Re: History does not work in IE
Hi
Ensure the history iframe is on your GWT host page as in:
iframe src=javascript:'' id=__gwt_historyFrame
style=width:0px;height:0px;border:0px/iframe
It appears the IE implementation still depends on it while other
browsers can work without it. Maybe the GWT Team can say something about
that!
Had similar problem earlier this month and that worked for me.
Cheers.

I try to use the GWT history with a value change handler, what is

in the onModuleLoad method looks like this:
HorizontalPanel basePanel = new HorizontalPanel();
RootPanel.get().add( basePanel );
History.addValueChangeHandler( new ValueChangeHandlerString() {
public void onValueChange(ValueChangeEventString event) {

History.addValueChangeHandler(...)
After compiling with DETAILED style, I got:

Container managed security and time-out of the webapp.
In my GWT application MyApp I'm using container managed security
(logon through html form with
action=j_security_check and input elements j_username and j_password).
Works fine except
when the application times out: the container doesn't allow the RPC
service to be executed anymore on the server, so it throws back the
html of the logon-form. But the client side RPC code has no 'solid'
way of detecting this.
Currently I've implemented it as follows: in the onFailure method,
check if it's an InvocationException, then check if it contains a bit
of html that's in the logon-page.
If yes, then redirect to the start page of my app.
AsyncCallbackVoid callback = new AsyncCallbackVoid()
{
public void onFailure(Throwable caught)
{
if ( (caught instanceof InvocationException)
(caught.getMessage().contains(htmlheadtitleMyApp
Logon/title/head) ))
{
Window.Location.assign(MyApp.html);
}
else
{
..
Is there a more proper way of doing this?
Regards,
Willem

Re: Container managed security and time-out of the webapp.
Hello
There have been many approaches to securing GWT applications, I think
it all depends on your application workflow. But an approach similar to
yours that i'm used to follows:
- Create a servlet filter to filter requests for the GWT module
servlets. Then in the doFilter() method do something like ...
HttSession session = request.getSession(false); // get the
session attached to request
if(session == null) { // the case if client is not logged in
ression.sendError(HttpServletResponse.SC_UNAUTHORIZED);
} else {
chain.doFilter(request, response); // pass request on to
the GWT servlets
}
- Next create a custom AsyncCallback handler for the client side
wherein the onFailure() method does something like this ..
void doFailure(Throwable t) {
try {
throw t;
} catch (IncompatibleRemoteServiceException e) {
// this client code is not compatible with the server
refresh the browser to download new one
Window.Location.reload();
} catch (StatusCodeException e) {
// the call didn't complete cleanly
switch (e.getStatusCode()) {
case 401: // Authentication required; reload the whole
page so server can enforce login
Window.Location.reload();
break;
default:
// do other tests or pass on to an abstract method
so you can do more localized processing
}
} catch (Throwable e) {
// shouldn't get here though ...
}
}
then you can use the custom AsyncCallback handler in other RPC requests
of the application
However, this approach appears to require some application design issues
- the URL (especially the history tokens) you choose SHOULD be mapped
to known application states, so that the application can appear to
return to where it was before the Window.Location.reload() call.
- the host page of the GWT module SHOULD be placed behind a security
constraint
This way i've been able to use container managed security and standard
servlet security annotations in my application
Just another way of achieving the same result :-)

Borders not showing on FF when the cell is empty
Using FlexTable, which will be translated into table on the browser
later on on production will not show the border if the cell is empty i
guess, applying this:
.borderTop {
background:#FF;
border-style:solid;
border-width: 1px 0px 0px 0px;
border-color: #00;
}
will show a top border in Safari for example, but will not show it on
both FF and Opera (I didn't check with IE) if applied to an empty cell
on FlexTable. Is there a solution to this problem?

Re: docs discrepancy ???
Transitional means 'transitional'. It differs depending on the html version. '4.01 Transitional' means 'contains all HTML elements and attributes, including presentational and deprecated elements (like font). Framesets are not allowed.' But... !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional// EN ...will trigger quirks mode in newer browsers and older browsers just have quirks anyway. Although not the same quirks as each other, of course. Personally, I use !DOCTYPE Common PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' ' http://www.w3.org/TR/html4/loose.dtd' which will give you the 4.01 Transitional behaviour mentioned above in almost all browsers - all the important ones, anyway. HTH Ian http://examples.roughian.com 2009/6/20 Robert Lehr robert.l...@gmail.com FYI, there appears to be a discrepancy in the docs w/rt to the doc type specifying Transitional denotes Standards mode or Quirks mode. Which does it denote ? Note the following from GWT docs. From http://code.google.com/webtoolkit/tutorials/1.6/create.html - To provide better cross-browser compatibility, GWT sets the doctype declaration to HTML 4.01 Transitional. This sets the rendering engine to Standards Mode. If you remove this line, the page will be rendered in Quirks Mode, ... So - TRANSITIONAL denotes STANDARDS mode. From the comments in the host page auto-gen'ed by webAppCreator - !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional// EN !-- The HTML 4.01 Transitional DOCTYPE declaration-- !-- above set at the top of the file will set -- !-- the browser's rendering engine into -- !-- Quirks Mode. Replacing this declaration -- !-- with a Standards Mode doctype is supported, -- !-- but may lead to some differences in layout. -- Or - does TRANSITIONAL denote QUIRKS mode ? -robert --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to retrieve EntryPoint object?
Not really. The EntryPoint class is not really a class, but a script that is run to bootstrap your application. Any other use of the EntryPoint is a little bit of an abuse of the concept. It is possible to provide a global point of access to the EntryPoint using the Singleton pattern, but global visibility is almost always a bad idea.

Re: Container managed security and time-out of the webapp.
Thanks for your quick response and elaborate answer, Braheem!
I've tried a servlet-filter, but that didn't work for me since my
security constraint protects EVERY possible url within my app, see
following URL-pattern:
security-constraint
web-resource-collection
..
url-pattern/*/url-pattern
I guess I'll have to make this more fine grained, and put the servlet
filter servlet in an unprotected area.
Ciao,
Willem

ValueChangeHandler should be parameterized in the Javadoc of Hyperlink
Hi
ValueChangeHandler is a parameterized interface.
Hence, I think the example given in the Javadoc of Hyperlink should be
changed from:
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/user/client/ui/Hyperlink.htmlpublic
class HistoryExample implements EntryPoint, ValueChangeHandler {
...
public void onValueChange(ValueChangeEvent event) {
...
}
}
to the following:
public class HistoryExample implements EntryPoint,
ValueChangeHandlerString {
...
public void onValueChange(ValueChangeEvent event) {
...
}
}

The problem is when tested in hosted mode, the hyperlink stops responding
after the 1st time:
1) Login button is clicked, show logout hyperlink
2) Logout hyperlink is selected, show login button
3) Login button is clicked, show logout hyperlink
4) Logout hyperlink is selected, and NOTHING happen here!
Do you have any idea of what could be the problem?

Re: Hyperlink is not working after 1st try
2009/6/20 hezjing hezj...@gmail.com Do you have any idea of what could be the problem? Yep. You have a valuechange listener. i.e. it gets called if the value changes. The first time you click it, the value changes from nothing to 'logout' The second time you click it, it is already showing 'logout'. No change.

Re: Hyperlink is not working after 1st try
The first time you press the hyperlink to logout, there's a new
history item added of that name. The second time you press it, the
current history token is still logout, so it does nothing.

ToggleButton cannot be clicked again
Hi! In my project I have a ToggleButton. When I have clicked on it I have to move the mouse out of the button to click it again (toggle it), otherwise it simply ignores the next clicks. Btw: After the click a RPC call is started and depending on its result some actions in the GUI are performed. I use GWT 1.6.4. Does somebody have an idea how to solve this problem?

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)
As I myself didn't understand it completely either, I build a little testapp for it. And it was at the same time, my first blog post :) check it out: http://www.webspin.be/2009/06/learning-gwt-managing-events-with-eventbus/ On 20 jun, 00:21, Ian Bambury ianbamb...@gmail.com wrote: The PhoneEditor doesn't need the event bus since it doesn't respond to any events. The ContactWidget needs the event bus in case the details change in real time, then it can update itself. If you (the user) want to change the phone number while you are looking at the contact details (the ContactWidget is the view) then you use the PhoneEditor (which shows the PhoneEditWidget). Basically, you're looking at a phone number display which will update if the phone number changes. If you want to change it, you get a popup editor that lets you do that. The phone number display subscribes to updates so it will be up-to-date. The popup editor gets populated and then you edit it. You don't want the popup to update while you are putting the new number in so it doesn't do the update thing. So you are displaying the actual phone number, you decide to update it and get the popup. You put the new number in the popup and submit it (the PhoneEditor knows how to update, it was passed the rpcService). The data (i.e. the model) gets updated and feeds the change back. This feedback is to the event bus which fires an event to tell every interested widget that the phone number for contact nnn has changed. Including the display you were just looking at. The way they have done it in the presentation is 'optimistic'. I.e. they update the screen immediately, without waiting for the data to do the round trip. If the update fails and the resulting error doesn't get back, then your screen is showing different data to the model. Ideally, you should change the phone number label to 'updating' and let the feedback put the new number in there. That way the screen has more of a chance of showing the right information (there's still a chance that the update works and the data doesn't get fed back, but at least then the label shows 'updating' rather than out-of-sync information. I rather suspect that hasn't clarified anything :-) Ian http://examples.roughian.com 2009/6/19 Ben benzhe...@gmail.com Finally found a thread talking about this presentation. It is very interesting for me as well. Thomas, you mentioned slide #73, actually I have some question about this. In this slide, from my point of view, both PhoneEditWidget and ContactWidget are just Views in MVP. Phone Editor is Presenter in MVP. So is ContactViewer a presenter as well? If so, I understand that it passes Event Bus into Contact Viewer, why it doesn't pass the same Event Bus into PhoneEditor? For me, I am still not very clear about how this event bus works.

For my part, I was pleased to see it as a best practice, as that's what I'm thinking about for nearly a year (would require a huuge refactoring of our app, so it's still just an idea floating in the air) (I didn't watch the video, just looked at the slides) From what I can tell the idea is that UI widgets requiring data from the server are able to fire off requests for some form of data like void getTransactionsForAccount(Account acct) then at some unknown later time (ms to seconds ussually) when a response comes in from the RPC call the eventbus is what actually directly recives the data and then it is dispatched Well, not necessarily, though yes, that's what they said at Google I/ O. One of the reasons is that there are probably more than a single place where you use that same data in your app (in GMail it could be the list of mails, the unread count for the box and/or label(s), and the conversation view of course). That way, all places are informed, wherever the initial request came from. Client UI: Hey call some RPC method with these parameters, my AsyncCallback is this EventBus thing ...some unknown time passes while the server does magic... Client Event Bus: A response came in of type X/Y/Z I should fire an event to all interested parties Client UI: According to this event I just recieved some of my UI code needs to change A few things are still very hazy for me... 1- What is missing here is when would the Client UI typically subscribe/unsubscribe from the event bus. If this were a desktop application I would simply use weak reference so I would not have to unsubscribe my UI manually

Re: Hyperlink is not working after 1st try
To close this thread, the solution is to rest the history token by adding

History.newItem(login, false);

Re: maps-api Directions color
Ok. It is more work to set it up and add the items to the map, but if you
look at the DirectionsResult object and the corresponding classes to create
a directions query, you'll see that there is an option to return the
polyline object. You can set the style on that object to change its color
and then manually add it to the map.

Hi Eric,
thank you for your answare.
I 've tried what you tell me, but setting a style to a

My purpose was another:
change the color of the tour on the map.
The default color is purple:
for example:
http://maps.google.com/maps?f=qsource=s_qhl=itgeocode=q=da+giubiasco+a+locarnosll=37.509726,-95.712891sspn=42.145189,79.101563ie=UTF8ll=46.186961,8.926048spn=0.145225,0.30899t=hz=12
if you open this map, you see that the color of the street to do, is
purple...
It's possible to change this color?

I think you could do this with CSS. Put a style on your DirectionsPanel
with
directionsPanel1.setStyleName(directions1);
directionsPanel2.setStyleName(directions2);
.css file:
.directions1 {
background-color: #eee;}
.directions2 {
background-color: #fee;
}
Or, if you wanted to affect some elements specifically in a different
way, you could use CSS descendent selectors:
.directions1 td {
color: red;
}
.directions2 td {
color: green;
}
Look at the DOM using firebug or another tool to see which elements
and classnames are are defined inside the Directions Panel.

I have searched in the api but not found...
my problem is that i have to display more than one tour, and it
would be nice to show these tours in different colors.

I'm using GWT1.6, error occurs in FF and Chrome (didn't check any other
browser yet), and I call addSiteFriends(myJsObj) from javascript in the
html.
EntryPoint does contain other stuff... so mainPanel is added to RootPanel...

Here's the error as reported by Firebug:

I am calling a Java method from Javascript
Here's the GWT code:
public class Caribbeanvisit implements EntryPoint {
/**
* This is the entry point method.

final VerticalPanel siteFriendsPanel = new VerticalPanel();
public void onModuleLoad() {
exportAddSiteFriends();
mainPanel.add(siteFriendsPanel);

public void addSiteFriends(JsniPerson[] jso) {
// fyi: JsniPerson extends JavascriptObject
for (JsniPerson person : jso) {
final HorizontalPanel hp = new HorizontalPanel();
final Image thumbnail = new Image(person.getThumbnailUrl());
final HTML txt = new HTML(person.getDisplayName());
hp.add(thumbnail);
hp.add(txt);
this.siteFriendsPanel.add(hp); // --- error happens here
this.siteFriendsPanel.add(new HTML(TEST)); // --- error happens
here also
}
}
}
Any ideas?

Re: VerticalPanel error
Found fix.
Making the verticalpanel's static solves it.
