
In all other version , it is working fine.So if you upgrade your application to Jdeveloper 22.214.171.124
and you got this error, Raise an SR to Oracle.There is already bug raise by Oracle . Bug # 19137193
