Unwrap exception in ErrorPageWriter.handleThrowable
---------------------------------------------------
Key: MYFACES-3193
URL: https://issues.apache.org/jira/browse/MYFACES-3193
Project: MyFaces Core
Issue Type: Sub-task
Affects Versions: 2.1.2-SNAPSHOT
Reporter: Martin Kočí
Priority: Trivial
If user sees this exception:
javax.faces.FacesException: java.lang.NullPointerException
at
org.apache.myfaces.shared_impl.context.ExceptionHandlerImpl.wrap(ExceptionHandlerImpl.java:241)
at
org.apache.myfaces.shared_impl.context.ExceptionHandlerImpl.handle(ExceptionHandlerImpl.java:156)
he/she thinks sometimes that this is a NPE (or other exception) from myfaces
codebase. But callstack continues:
Caused by: java.lang.NullPointerException
at cz.kocicak.myfaces.ManagedBean.getValue(ManagedBean.java:2
but nobody reads it all.
To prevent this misunderstanding, unwrap exception in ErrorPageWriter.
