Tapestry 5.0.15 DateField localization problem
In new corelib\components\DateField one can find:
JSONObject onParse()
{
...
response.put(RESULT, date.toString());
...
}
For my timezone it returns: "Mon Sep 01 00:00:00 EEST 2008", but then in
datefield.js it tries:
var resultHandler = function(result)
{
var date = new Date(result);
date would have Invalid Date value, and the whole calendar popup would show
up ruined.
I tried messing with FireBug in console and it looks like EEST timezone name
is a problem, if I put GMT+3 in it then javascript engine in my FF would
parse that date.
Possible fix would be changing date.toString() to date.getGMTString() -
which is deprecated long time ago.

Looks as a right fix, in my first post I pointed to the root of this problem,
but I'm too lazy to build Tapestry from sources just for this simple fix.

I think it should work, but I'm not absolutly sure. Since you can't
select the time zone in the calendar (hopefully!), you may be right to
avoid transfering timezone information, because it could change the day
when going from/to the server to/from the client.
Example.
I'm at GMT+11. If write the following javascript:
var d = new Date("Mon Oct 20 00:00:00 GMT+1200 2008");
document.write("<p>"+d+"</p>");
It gives me:
Sun Oct 19 2008 23:00:00 GMT+1100 (NCT)
While for this javascript:
var d = new Date("Mon Oct 20 00:00:00 2008");
document.write("<p>"+d+"</p>");
I get:
Mon Oct 20 2008 00:00:00 GMT+1100 (NCT)
Given the semantics of the calendar (I write "10/20/2008", I want to see
"10/20/2008" on the server side), I think its better to avoid timezone
information.

The fix I implemented was to use a simple number (milliseconds since
the epoch) as the transfer format. I'm concerned there may be a time
zone issue though, when the browser time zone is not the same as the
server time zone.

Well I still had stability problems under IE (surprise!) so I tried to
fix the thing in Tapestry itself. AFAIK, it work flowlessly.

Well... for this to work cleanly, you also need to add an "if" around
the whole datefield-tzfix.js, otherwise you get an error when no
datefields exist on your page:
-----snip----------snip----------snip----------snip-----
if (Tapestry.DateField != null) {
[...previous file contents...]
}

Hello people,
Thanks for your fix Konstantin !
For those (like me) who are using a layout/border, I've refactored your
code in a mixin that includes the workaround javascript in a mixin
suitable for inclusion in layouts. This is a global fix that works for
datefields in beanforms.
Here's my mixin code:
-----snip----------snip----------snip----------snip-----
public class DateFieldTzFix {
// XXX ---- workaround for TAP5-225 (affects v5.0.15) ---
@Inject
private RenderSupport renderSupport;
@Inject
@Path("datefield-tzfix.js")
private Asset script;
@AfterRender
void afterRender(MarkupWriter writer) {
renderSupport.addScriptLink(script);
}
}
-----snip----------snip----------snip----------snip-----
To use the mixin, simply put this in your layout component:
-----snip----------snip----------snip----------snip-----
public class Layout {
[...]
@SuppressWarnings("unused")
@Mixin
private DateFieldTzFix dateFieldTzFix;
[...]
}
-----snip----------snip----------snip----------snip-----
I also advice people (like me, again...) in uncommon locales to add
their GMT specifications in the resultHandler function. My contribution
is :
tzfix = tzfix.replace(/NCT/, 'GMT+1100');

Weird T5 error page versus component templates
Posted by su...@gmx.de.
When I put the following code into a page template it works, if I put it inside of a component template embedded within a page, it comes up with the error:
"The prefix "t" for attribute "t:type" is not bound."
The code:
<div t:type="t5components/SlidingPanel"
subject="literal:panel subject"
style="width: 350px;" closed="false">
<div>
blablablabla
</div>
</div>
Any ideas?
Thanks!
Toby

Thank you for your fix, It can work by default. but When i user

'2008/00/26' too .the month is always "00".

Ok. I've created a workaround.
package myapphere.mixins;
import org.apache.tapestry5.annotations.IncludeJavaScriptLibrary;
import org.apache.tapestry5.annotations.MixinAfter;
@IncludeJavaScriptLibrary("datefield-tzfix.js")
@MixinAfter
public class DateFieldTzFix {
}
-----
Using in:
-page class:
private Date dateValue;
@Component(parameters = {"value=dateValue"})
@Mixins("DateFieldTzFix")
private DateField dateField;
-tml:
<t:datefield t:id="dateField"/>
And I added just my timezones: EEST, EET. So you'll have to add your own too
in datefield-tzfix.js script see attachement.

I encounter the same problem.
I use:
<span t:type= "Label" t:for="userDateField"></span><input t:type
="DateField" t:format="yyyy/mm/dd" t:value="userDateField"
t:id="userDateField"/>
In FF explorer I choose today It return "2008/00/13".
In IE explorer I run into javascrip error 'style' is null or not an
object. and when I second choose date It return "2008/00/13". too
