[Core] Missing f:event tag (Declarative Event Handling) in JSF2??
Hi,
I saw on several places the mentioning of a "Declarative Event Handling" in
JSF 2. But I couldn't find support for the <f:event> in Myfaces 2 beta. A
quick look into Mojarra revealed that they also don't support the tag.
Looking up the tag documentation shows a difference between the 2 sources .
The VDL Tag Library Documentation for JSF (**
https://javaserverfaces.dev.java.net/nonav/docs/2.0/pdldocs/facelets/index.html)
doesn't have a mention of <f:event> but the VDL tag Library Documentation
for facelets2 (
https://javaserverfaces.dev.java.net/nonav/docs/2.0/pdldocs/jsp/index.html)
has the tag listed.
Is there a Declarative Event Handling in JSF 2 (and thus missing code) or
not ??
Thx
regards
Rudy.

Hi Rudy,
If you think this is a specification bug, then please file an issue for that
on https://javaserverfaces-spec-public.dev.java.net/. And very great would
also be if you would create a myfaces issue afterwards with the link to the
spec-issue.
Thanks!
Regards,
Jakob

Hi,
Sorry, I was a bit too fast saying <f:event> isn't implemented, my fault.
But I was trying to use the tag on a form, and there wasn't no call to the
listener.
After diging into the code, I found out that Myfaces implemented the
PostValidateEvent and PreValidateEvent only on EditableValueHolders
(specified in the spec) and not for instance on the form (as Mojarra does,
probably because the specs aren't saying that the ValidateEvents are not
restricted to EditableValueHolders)
But now I have problems creating a custom tag based on java class tagged
with @FacesComponent (trying to extends HtmlForm so that I can mimic Mojarra
behaviour. Just only for demonstrative purposes for ExtVal functionality
which is much easier and portable). But that is another story.
regards
Rudy.

Actually the spec clearly states that all new features tagwise will be
Facelets only since JSP is only seen as legacy technology.
But that does not prevent anyone
backporting those features if he/she is willing to do that :-)

Hi,
The tag exists (and works) only if you're using facelets-2. It is no
supported on JSP (like some other new features like e.g. f:ajax).
