Hi, I am migrating from myfaces 1.2 to 2.2.7 version and richfaces from 3x to 4x version.
I am receiving a warning followed by a NPE as below Jun 05, 2015 11:42:43 PM org.apache.myfaces.renderkit.RenderKitFactoryImpl getRenderKit WARNING: Unknown RenderKit 'HTML_BASIC'. Jun 05, 2015 11:42:46 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/MSJ] threw exception [null] with root cause java.lang.NullPointerException at org.apache.myfaces.lifecycle.DefaultRestoreViewSupport.isPostback(DefaultRestoreViewSupport.java:143) I have followed the migration steps and debugged the source code as well but not able to reach to the root cause of the issue. Can you please help me in understanding where I am going wrong? Thank you!!
