I have just migrated to Tomcat 8. I used to work with system property org.apache.el.parser.COERCE_TO_ZERO=false
so empty strings, numbers, booleans etc. are treated as null
.
In Tomcat 8, EL 3.0, it is supposed to be the default but it is in fact converting null
string to empty string ""
on JSF side.
It is supposed to be a bug and it is supposed to be corrected but I'm not able to get it working in TomEE snapshot (Tomcat 8.0.27.0, MyFaces 2.2.8).
