Re: problem in storing and retreiving multi lingual data

[Marcelo Emanoel B. Diniz]

on eclipse you can change the encoding of your project... try it.. you
should always use only one encoding... for everything... or else you
end up with problems like this... try to set your project encoding to
utf-8 and see if it solve your problem :)

Server communicating with Client

[Arun]

I have this situation where I want to make a RPC call when new data is
inserted into the database. I do not want to make a call to the server
every few seconds and see if there is new data. Is there anyway we can
make server hold the response until the data is changed??? Any help is
really appreciated.

problem in storing and retreiving multi lingual data

[vasem want]

Hi all,

we are developing a multi lingual application which has
oracle as the DB, the problem is that when user enters
the data it is stored and retrieved as a junk data
somehow somewhere the uni coding is being
encoded by gwt or somewhere,

we tried the same stuff through oracle forms and it is
storing the multilingual data correctly (in this case we tried chinese)

does anyone have a clue on this

cheers

Re: Can GWT complier handle annotation with enum?

[Dean S. Jones]

this works for me:

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Condition
{
Type value() default Type.OPEN;

public enum Type

}

then used:

@Condition()
public void doThing()

@Condition(Condition.Type.CLOSED)
public void doOtherThing()

Re: Questions about more than one generators apply to one class

[James]

Hi, Dean

  Thank you very much for your reply, I'm very appreciate it.

  In my situation, it's looks like following:
  

  

  

  

  Then, I have a class implements these interfaces

  public class TestGenerator implements InterfaceA, InterfaceB{
  }

  Then what happend?
  In my case, GWT only invoke one generator for class "TestGenerator",
but I expect should two?

  The generator can apply to classes as well, but I don't care if it's
only apply to interfaces. both are fine for me.

  I noticed it's fine to call a generator from generator generated
code, but this request one generator need know other generator, it's
not good enough for design, how do you think?

Regards
James

Re: Questions about more than one generators apply to one class

[Dean S. Jones]

first, Generators apply to interfaces, not classes, and yes, it's one
generator per interface... you can choose a generator based on a
property,
like the DOMImpl interfaces:




  

this may change your thinking:

interfaces can extend other interfaces. A Generator can enumerate the
inherited interfaces, and implement them as it sees fit.

also, it's perfectly fine to call a Generator from Generator generated
code, as in, you can generate the line:

private Thing m_thing = GWT.create(Thing.class);

and the secondary Generator will kick in when the m_thing is created.

fromLatLngToPixel() returns null

[G]

I am using GWT 1.5.3 with Google maps 1.0.4.

Basically, after adding map widget I am doing the following:

MercatorProjection  currProj = new MercatorProjection(16);
Point startPosXY    = currProj.fromLatLngToPixel(startPosLatLong,16);

startPosLatLong is the center of the map.

startPosXY is returning null. Can someone explain me why ?

Questions about more than one generators apply to one class

[James]

Hi, Guys,

  I got a questions, what if I have more the one generators apply to
one class, I looked inside gwt codes, looks like it's only process one
generator.

  Any idea about this?

Re: Server-only functions

Well, no, actually. The example I really want to use was the "Command"
interface above. It would mainly allow me to keep the code interface
(to be used client-side) and the code itself would be in the same
class. Then I'd have a RemoteService where you can pass a "command"
and the server component simply calls commandfromclient.execute().
Something like this :

class SomeCommand {
  private SomeType param1;
  private SomeType param2;

  private SomeType returnval;

  public SomeCommand(some parameters) {
  }

  @ServerOnly
  public void execute() {
 // actually do what's requested, using all available server
resources
 // database updates, whatever
 returnval = someReturnVal;
  }

  // suggested at google I/O
  @ServerOnly
  public void undo() {
 ...
  }
}

Note that implementing this, using 3 classes instead of 1 was actually
suggested as good practice in the google I/O session "Google App
Architecture Best Practices" ( 
http://code.google.com/events/io/sessions/GoogleWebToolkitBestPractices.html
). Why do I need to implement 3 classes in order to do this ? In
addition to needing 3 classes, they also have to be located in
radically different parts of the application, despite the obvious
relationship. Why do I need an interface PER command ? That makes no
sense in the design, why should it be forced on me at implementation ?

JDO's wouldn't be that easy to implement even with this facility since
you need to keep state (like database references, transactions, ...),
and obviously state and serialization don't go all that well together.
It'd be useful though, but would still require major surgery.

The problem I'd like to deal with in this interface is that any code
that the client calls and is executed on the server requires modifying
at the very least 3 classes (and an xml file and a static declaration
in your "main" class if you wish to give it a different path for
clarity), that have radically different functions and locations. I
understand all 3 classes, and I agree all three have to exist, it's a
good design. But they're all "plumbing" classes, having nothing to do
with the application logic. It'd be great to have a way to have client-
side logic and server-side logic in the same class, clearly separated
by using annotations.

The reverse of this feature actually exists in the gwt javascript
compiler : making sure that some methods get translated to javascript,
no matter what. This feature is embedded in the compiler and is a
class-level annotation called @ArtificialRescue where you're supposed
to pass comma-separated lists of items to "rescue" : variables,
methods and something else. It is used extensively (though it seems
not very well documented)

If I were to create a patch that followed the @ArtificialRescue
principle but with a "@ServerOnly" annotation name that was valid on a
method and submitted it, do you think it has a chance of getting
accepted ?

Kind regards,

Christophe

Re: 求助,无法在eclipse3.5中导入samples里的项目

[Sumit Chandel]

Hi all,
While the group is primarily an English language group, there is no policy
preventing anyone from posting in their native language if they have trouble
expressing or communicating their issues in English. As mentioned
previously, the machine translations can sometimes do a bad job in
translating a message (although sometimes humourous), and might not allow
the poster to correctly describe the issue they're facing. More often than
not, there are other developers in the community who speak the same language
that can reply back with some helpful information.

That said, members who post here should try their best to post in English
first and try to get their point across. If that fails, feel free to post in
your native language. If posting in multiple languages ever starts affecting
the usability of the forum for the majority of its community, we can always
consider splitting out this group into multiple groups per language.

Cheers,
-Sumit Chandel

GWT,O3d, Servlets & Database‏

[Jupiter]

Hello Everybody,
I know little about GWT & O3d.I want to develop a website which has a
3d interface.On clicking any of the objects  and changing its
properties the corresponding changes must be reflected in the
database.So what I want to know is :

1)Does GWT support O3d?
2)Is it possible to make an object in the o3d a sort of hyperlink to 2
dimensional content?
3)Is o3d and servlets connection possible?
4)Does GWT support 3 dimensional content?If so are there any sources
on the net from which I can learn from?

I would be forever obliged to anyone who can answer these
questions : )
Also if what I am trying to do is not feasible according to you please
tell me why.

Thanks and best wishes

Re: Debugging GWT App in Eclipse

[Cornelius]

Zeng, you are correct, update 16 does fix the problem. I had the same
problem and installed the latest version (JDK 1.6.0_16) and it is now
fixed. One of the bugs fixed in 1.6.0_16 is that breakpoints were not
working.

GWT 1.5 Plugin - Can I still get it?

I made the mistake of updating my GWT eclipse plugin whie prototyping

in hosted mode. Does anyone know how to get around that - or how to
get a copy of the old google plugin??

Re: How to set Font style for full application

[Alexander Cherednichenko]

Simply, style entries from the class (.gwt-label, for example) are
more important for the html renderer than element-related one.
So, what you could do is to replace style declarations from the
public.css with your own.

Also, if you're specifying fonts, be sure not to forget about fallback
ones. So, if you'd like to make a style with Times font, you should
see something similar to following:

.gwt-Label {
   font-family: Times, arial, sans-serif;
   
}

if the client's system does not have Times  font installed, it would
use arial, if no arial - any of the sans-serif fonts.

Plugin-based application built with GWT ?

[gjoseph]

Hi all,

I was wondering if anyone had pointers, ideas, examples, or anything
that could help clarify if writing a GWT-based application that would
also be based on plugins, where said plugins would consist of client-
side code (i.e gwt modules) AND server-side components... is at all
possible. These plugins can be added/updated/removed from the app,
much like osgi allows one to do with bundles.

At the moment I can't quite picture yet how to build and deploy this
sort of application (without having each plugin re-embedding the whole
of the application client code itself), especially if we're talking
dynamic (at runtime) (un/)loading of said plugins. The one way we're
sort-of considering at the moment would be to actually use the
compiler in our app (!), when plugins are added/updated/removed. That
doesn't seem like the most optimal and elegant approach ;)

I am looking into wrapper types, custom linkers, ... but it's still a
bit blurry how it all would fit together... so if anybody has any
pointer or thoughts about this subject, that would be much
appreciated !

Cheers,

-greg

Server-only functions

[Christophe]

I find the client-server distinction too coarse to work with. The
strength of gwt is at least partly in the RPC mechanism and passing
full classes.

I was therefore wondering. Isn't it possible to declare a specific
function or inner class if that's easier to only be accessible on the
server side ? I realize this poses all sorts of problems for variables
and deciding whether or not something gets serialized, but I'd be most
happy if the compiler just threw those problems in my face and
expected me to fix them.

I realize server-side there can be only one class definition. But I'd
like to "opt-out" of translating compiling specific functions, and
just get an error message if that function is used by any client code.

What I'm really looking for is something like this, and this would be
an example usage :

class getServerTimeCommand implements Command {
  Date d;

  @ServerOnly
  public void execute() {
 d = new Date();
  }

  // whoops no ServerOnly, yet calls a ServerOnly function
  public void doItAnyway() {
 execute(); // ERROR, attempting to call serverside code from
within client code
  }
}

Is it possible to do something like this ? If not, would it be
possible to implement it ? It would be extremely handy for reducing
the number of classes needed in RPC. I basically want the ability to
say about certain class members "please don't serialize this".

I realize that for certain data fields you have problems, since not
passing them to the client side requires keeping track of references,
however I think you can avoid that problem by allowing only functions
to do this. This would also enormously simplify the usage of various
java tools both server- and client-side.

Re: Announcing the Google Plugin for Eclipse 1.1.0

[Paul Robinson]

The 'Getting Started' page says you have to use Java5 if you want to use
hosted mode and you're on a mac.

I believe that if you're not developing on a mac (or if you are on a mac
and you use gwt's trunk and OOPHM) then you can use java 6.

AbstractImagePrototype v/s ImageResource - what's the direction?

[Sri]

I am experimenting with UiBinder to build the UI in a declarative
manner.

UiBinder seems to prefer the ClientBundle and ImageResource interface;
whereas all GWT documentation on the wiki indicate that we should be
using an ImageBundle with AbstractImagePrototype.

Going through GWTs sourcecode, I see that ImageResource provides
functionality similar to that of AbstractImagePrototype (combining
multiple images into 1 using the data: url scheme).

All this leaves me a bit confused - which paradigm should I be using?

thanks!

gwt 1.6 eclipse plugin

[philipmac]

Hey,

I am trying to get the gwt1.6 Sample Gilead application (http://
sourceforge.net/projects/gilead/files/) up and running.

It seems that I need to have the GWT1.6 plugin to use this, where can
I find this?


The reason I think that this is the error is because when I open the
project in eclipse, manually imported the GWT stuff via Build Path ->
Add Library, ->Add GWT stuff and App engine stuff.

Yet when I try to GWT compile it, it tells me that it is not a GWT
app.  Also in the GWT Compile popup it seems to not know where the
entry point is, even though the entry point is defined in the
Sample.gwt.xml file, as per all GWT projects.

I am hoping that if I can use the GWT for which the Gilead proj was
created, these problems will go away.

Java6 other than the .0_13 point release is fine. Remember that GWT only
emulates a subset of the JRE; Java5 vs. Java6 may not be much of an
issue for your application.

Have you looked at Ray Ryan's session at Google I/O ?
http://code.google.com/events/io/sessions/GoogleWebToolkitBestPractices.html

I believe some of the code samples (download the slides, they're much
more usable than the video ;-) ) would answer your questions.

Could you explain what you mean by "type name"? Also, which kind of
events would you like to create? I need some more context to
understand the question...

> - public HandlerManager(java.lang.Object source) you supply an object
> to the constructor, isn't it just one bus /    application ?

HandlerManager is what manages the events within widgets too. For, for
instance, someClickEvent.getSource() to be the Button widget you just
clicked, the HandlerManager backing the Button's event handling needs
a reference to the button instance.
...but there are many cases where you don't need a source (such as
when using HandlerManager as an event bus), in those cases, just use
'null'.
(note: History also uses a HandlerManager, and it uses a 'null'
source, so ValueChangeEvent#getSource() in your
ValueChangeHandler will return null)

> - Can I use event bubbling?

Er, at which level? bubbling from which point to which point? If you
mean "in a custom widget, can I register a clickhandler to be notified
whenever a child DOM element is clicked?" then yes, because click
events bubble on the DOM:

Re: Announcing the Google Plugin for Eclipse 1.1.0

I was under the impression that GWT would not work with Java6, anyway. 
Did I misinterpret something?  We actually backed ourselves to Java5 for
compliance.

There's a bug in JDK 1.6.0_14 which causes breakpoints not to work.
Check which JDK version you have. 1.6.0_16 is out and allegedly fixes
this bug.

Re: How to set Font style for full application

[jhulford]

Otherwise, if you only really want to change the font and not bother
w/ copying the GWT css, just use the "!important" CSS declaration in
your host page:

body {
font-family: "Times-New Roman" !important;
}

In the interest of being overly pedantic, Times is a proprietary font
generally only found on Windows machines so your page is going to look/
render differently on other OS's.

Problem deploying with Firefox/Chrome

[Rahul]

Hi,
There are few posts with problems with firefox but i was not able to
find a solution reading those so i am having a new post.
My code runs fine on IE but it fails on Firefox/Chrome.
I am using RequestBuilder to parse some xml files and showing them as
labels on my UI.

The UI is build perfectly wit IE but not with Firefox/Chrome
I am believing that it gets an null response received with
RequestBuilder with firefox/chrome.
any idea whats causing this problem and how to solve it

Re: Announcing the Google Plugin for Eclipse 1.1.0

[Shavkat S]

Hi everyone!
I've installed
eclipse-jee-galileo-win32.zip
gwt-windows-1.7.0.zip

and I am going through the "Getting started" tutorial for GWT (http://
code.google.com/webtoolkit/tutorials/1.6/debug.html)
Everything works just fine until I get the Step 6: Debugging a GWT
Application.

Execution of the GWT application doesn't stop at the breakpoints that
I set in Eclipse.
At the same time it works non-GWT applications.

I am new to GWT and Eclipse so I can miss something.
Do I need to do something specific for GWT application to debug it in
Eclipse?

Thanks!

Re: How can I get Image from ImageBundle by String?

[Dean S. Jones]

Actually, I decided to write a Generator for this, being curious

You would have an ImageBundle

public interface IconsImageBundle extends ImageBundle
{
  @Resource("save.gif")
  public AbstractImagePrototype saveIcon();
}

Second you would have an ImageBundleMap

public interface IconsImageBundleMap extends ImageBundleMap,
IconsImageBundle
{
}

IconsImageBundle icons = GWT.create(IconsImageBundle.class);

Then is can be used BOTH ways:

AbstractImagePrototype save = icons.getByName("saveIcon"); // this CAN
return NULL.

or

AbstractImagePrototype save = icons.saveIcon();

also you can get the collection underneath:

Map list = icons.getImageMap();

Also, you can implement MULTIPLE ImageBundles and it coalesces them:

public interface ApplicationImageBundleMap extends ImageBundleMap,
IconsImageBundle, LogosImageBundle, ActionsImageBundle
{
}

If anyone is interested, drop me a line.

GWT HandleManager model

[WardLoockx]

Hello,

I'm very new to GWT and having some questions about the event system.

What I wan't to do is fire events when my async calls are executed so
I can listen to this events to update the UI.

my questions:

- Can I create event on the fly ? with just a type name (so I can
listen on that type of event)
- public HandlerManager(java.lang.Object source) you supply an object
to the constructor, isn't it just one bus /application ?
- Can I use event bubbling?

Do you guys now some answers or good docs ?

Thx,
Ward

Re: How to set Font style for full application

[Brian Dorry]

Parves, I had a similar issue to yours. What I did was copy the
stylesheet for the theme I was using, removed the theme declaration
from the entry point, and referenced the copied stylesheet manually.
This let me make the GWT styles load before my own set of styles.

sockets and google gears not work?

[jfcog...@gsyc.es]

Hi,

I have an app that use Gears in the code, and we use jsonp to access a
socket in the localhost:8000 to take the json information in the
server.
If we take down the Gears , the app access the socket perfectly, but
when we use the Gears aplication the sockets going down... maybe gears
and java sockets not work together?

please I need your opinion :)

thanks for all.

It's an English language group, so 'yes'. If it were a free-for-all as far
as languages were concerned then it would become much less usable for
everyone.

Some people in the past have written in their own language with a machine
translation underneath. Answers have been given by English-speakers in
English, also with a machine translation back to the OP's language. That
seems to keep everyone happy and works quite well.

There's a story that 'To be, or not to be. That is the question.' was
translated into Japanese and then back to English and ended up as 'It is, it
isn't. Isn't it?' It's not a perfect science yet.

calling java function from an eval

[samsus]

Hello Everyone

Im trying to call a Java function from an eval, so far no luck, any
ideas on how this could be done?

this is the code:

public native void runj()  /*-{
  $wnd.eval("new MyAjaxClass($('#myDiv'),{onSubmit : function
(file, ext){th...@com.site.myclass::myOnSubmit(Ljava/lang/String;)
('test');}});");
}-*/;

public void myOnSubmit(String string) {
Window.alert("its submiting");
}

i have also tryed

public native void runj()  /*-{
  $wnd.my_call = function(id) {

th...@com.site.myclass:myOnSubmit(Ljava/lang/String;)(id);
}
  $wnd.eval("new MyAjaxClass($('#myDiv'),{onSubmit : function
(file, ext){my_call('test')}});");
}-*/;

any ideas?

it has to be inside eval, otherwise it wouldnt work

Re: SmartGWT (or any other GWT-compatible JAR) integration

[CI-CUBE]

no one who can help? It's just crazy :-( SmartGWT jar's are registered
in the Classpath - no matter if in the Bootstrap or User Entries,
there are also in the Source Path - under Default.

Once again, if I copy the whole project directory and install it at
home, in an identical setup (Eclipse, GWT, App Engine, SmartGWT, JRE
versions) this works perfectly w/o any mod.

What further settings could be relevant that are outside this project
directory (Workspace settings, Registry)? I'm starting to spend too
much time on this minor issue :-(

TIA,

   Ekki

"Unknown runtime error" on IE (all versions)

[David Given]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

My app is erroring out obscurely on all versions of IE, but it works
fine on FF and Chrome.

The error I'm getting is:

Message: Unknown runtime error
Line: 12512
Char: 3

The actual Javascript code --- compiled with Pretty --- is in my init
function and is an entirely unobjectionable:

function init(){
  !!$stats && $stats({moduleName:$moduleName, subSystem:'startup',
evtGroup:'moduleStartup', millis:(new Date()).getTime(),
type:'onModuleLoadStart', className:
'com.cowlark.stellation2.client.Stellation2'});
  $clinit_6();

// * this line is causing the error *
  $doc.getElementById('loadingMessage').innerHTML = '';

  $show($LoginDialog(new LoginDialog()));
}

This is generated from the equally unobjectionable Java code:

public void onModuleLoad()
{
  DOM.setInnerHTML(DOM.getElementById("loadingMessage"), "");
  authenticationFailure();
}

Any ideas as to what might be going on here?

...don't try to update the label on each key; prefer using a timer
instead (the timer could be reset on each key, to update the label
only a few milliseconds after the last key press event; or just run at
fixed intervals).

See http://www.quirksmode.org/blog/archives/2009/08/when_to_read_ou.html
(at the end, the comparison between computation time and rendering
time)

It all depends which widgets you use for the layout; FlowPanel for

Several solutions:
 - don't build your form with GWT and instead wrap GWT widgets around
existing HTML elements:
  TextBox myBox = TextBox.wrap(Document.get().getElementById("my-
box"));
   i.e. use progressive enhancement as you were used to with jQuery.
And if you want a jQuery-like approach to get elements, have a look a
GQuery: http://code.google.com/p/gwtquery/
   (beware: you cannot wrap nested elements; well, actually, you can,
at your own risks; either disable assertions in hosted mode and/or see
issue 3528)
 - use an HTMLPanel with placeholders where you'll inject your GWT
widgets (there's no HTMLPanel.wrap() but it could be somehow
simulated:
  RootPanel rootPanel = RootPanel.get("thingToWrap");
  HTMLPanel panel = new HTMLPanel(rootPanel.getElement
().getInnerHTML());
  rootPanel.getElement().setInnerHTML(null);
  rootPanel.add(panel);
   it'll add a  –or whatever "ag" you passed as the second
argument to HTMLPanel's ctor– in between the "root panel" element and
its children as they appeared originally in the HTML code)
 - use UiBinder that'll ship in the upcoming GWT 2.0

I'd personally favor UiBinder if possible.

Re: Firefox and Chrome Autocomplete Login Forms

[George Georgovassilis]

Ok, how about this:

A user works, anonymously ( = not logged in ) with your application.
At some point he decides (or the application decides) that he wants to
log in. You navigate him to the (non GWT) login page, he does the
login and you reload the application.

You can tell your application that the user is logged in either by
putting that information into a hidden  in the module page which
your app can query then. Or your app can simply test for the existence
of a cookie (i.e. jsessionid).

Re: Firefox and Chrome Autocomplete Login Forms

[spike2...@googlemail.com]

Sadly not an option
Login is optionally in my app, you can, but you don't have to.
If I use an IFrame, I can't access the Information generated in there.
I could have used the User-Capability of Google App, but I did't
exactly for that reason.
I hate these Worarounds.

Re: Firefox and Chrome Autocomplete Login Forms

[George Georgovassilis]

Hi Spike,

I was pondering the exact same thing the other day. From all the
experiments I made, only FF was able to somewhat reliably remember
passwords. My understanding is that you need a structure with a form,
a login textfield, a password textfield and a submit button:







There _has_ to be a form that submits to the server, otherwise
browsers won't recognise this as a login form. To make things worse,
the login form has to be there in HTML in the page loaded from the
beginning. My attempts to create it in runtime via DOM manipulation
made it invisible to the password completion mechanism.

I'd advise you to use a completely decoupled login form and load your
application only after the login page.

Re: BlackBerry Compatible

[Jan Ehrhardt]

RIM is developing it's own browser engine, while iPhone and Android use
Webkit. I'm not sure if the Blackberry browser is able to run most
JavaScript  apps. I think, you should try, what happens, but I'm sure it's
not supported.

MVC in forms in gwt? gwt forms best pratices?

[samsus]

Hi Everyone,

This past week i have been working on a project where the project is
in php, it has diferent php pages, and im using gwt as a javascript/
jquery substitute, specially for forms.

The problem im getting with gwt-created forms is that, the designer
doesnt seem to have control over it.

With normal html + jquery there would be a html form, the design could
style it anyway he wanted, and put it inside tables, or some neat css
divs and fieldsets, and i would simply apply jquery over it for the
widgets i need (e.g autocomplete) or validations.
In GWT however, the entire form is generated by Java, and in resulting
code the fields of the form are inside messy tables. further, if the
designer wants to change , say, something as simple as the order of
two text boxes, he has to edit the java code, which is not a good
pratice.

Anybody knows a "smarter" way to do this?

onChange, onLostFocus events not receiving in Firefox

[y2ken]

My GWT1.5 app has few onChange and FocusListener attached to the
TextBox, and everything is working
fine in IE and debug hosted mode in Windows.

However, once i start testing the deployed app in  Firefox(on Windows
Vista), onChange and onLostFocus event is not receiving from the
listener. Strange thing is, i can make it work in Firefox if i
minimize the browser and restore it and then the listener is receiving
onChange and onLostFocus event.

Another way to make it work (manually) is to turn on Firebug and
inspect one of the element, and then after that my listeners will
receive the corresponding events correctly.

Anyone have seen such behaviour before? is there any workaround or
fix?

Firefox and Chrome Autocomplete Login Forms

[spike2...@googlemail.com]

Hi
I'm building an App, which dynamicall builds a Widget where you can
log in. I'm using 2 TextBoxes, a login-username and a password-box in
a FormPanel in a PopupPanel.
On the onSubmit-Event I make an AJAX-Request to log the user in.
I didn't succeed in triggering the Autofill-Ability of Chrome or
Firefox. Does anyone know what preconditions have to be set to trigger
this.
I gave the textboxes a name and an id, but it still doesn't work...
Does the Autofill-Ability only work on HTML-Pages?

Any Ideas?
