Subject javax.faces.INTERPRET_STRING_AS_NULL does not work with EL 3.0
Date Fri, 10 Jun 2016 13:50:31 GMT
The EL 3.0 has some changes in it that break
javax.faces.INTERPRET_STRING_AS_NULL. This is detailed here [0] under the
section 'EL 3.0 (2013-current)'. To get around the issue, the page
introduces the class EmptyToNullStringELResolver that needs to be installed
in the application.

Should the documentation for the JSF 2.2 web context parameter
javax.faces.INTERPRET_STRING_AS_NULL [1] be updated since it no longer
works with EL 3.0 out-of-the-box?
