Re: Chrome 24 and GWT

I don't have those resources, but I'm aware that it's what I should do. It's actually even worse: I'm paid to build webapps, not maintaining them. We're not proactive on browser changes because that's not part of the deal with our customers, but we're generally in the situation of shipping a fixed version (provided there's an easy fix or workaround) in a matter of hours. Once the warranty period is over however, I bet nobody does testing either and fixes can take ages. BTW, I also know there *are* people in the real world of enterprise software who *do* end-to-end testing, either using Selenium/WebDriver on a cluster of servers, or using SaaS such as Sauce Labs, driven by a CI server (Jenkins/Hudson, TeamCity, Bamboo, etc.) to be run on each commit and/or nightly. The root of the issue is that most people (IT deps mostly) ask for webapps rather than native apps (generally to replace native apps) for bad reasons and/or without understanding the consequences. Stable software should remain stable. If a customer upgrades his version of Windows, I shouldn't expect the new version to suddenly start working strangely because of a radical change in how animations are rendered. A similar concept should apply for web browsers. ROTFL! Are you talking about that Windows OS that breaks its WebDAV support in almost every new version or service pack, and even sometimes hotfixes? http://www.greenbytes.de/tech/webdav/webdav-redirector-list.html(I had to do an emergency patch in a server after the SP1 was deployed on Win7 this fall; BTW the webapp is 4 years old 'cause nobody allocated the budget to maintain and update it, not even with security fixes: “if it ain't broke, don't fix it”, BS; this is the state of software in the real world of enterprise software: zombie servers on a drip of emergency fixes to keep them alive) The one OS for which every IT department delays hotfix/SP deployment by fear of breaking their payroll or LoB apps? (which is probably the main reason there's still so many IE7 and IE8 out there –last year I would even have added IE6 to the list–). But again, we're talking here about a bug in GWT, in the use of a beta API. And that bug was fixed long before the change in Chrome reached end users.

Re: Chrome 24 and GWT
Yes Thomas, you are quite correct on two very good points, firstly that my customers are technically waiting for ME to upgrade to 2.5 and secondly that I SHOULD have been using an SCM and/or should have been taking regular backups... thats TOTALLY on me.. I have grown organically and was not even aware of how to use an SCM when I started development back in 2009, its been a learning experience the whole way through, and the reason I chose GWT as a development platform was so that I would not have to worry about testing against all the possible browser options. (Yes it quickly became obvious that Google do not take ALL the cross browser pain away!) I actually dropped my pc (attached to my backup device, while backing up and managed to destroy both beyond recovery - I spend over £500 trying to recover the data) I am working through the process of rebuilding the product since my last cloud backup in April 2012, but that was built in GWT2.4. So yes, I cant branch my SCM (didnt have one) and I didnt plan for that eventuality. I am NOW using GIT and BitBucket and SugarSync, DropBox and Google Drive to back EVERYTHING up constantly! I relied too heavily on Google taking care of all browser compatibility and I didn't fully comprehend the dangers of not being absolutely meticulous... totally my fault on those two issues, but still its annoying that an automatic update to Chrome has broken my application. Sure, I should be able to fix and be agile and maneuver but currently I'm not, so I am stuck in the short them having to ask my customers to go use firefox or safari or god forbid even IE (v8 at least!!)

And you didn't plan for that eventuality? and Im getting complaints from my customers I have had to tell them to use Internet Explorer while we wait for Google to fix it!! You mean while they wait for you to update, right? I don't get why people get angry here: there was a bug in GWT, it was fixed 8 months ago in trunk and was released nearly 3 months ago (before users on the stable channel of Chrome could even notice). There's an easy workaround too for people not ready to update to GWT 2.5. So what's the problem actually? You didn't test your apps with beta or dev versions of your browsers (that gives you 6 to 12 weeks to fix issues before your users can notice), you're 3 months late on updating to the latest stable release of GWT *and* you cannot deploy an updated version (recompiled with the workaround) quickly. You can blame GWT for using a beta, though rather stable, API (requestAnimationFrame) to smooth the rendering of your app and having made assumptions on the value it received as argument and the exact time it'll be called back, but GWT is not the only one to blame by an order of magnitude. The Web is a moving target: browsers update and can break your code as soon as you (or the lib you use) a) make assumptions on browsers behaviors, b) use beta APIs or c) use hacks or workarounds. When working with web technologies (whether it's GWT, jQuery or vanilla JS), it's very important to regularly a) test in beta or dev versions of your browsers, b) update to the latest release of the libs you use and c) be prepared to re-deploy quickly. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: clean compile gives the parameter is incorrect
OK, so in desparation, I went the whole hog and moved my SDK to C: \appengine-java-sdk-1.3.2 and w, its suddenly compiled successfully So there you have it folks, anyone reading this and seemingly only ever finding someone saying your classpath might be too long may find it helpful to simply relocate your appengine sdk to the root of your c:\ drive and see if that helps! Also worth pointing out of course that this is technically an appengine issue rather than a GWT issue, so thanks to everyone on this GWT forum for helping me fix this, I will now go and add this solution to my question on the GAE for java forum! Thanks all, J PS I never did figure out how to run anything off the command line, but im not going to bother now, until I find a need to think about doing that later!! PPS a summary for anyone reading this later who doesnt want to read all the thread: To find out the classpath used: In Eclipse select Debug view by going to Window|Open Perspective|Debug and then select the debug window by going to Window|Show View|Debug then right click the last item in the list shown and select properties I found that my appengine SDK path was being references about 21 times as: C:\Program Files\eclipse\plugins \com.google.appengine.eclipse.sdkbundle. 1.3.2_1.3.2.v201003241245\appengine-java-sdk-1.3.2 so I copied it to C:\appengine-java-sdk-1.3.2 And then linked to it by doing the following: In Eclipse select the Java view by going to Window|Open Perspective| Java and then select the project properties by going to Project| Properties then select Google|App Engine and click on Configure SDK's then click Add on the right hand side and select the path you just created eg C:\appengine-java-sdk-1.3.2 and add a Display Name eg Short App Engine SDK. Click OK as needed to close all the windows, and everything should start working again!!!

Google Accounts are killing my application!....
I have been trying to leverage google accounts for security for my users, but the way its working is really preventing useability within my application, its very frustrating Ive just spent the best part of the last week trying to get the google account login to work in an frame within my application. Ive run into a number of related issues (see other threads) which I have manage to work through finally. (Thanks to everyone who helped out and provided input) However, I have just tried clicking on the create an account now link which is what will be used by any new user who doesnt currently have a google account, but the account creation window has frame breakout code on it, which takes my users away from my application again, and then after clicking on the email link to confirm thier new account, the user is NOT taken back to my application but are just congratulated for creating a google account. The problem is that the user is then left thinking now what do i do? and several of the people we are talking to have just given up at that point! Has anyone else successfully integrated Google accounts into their applications? Should I create my own logins rather than using Google accounts? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Thanks gengstrand, Ill deal with your 3 options in turn: 1. official App Engine options a) use google accounts as a unified signon: This is how we are currently implementing, the problem is that if the potential customer/ user is not very technically savvy, and either doesnt have an email or only has a hotmail account, then setting up a google account is not at all straighforward and because it doesnt have any kind of API, it cant be integrated into your existing application, so the sign up and sign in processes are very disconnected from the non-google application. b) use google apps for your domain: This is a similar arguement for the above problem, fine if you are doing something inside your organisation, but if you are dealing with random basic internet users (eg everyone on facebook) then it is next to useless as an authentication option 2. The use of jBCrypt : This is fine for encrypting the password into the database on the server, but from reading a lot of other posts on this subject GWT does something funny when translating JBCrypt into javascript on the client, and renders it useless. 3. waiting for RPCAuth : This is no good for us, as we are currently live, and as i said above, Im looking for an inhouse alternative to google accounts as a unified login. It seems to me that Im still not getting a clear answer to my main question: Given that I cant use SSL or HTTPS and I dont want to use a 3rd party login system, how safe is it to just send passwords in plain text to the server and then use JBCrypt on the server to encrypt the passwords when storing it?

Re: username/password when using GAE
Ah, sorry Benjamin, my earlier reply to gengstrand was written before id fully taken in what your blog was saying. I cant be sure that you have indeed answered my question, as it will take me a little while to filter through your blog and understand it all, but it certainly seems to cover the majority of the points, even if it feels to me like you have slightly overengineered it for what I actually need. I forgot to mention on my previous post, that I have also played around with using a GWT Frame to contain the google account signup and google account login pages, but what Id like to be able to do is somehow set the URL of the page containing the frame from within the frame itself! Anyone know how to do that? I might post that separately after making sure it hasnt already been answered somewhere!

setting or refreshing the parent URL from within an iframe
My application requires a login to a google account. I have been looking at trying to do this login step within a GWT frame which works fine. The problem is that once that login has been completed my application then loads INSIDE the frame, I really want it to reload in the parent window. I have tried both the following: Window.Location.reload(); Window.open(http://www.google.co.uk;, _top,); but neither of them have the desired effect, If I press F5 it does exactlywhat I want it to do, even if the focus is on a text box within the frame. Anyone got any ideas, am I doing something wrong, is there a better way to do this? Thanks, John -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: setting or refreshing the parent URL from within an iframe
OK, I think I might have figured out what the problem is... when Im creating the frame Im trying to set it using the following line: The resulting URL is /_ah/login?continue=http%3A%2F%2Flocalhost %3A%2F so the problem is that it is stripping out the / myappname.html?gwt.codesvr=127.0.0.1:9997 part which then results in me running the last version of the application that I deployed to the web. Does anyone know why the version at localhost: is not the same version that exists at localhost:888/IDeBanet.html? gwt.codesvr=127.0.0.1:9997 or how I can force it to be the same without having to deploy each time?

Re: Duplicate RPCs in gwt + app engine -- why?
ah yes, ive had that one, i was recreating the dialogs and buttons each time, and then found id defined multiple on click events which all did the same thing, so that when the user clicked on the submit button, it actually initiated the same function multiple times! I also fell down the trap of forgetting that the RPC call was asynchronous and so sometimes there were actions following the RPC call which were being executed before the rpc had finished messy beginners mistakes!

Re: Hosted mode hanging 4 out of 10times
Just thought it might be worth mentioning that I have been having this
problem for about 4 weeks now... I was hoping it might be dealt with
in the lastest updates, but its still there!
Im using GWT with GAE functionality, my app is built up from the
original stockwatcher application.
I actually have periods of time when I get this problem over and over
and over again, but usually I find that it eventually sorts itself out
without me doing anything, I just keep trying to restart hosted mode,
and eventually it kicks in by going to the correct url
There are suggestions around (not sure if they are also in here) that
clearing the IE cache can fix this problem, and that worked for me for
a little while, but then it didnt work anymore, and after experiencing
the issue so many times, i now know that its just a waiting game.
However, I also find that closing eclipse down and reopening it seems
to clear the problem too, but then again that just might be due to the
time period it takes to shut down and restart (the ubiquitous have
you tried rebooting solution)
Cheers,
J

Re: dialog box background - BUG?
OK so this bug seems to relate to a dialog box, containing a
FlexTable, when you use the addStyleName operator rather than the
setStyleName operator
If you create a basic GWT project and add the following code just just
after the line which adds the send button into the HTML page
( RootPanel.get(sendButtonContainer).add(sendButton); )
final Button TestButton = new Button(TEST,
new ClickHandler() {
public void onClick(ClickEvent event) {
final DialogBox TestDialogBox = new DialogBox();
TestDialogBox.addStyleName(TEST_DIALOG);
final FlexTable TestFT = new FlexTable();
final Button TestCloseButton = new Button(Close);
TestFT.setWidget(3,1,TestCloseButton);
TestDialogBox.setWidget(TestFT);
TestCloseButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
TestDialogBox.hide();
}
});
TestDialogBox.show();
}
});
RootPanel.get(sendButtonContainer).add(TestButton);
Then add the following in the CSS file:
.TEST_DIALOG {
background: red;
}
Then you will see this bug when you run the project and click on the
TEST button

Re: dialog box background - BUG?
Hmmm, not sure I ever would have figured that out on my own, Ive only
been doing web application development for about 2-3 months, so this
is all new to me.
You were correct in your assumptions, and that makes sense why the
problem only happens when you add a stylename, as using the
setStyleName would override the gwt-DialogBox Style.
Also odd though that the problem goes away when you use
dialogBox.setWidget(dialogVPanel); which must mean that the dialog box
width automatically shrinks to fit the vertical panel, but doesnt when
the widget is a flextable.
Thanks for the tip about firebug, I downloaded that for another
purpose a while ago, and didnt know that you could use it in the way
you have described below, so I will have a look at that, not least as
it might help me dissect and understand whats happening with GWT
unther the hood a bit better
Thanhks for your help and input, hopefully this will be a useful entry
for anyone else with a similar issue :D

John,
I'm assuming that by basic GWT project you mean a project created
with the New Web Application Project wizard in the Google Plugin for
Eclipse, since that seems to fit with your description. If that
assumption is correct, then you're not looking at a bug at all. The
CSS file created by the wizard sets a width of 400px on DialogBoxes:
.gwt-DialogBox {
width: 400px;
}
You have a 400px-wide dialog with a smaller table inside it, allowing
the background to show through. I'm sure you could've discovered that
for yourself. If you'd really stripped things down to the smallest
possible reproduction case, you would've found that the problem
disappeared when you removed that CSS rule. You also could've
discovered it by examining your application in a DOM inspector such as
the Firefox plugin Firebug.

On Sep 21, 4:03 am, Bulat Sirazetdinov bula...@gmail.com wrote:
You should do it this way:
At first you'll need to create a class that implements
HasValueChangeHandlers interface. It is because of the fact that
ValueChangeEvent.fire() method requires a class that implements
HasValueChangeHandlers interface passed in a first parameter.
So let name that class MyHandlers (see below).
Then you should get an instance of MyHandlers class:
---
MyHandlersString exampleHandlers = new HandlersString();
---
and register ValueChangeHandler objects in that instance:
---
exampleHandlers.addValueChangeHandler(someHandler1);
exampleHandlers.addValueChangeHandler(someHandler2);
exampleHandlers.addValueChangeHandler(someHandler3);
---
Now you can fire ValueChangeEvent to all handlers that you've
registered in exampleHandlers object:
---
ValueChangeEvent.fire(exampleHandlers, text);
---
MyHandlers class declaration:
-
public class MyHandlersI implements HasValueChangeHandlersI {
private final ListValueChangeHandlerI list = new
ArrayListValueChangeHandlerI();
public void fireEvent(GwtEvent? event) {
if (event instanceof ValueChangeEvent) {
for (ValueChangeHandlerI handler : list) {
handler.onValueChange((ValueChangeEventI) event);
}
}
}
public HandlerRegistration addValueChangeHandler(final
ValueChangeHandlerI handler) {
list.add(handler);
return new HandlerRegistration() {
public void removeHandler() {
list.remove(handler);
}
};
}}

Hope that helps.

ValueChangeEventString.fire( changeHandlers, foo);

rabbit hole that I'm frankly not experienced enough to deal with

HTTP POST on the server side?
Please excuse the newbie wording below, Im really not sure how to phrase this problem correctly, which is of course causing me problems with trying to find a solution by searching online, as I dont really know what it is that i need to do, but I think its an HTTP POST (but it could be send/get/submit/request?! as Ive seen all these terms used when hunting around for a solution!) Ive looked around as much as I can though and as is often the case cant seem to find any working examples of what I need to do which is to call a 3rd party website via an HTTP call from the server side of my GWT/GAE application. Essentially the following code snippet does the job on the client side (ive changed the parameters to protect confidentiality): String SendText=http://www.services.dynmark.com/ HttpServices/SendMessage.ashx? + user=username + password=password + to=447765111222+ from=447765222111 + text=MESSAGE_TEXT; Anchor SendMessageLink = new Anchor(Send Message); SendMessageLink.setHref(SendText); RootPanel.get().add(SendMessageLink); when the user clicks on the link though, it takes them to an XML result page with a reference number embedded. Obviously i dont want that to happen, i need to capture the reference number so I can then make a different HTTP request to get the status, and I dont want the user to see the HTTP text (password) or to be redirected to another website. Ive then tried to use the Requestbuilder function (class/widget?) of GWT, but thats when I run into the same origin policy security restriction (http://en.wikipedia.org/wiki/Same_origin_policy) Reading around on the internet, it seems that the only way to achieve what I need is to run the HTTP post from the server after an RPC conection. I have tried to implement this, but have found no working examples to figure out how to achieve this. I have tried to simple copy and paste the Requestbuilder code into my server functions, only to have the following error appear on the eclipse console: Caused by: java.lang.UnsupportedOperationException: ERROR: GWT.create () is only usable in client code! It cannot be called, for example, from server code. If anyone can give me some help and advice on this topic, then I would be very greatful!

I am certain that this is a horrible way to achieve the result, but it works OK, so for now Im going to live with it.

Hi Frank and Trevis, you are both correct, and I guess I should apologise to some extent, I was just throwing the question out there to see what kind of a response I got. I am happy to drop this thread now and concentrate on specific GWT questions. I have been burnt several times over the last six months, both with commercial organisations and individuals who have promised the world and then simply not delivered.

Frank, I used to be a programmer, but have moved away from it over the years, and have been forced back into it, due to being unable to find anyone else who can do a good enough job for me. I dont want to be doing the programming, I am an ideas man, so if you have any suggestions as to how i can find competent developers without having to pay them for 2 months work before finding out how good they really are, then I am all ears!!

Can anyone help me please?! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to fire events registered with a HandlerManager?
I sitll cant work out from the code in this article, how to fire an
event:
final ListBox dropBox = new ListBox(false);
dropBox.addItem();
dropBox.addItem(a);
dropBox.addItem(b);
dropBox.addItem(c);
dropBox.addItem(d);
dropBox.addChangeHandler(new ChangeHandler()
{
// @Override
public void onChange(ChangeEvent event)
{
switch (dropBox.getSelectedIndex()) {
case 0:
ApptPrice.setText();
break;
case 1:
ApptPrice.setText(8.50);
break;
case 2:
ApptPrice.setText(9.50);
break;
case 3:
ApptPrice.setText(10.50);
break;
case 4:
ApptPrice.setText(11.50);
break;
default:
ApptPrice.setText(should never see
this);
break;
}
}
});
dropBox.setItemSelected(setitemtoselect, true);
dropBox.fireEvent(onChange);
Its this last line I want to implement, Im setting the selection
programattically (based on selections elsewhere in the code) and i
need to fire the onChange event because as stated in the javadoc:
Note that setting the selection programmatically does not cause the
ChangeHandler.onChange(ChangeEvent) event to be fired.

Thanks Thomas... That and gazing wisely (or at least trying to give

ValueChangeEvent.fire( this, theNewValue );

..which looks like it should work. Still fuzzy on why the widget can't
manage an independent list of handlers under the hood, and the event
typing system still has me baffled, but this'll get me past the puzzle
box that kept me busy yesterday and seems less complex than what I was
doing... Thanks for your help!

Hello -
So, I've got a composite that has something like this inside it...
private HandlerManager changeHandlers = new HandlerManager( null );
public HandlerRegistration addValueChangeHandler(ValueChangeHandler
handler)
{ return changeHandlers.addHandler(ValueChangeEvent.getType(),
handler); }
You shouldn't ever instantiate a HandlerManager (except if you use one
as an event bus; but that's another story and at least this rule is
true for widgets); just call the Widget#addHandler(...) method.
public HandlerRegistration addValueChangeHandler
(ValueChangeHandlerString handler) {
return addHandler(handler, ValueChangeEvent.getType());
}
...and somewhere down the pipeline, I want to actually fire off an
event to anyone who registered a handler when the composite decides
it's represented value has changed and wants the rest of the world to
know. However, the syntax for actually constructing and firing the
event off has got me pulling my hair out.
I've tried variants of sending the event through the change
handlers...
changeHandlers.fireEvent( new ValueChangeEvent(foo) );
changeHandlers.fireEvent( new ValueChangeEventString(foo) );
...and using the static fire() method in the event class itself...
ValueChangeEventString.fire( changeHandlers, foo);
...and Eclipse complains loudly about all of these constructions. I
mean, I know this can't be that hard, but I can't find any good
examples of things like this using the new (GWT 1.6 or later) event
handlers, and reading the code sends me down a DOM event/Java generics
rabbit hole that I'm frankly not experienced enough to deal with
yet...
Any help appreciated!
ValueChangeEvent.fire(this, foo);

Re: Offline GWT Applications
Great Question, Im doing a similar thing, but Im using the App Engine, but at present I cant get the datastore access to work, Ive been stuck on that for 3 days now, and I only wanted to do that so that I could move on to testing gears outhowever it looks like that might be a waste of time anyway! Thanks for the heads up and saving me some time... Still want to get the datastore thing working though, thats reallly frustrating me! On Aug 3, 4:18 pm, Dominic Holt domh...@gmail.com wrote: Greetings all, I am currently building a GWT application that functions entirely offline (as in, never connects to the internet to update, sync, what have you). In a normal web application, you can typically run your application offline just as well as long as you use an application server that you have deployed your app in and assuming you have local network access to the application server. The problem inherent with GWT is that you must use GWT-RPC in order to call the server from the client side in order to do interesting things. Normally this would not be a problem, it would just be a server call and would make use of the local application server, but GWT insists on having a connection to the internet to make an RPC call (and I'm having a hard time understanding why this is a good idea). At any rate, Google's answer to this problem seems to be to use Gears to stick everything in a database. I've accomplished reasonable functionality by creating separate java projects that do interesting things, which access the Gears SQLite database used by my GWT project. Essentially the GWT project has to stick things into the database, the other projects have to read these inputs out of the database, perform magic with them, and then put them back in the database so that the GWT project can read them again. Unfortunately, this method is becoming increasingly cumbersome, especially with the limitations of SQLite and how you can only update so often without the database locking. Is there a way to fake an internet connection for GWT so that GWT-RPC calls will work offline? Is there a better method?
