Re: FMT tag and form bean

[Vic Cekvenich]

I would like to format in the JSP if possible (for both).

Let me just restate what I think you are saying:
"Since JSTL can format strings, allways format and localize in the formBean".

So as you point out, I can format and localize both in the bean. (Ex: formBean.setLocale(x) )
So probably a better choice.

But... since I like how the FMT tag works.... not sure what "best" approach is. I almost want to cross post to JSPTag-user, see if Geary is around. but it's really not that big a deal.
A student in a class asked why this was and I was stuttering, so I posted to get it of my chest and maybe as a wish list for HTML-EL tag.

You and Ted pointed out some things however.

Thanks as always Ted and Martin.
I would still have to format the number in the bean for Form, and
localize dates (for the Candian dates), etc in the bean class.  If the
page is read only, I would format in JSP.

I guess I don't understand. Why do you need to do formatting in the bean,
and why is it different if the page is read-only? You should be able to use
JSTL to do this in either case.

So far getAge() and
getAgeInt() look ok. I wonder which way the faces tag will work.
(yes, if know, if I copied data for the form bean .... but if I have
nested and multi row and many to many, it's kind of a pain; one day I
will write reflection with dynaRowSet to clone nesting, localize, format
and put in basicPortal)

I have been nudging people toiwards JSTL.
A nice feature is FMT tag that formats the number, date, etc. in the
JSP. FMT tag needs the formBeans to return int!

No, it does not. If you provide a string to the format tags, such as
<fmt:formatNumber>, it will convert it to the appropriate numeric type.

Try

the following:

----- cut here -----
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"; %>

<%
   request.setAttribute("foo", "1234567890");
%>

<fmt:formatNumber value="${foo}" type="currency"/>
----- cut here -----

To avoid any question of what other JSTL tags might be doing, I've
explicitly stored a string in a request attribute. The output from the

above

page is:

$1,234,567,890.00

The <fmt:formatNumber> tag did its job just fine when passed a string
instead of an integer.

So if one does a FORM for updates you create formbean with String
getAge(), and number formated in Java before returning the String.

If then you just want to display the # (no update) you need to create a
bean with int getAge(), and FMT it in JSP.


So return int for JSTL and String for formBean.

A prefered solution is that HTML tag is able to do formating like FMT

tag.

Also, it be nice if tiles was able to do some EL, or have a nicer way of
FORWARDING to diferent JSP from the tile action one day.
