Coercion + EL + Facelets

[Walter Mourão <wa...@gmail.com>]

Hi folks,
I'm patching some applications regarding the "change" in the coercion rules
of EL (null goes to zero if the destination is an Integer) and I have some
questions to discuss.

1 - Does it really changed in JSF 1.2 or Tomcat had a wrong behavior ?
2 - Do you think (or know) the specification will change or I really have to
adapt my to application to support such a kind of situation ? This question
is very important to me because if I think it is a temporary behavior, I
will use the *org.apache.el.parser.COERCE_TO_ZERO* tomcat property,
otherwise I will adapt a lot of projects...
3 - doesn't it really sucks ?

( If you don't know what I am talking about, take a look at
http://www.irian.at/blog/;jsessionid=8401E3770357871EAE2E38799810B7FB and
https://issues.apache.org/bugzilla/show_bug.cgi?id=48813 )

Thanks,

Hi,

1) Yes, it really changed from JSF 1.1 to 1.2, because of the
introduction of the unified EL.
2) Nope, but you can use a custom EL impl which lets you customize the
coercion rules, like e.g. juel [1] and its TypeConverter
3) Agreed!

Regards,
Jakob
