FMT tag and form bean
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!
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.
.V
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.

Re: FMT tag and form bean
Posted by Ted Husted <hu...@apache.org>.
The ActionForm doesn't actually care about the property types. It's just
that we can't roundtrip whatever they happen to type into an int field
if validation fails.
The JavaBean spec doesn't allow you to overload properties. Though, you
could have getAge and getAgeInt, which refered to the same String field.
I don't know what the FMT tag does under the covers, but I think the MVC
solution would be a bean with FMT features that could be exposed as a
JSP tag or whatever. Or, better yet, a DynaBean that allowed FMT
settings for each field.
If such a bean was used to back a html tag, then whatever the bean
returned is what the html tag would display.
The issue would be what happens when the input doesn't format correctly?
Does the tag change the input or display input that doesn't meet the
specification. If they input "a57k" for an int, what do they get back?
There lies the conundrum =:0)
I suppose one solution would be to pass the bad input off to the
validation message somehow. So you could display a blank field (or 57)
with a message like "You entered a57k but a whole number was expected".
But, in any event, I think the key is to think in terms of the
data-carrier rather than an implementation detail, like the tag.

OK, now I see what you're saying. I was also assuming <html:text> had a
feature it turns out not to have
(yet ;). Still, you could do it like this, although it's a bit ugly:
<fmt:formatDate var="temp" value="${yourFormBean.startDate}" ... />
<html-el:text value="${temp}" ... />

Re: FMT tag and form bean
Posted by Vic Cekvenich <vc...@basebeans.com>.
Let's try again:
:-)
http://jakarta.apache.org/struts/userGuide/struts-html.html#text
This does not let me localize or format.
Lets say I have a bean that has a #, String getStartDate().
If I sometimes use this bean on a read only page, I could do JSP FMT to
format and localize.
I sometime want to use the same bean on a R/W form submit page.
String getStartDate(), hut html:text does not format or localize. The
traditional approach I used was to format to native types inside the
setters/getters.
Point is I can't format a localize in html:text, but can in JSTL.
So the only place is in the bean, inside the getStartDate() {}.
The other alternative is to copy.
And I must have misunderstood what you were saying, but I think I now
understand the issues surouding it enough.

No, that doesn't make any sense. I'm saying "Since JSTL can format strings,
always format and localise in the JSP page". I don't understand why you need
to do any of it in the bean, hence my last message.

Re: FMT tag and form bean
Posted by Vic Cekvenich <vc...@basebeans.com>.
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.

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.

Re: FMT tag and form bean
Posted by Vic Cekvenich <vc...@basebeans.com>.
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. 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)

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.
