Re: How to disable menu items?
Hi Rob, I think you got me a little bit wrong: I don't want the menu to handle the logic. I can handle the logic my self. But I need to tell the menu that it should show (paint) a menu item as disabled. Give me a method like this and I am happy: MenuItem.setEnabled (boolean enabled); Well, the recommendation for gwtlib from Alan shows that this must be implemented already. Then it must also be possible for me to do this "by hand", without using an additional library. But how? It would be fine if someone could tell how this can be done.

AE / GWT Newb: How to do RPC Call with my own return type?
Hey guys, I've been mess making an app for a while now, and I've finally got something that is able to save an entity on the server. That entity (to keep it simple) is of type Event. It has 2 Date objects: startDate and endDate. I understand how to do queries and what not, but what I found my program encountering issues with is in my method within the ServiceImpl, getEvents(), it's having a difficult time distinguishing between my client side Event object and my server side. This creates issues when I try to have my return type as List. How should I be handling this? Does the client side Event object need to be serializable? I've tried this, still without much luck. On the client side Service, and ServiceAsync classes, should I be declaring the types through the server side object? Example: public List getEvents(); or should I perhaps be doing the same thing, but with the client side on the server? I've tried both of these, but can't seem to get it to be happy with whatever I put. Any direction in this would be greatly appreciated!

Re: Problem with UTF-8
One simple way to check if it is Java/GWT code or the browser is to
add some UTF-8 chars straight to the html file. If that is working
correctly then it must be either the Java file isn't UTF-8 or
something else is wrong. Eclipse allows you to change the encoding of
files through the properties menu.

Re: Error on execution
mm, I have never used Netbeans.. In general that problem happen when you run an app that isn't compiled. When you run development-mode it generated a folder in the war directory if it didn't exist. And if you try to run the app without development-mode before compiling you will get that alert. If your app works on development-mode there is something wrong with the compiling process. If you see the alert in development-mode (I don't know if that even possible).. I don't know what you can do :P Try to describe better the situation. 2010/8/3 Diego Venuzka > Hi Gal! > Well, i'm using Netbeans to build my project, and i don't found the war > directory.

[Help Needed] GwtCreateResource -- how do I get this working for me?
Ok, here's the example code:
---
public class Settings {
/**
* The size of the blocks to draw on the client-side, in pixels.
*/
public static final int PIXEL_SIZE = 5;
/**
* The length of the array to draw on the client-side.
*/
public static final int MAX = 100;
/**
* The HTML ID for the canvas that is drawn.
*/
public static final String CANVAS_ID = "drawingCanvas";
public static final String APP_ID = "appPanel";
public static final String CLIENTID = "clientId";
public static final String FUNCNAME = "funcName";
public static final String CODE = "code";
public static final int LIST_SIZE = 200;
public int listSize() {
return LIST_SIZE;
}
public int mainSize() {
return canvasSize() + LIST_SIZE;
}
public int canvasSize() {
return PIXEL_SIZE * MAX;
}
}
public interface Resources extends ClientBundle {
@Source("ShowSort.css")
Style style();
GwtCreateResource settings();
public interface Style extends CssResource {
public String customFlowPanel();
public String algobutton();
public String notlive();
}
}
---
The problem I am having, is it is failing to provide access to the
methods in my Settings class, I have three defined, with zero-args. I
am trying to access the canvasSize() method within the above uibinder
XML file, and compilation is failing with the following:

---
I'm at a loss, it says there is no "no-arg" method named canvasSize in
the GwtCreateResource type. I must be doing something wrong here.
What I am trying to do, is have the parameters I define in
Settings.java to be able to be accessed through the ClientBundle,
eventually so then I can use them within my own defined CssResource
(the ShowSort.css resource in Resources.java above), through the use
of the value() function in CSS, as defined here:
http://code.google.com/p/google-web-toolkit/wiki/CssResource#Value_function
I want to programattically be able to define/set some of the
parameters used in the CSS code, with the same Settings class I have
being used for my server & client code currently. But for me to be
able to make this work, I need to be able to have the Settings values
be available in the ClientBundle that contains the CssResource, from
my understanding. This doesn't seem to be working... I thought
GwtCreateResource<> was the correct thing to use, but it is failing.
Please help :)

Re: GWT 2.0, Maven, Google eclipse and TOMCAT, why didn't google build maven support?
The problem is when you try to bring maven, tomcat and google plugin
together. I have hacked my way around with jetty and was able to get
it working at some level.
The problem is there is zero documentation on getting things working.

The maven-gae-plugin mvp archetype generates a very informative

I would encourage anyone who has it working to post their pom here!

[I don't know why anyone in 2010 still would want to reinvent the
wheel and expect everybody else to learn how to use their unusual
build system when Maven offers a reasonably well working alternative
that most people are already familiar with. Sadly, most people simply
do not appreciate the importance of the build step ("Do we really need
a separate build? Why can't we just build in Eclipse?"). :-) ]

I use Jetty instead of Tomcat but other than that: yes, it's possible.
It's not easy, though. Luckily, most of the hard work has been done
already by the good folk at Spring Framework's Roo. So what I did was:
install Roo, create a very basic GWT project (Hibernate, Hypersonic in
memory, one entity + GWT setup) and then remove any reference to Roo
and most of the Roo generated Java (use common sense and your own
judgement). That will leave you with an almost functional Maven
project (you should be able to take over from there).
This is not a perfect result but it will get you close enough for you
to fix the things that don't work. There are, however, still a few
caveats.
1. You'll have to go out and find all the various repositories that
offer you the (GWT related) Maven artifacts that you need and put
those repositories in your settings.xml. This is especially true if
you want to use any of the GWT-* projects.
2. Given the poor Maven support, the POMs Maven downloads will usually
not have any references to transitive dependencies. You'll have to add
required transitive dependencies to your project's pom.xml explicitly.
3. Roo uses AspectJ. I left in AspectJ support because I thought it
might be useful later on but if you want to remove it, you'll have a
bit more work to do.
4. Roo uses GWT 2.1.0-M2. I don't know if downgrading breaks anything.
The end result follows Maven directory rules (no silly 'war' directory
in the project root directory), it builds a proper WAR (although I
haven't tried running it), and if you leave "mvn gwt:run" running any
changes you make in Java or other files will be picked up
automagically.
P.S. Please note that the project built by Roo isn't bug free.
Strangely, if you create the same project but use Spring MVC (e.g.)
instead of GWT then it all works perfectly. This doesn't affect the
Maven setup, though.

Re: Problem with UTF-8
Thank you David,
I just did what you wrote and deleted the Java file and paste the code
in the new Java file again and the same with the HTML file. I checked
the properties and both had UTF-8 already but without success. On
the browser the Swedish letters still replaced with other
characters... My browser settings is on UTF-8 too!
Do you have any other suggestions?

Re: Client side code breakpoints stop to work after user was redirected to the guice servlet page, and the back to the GWT page.
Hi, it looks indeed like this problem has to do with forwarding. However, I'm surprised that adding the gwt.codesvr parameter to the URL did not fix the problem. A couple of questions: 1. What browser are you using, and does this happen on multiple browsers? (This could point to a browser-specific-plugin problem) 2. If you accept that GPE creates a new session, do you actually hit the breakpoints? Also, does the app work fine in compiled mode? If you use something like Firebug, do you see whether the whole GWT app is loaded again after the redirect from the login? kathrin On Tue, Aug 3, 2010 at 7:58 AM, semirenko wrote: > Hi, guys! > > I am using GWT 2.0.4, Ubuntu 10.04, JDK 1.6.0_20. > I am trying to implement Google OAuth in my GWT application.

setInnerHTML + Event-Handling

(MyElement) ...some text ... (MyElement) ... I tried to build the content as a html string and apply it with DOM.setInnerHTML(content). It looks pretty well but removes event handling. (MyPanel) ...

Re: How to disable menu items?
So what you are saying is that you need a way for the menu to detect which user/user group is looking at the menu. As you are already saying you have user groups it should not be to hard to inform the menu about the user group that is trying to open it. Once the menu knows which group is trying to open it it can use internal hard coded or externally read logic to decide what fields to render and how to render them, what events to attach to the elements and so on. I would simply hand the menu a variable/object that identifies the user group accessing it. Then the menu logic can deal with the rest. I would though use an external location to store the logic for the menu so you can easily update it should you need to add a new group in the future. I hope that helps a bit...

Re: How to disable menu items?
Thank you, but shouldn't GWT itself provide a mechanism to disable menu items? Using an additional library is not the problem for me, but using an additional library because of such a small functionality that should be present in any menu implementation is a problem for me. As a consequence I would end up in about a dozent libs... Isn't there another solution? Why is this missing?

SplitLayoutPanel.animate()
Hi all,
I am trying to have an animated effect that simulates 'maximization'
with SplitLayoutPanel, in which clicking on the 'north' widget will
maximizes it at the expense of 'center' and 'south'
.animate() works only for the first time of showing the widgets, but
is ignored afterwords.
Even overriding animate(int, AnimationCallback) with a hardcoded value
does not have an effect.
Can .animate() be used for that scenario?
Thanks a lot for your help.
public void onModuleLoad() {
final SplitLayoutPanel panel = new SplitLayoutPanel() {
@Override
public void animate(int duration, AnimationCallback
callback) {
super.animate(5000, callback);
}
};
final HTML center = new HTML("Center");
final HTML south = new HTML("South");
final Button button = new Button("Hello");
button.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
panel.remove(south);
panel.remove(center);
panel.remove(button);
panel.add(button);
panel.animate(5000);
}
});
panel.addNorth(button, 50);
panel.addSouth(south, 50);
panel.add(center);
RootLayoutPanel.get().add(panel);
}

JSONP callback with unique callback names?
Hello forum! A couple o' questions: Q1) How to cancel JS Timer? Given that I have very basic expertise in JS, I am not sure on how to cancel a scheduled timer in Javascript? I ask this because, I am creating an application which is based on the 'Stockwatcher' example using JSONP async call back mechanism. i.e you start a timer to wait for response from a remote server right before you attach the script tag, and then fetch/execute the URL and hope to get response from the server asynchronously. I understand that there are two possible outcomes now: - The server responds in time and hence the callback function is invoked correctly with some information through HTTP to client to handle and parse. or - The server fails to respond in time and hence timer expires. Seconds case is easy to handle since flow of control is pretty straightforward. Now what about case one's timer? What if I don't want to bother handling timer expiration in case when valid data is returned? Is there a way I can preempt the timer from expiring and kill it every time I get a valid response instead of letting it die of natural causes? I tried cleartimeout(t); but doesn't seem to work :( Q2) Why use unique function callback names for JSONP? On a similar note, I've noticed that every manual and tutorial on JSONP or GWT/JSONP talks about using unique callback names for fetching data back-to-back. Consider a simple example: d1, d2 and d3 are 3 daemons that poll for certain type of data repeatedly from a server. Let's say d1 polls for temperature, d2 polls for voltage and d3 polls for current. On the server side, JSON objects can be fetched appropriately by wrapping callback function names dynamically and returning it to client. My very first implementation of my GWT application did exactly this - I used a ever incrementing integer counter starting at 0 appended with daemon name as 'unique' callback function name for every data server call. eg: I poll for temperature data every 10 seconds by using return callback function names 0d1, 1d1, 2d1 etc, voltage data is retrieved by using 0d2, 1d2, 2d2 etc and current as 0d3, 1d3, 2d3 etc. This works perfectly fine. However, I then thought as to why it is necessary to have unique callback names for data polled by the 'same' daemon over and over again. That is why not I just use d0 for temperature, d1 for voltage and d3 for current all the way through my polling cycles instead of appending counter value to make multiple unique callbacks within every daemon? Especially because I am not expecting parallel results back from same daemon at any given time. My cycle is pretty much: ask for data, start timer, get data (either valid data before timer expires, or, NULL if timer expires). Once I handle the return data, I call my function to go fetch info. again, hence making it a sequential access loop. This is true for every daemon. Are unique callback function names in this case necessary? Extra information: My motivation to use same callback function names within every daemon arises due to the fact that I have a set of processes running on my server side which already output JSON objects padded with callback names as in-memory (cache) files that look like - callback123([JSON]); And since the format is ready-to-eat by the GWT client (if there is a corresponding callback123 JS callback function defined that is), I would hate to do any cgi-bin processing on the server side to take JSON objects every time and pad them with different callback function names every single time for the same purpose (temperature, voltage or current polling). Also since cgi scripts are expensive on resources, I opt not to do any processing on the JSON files. I cannot have additional servlets or other containers installed on my 'embedded' server and hence I am limited to what it has to offer - a basic web server with a web-root and cgi-bin. I am able to create a symbolic link to /tmp (tmpfs) in my WEB-ROOT. /tmp is where all the JSON files are populated periodically. These are then read like regular text over HTTP from my client browser code. To my surprise it worked beautifully, however I can't seem to get past the first callback! I ruled out a browser caching issue too. Help! Thanks! Iggy -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT + Hibernate + MySQL + Tomcat + Ant + Log4j + SVN; is this possible all together?
Hello, I am learning GWT for a while. I tried tutorials of GWT. I learnt Hibernate as well. Now I am going to work on a real application. It is divided into 2 parts: Standalone Desktop mode(without internet connection) and web mode(with internet connection, front end will remain same as for Desktop mode, with an added button nd some message boxes). This project is connected to other project so i have to use the same configuration (if possible to use this all) used for that main project, the configuration includes: GWT - for front end and business logic Hibernate - Database connectivity MySQL - as a database Ant - war built tool Tomcat - Application server log4j - for logging SVN - repository My query is ' can I use this configuration for this project? Desktop mode has no Database connectivity, but use xml to store data. Do i need to use Tomcat for desktop mode?

Client side code breakpoints stop to work after user was redirected to the guice servlet page, and the back to the GWT page.
Hi, guys! I am using GWT 2.0.4, Ubuntu 10.04, JDK 1.6.0_20. I am trying to implement Google OAuth in my GWT application. And it needs to specify callback URL, which will be used to store authorization params after user has logged in. In my case this callback url is a guice servlet, which retrieves needed auth key and redirects user back to my GWT application. In other words the whole process in hosted mode goes like this: 1. User opens my GWT application (breakpoints in server and client code both are triggered) 2. User tries to log in using his Google account. Application redirects him to the google authorization page. 3. After user has logged guice servlet retrieves auth key (breakpoints also are triggered) 4. Guice servlet redirects authorized user back to GWT applications page, where he clicked "Login" Starting from this moment only SERVER side breakpoints are triggered. Client side breakpoints are still there, but nothing happens with them. In the last step I tried to redirect user to GWT page with gwt codesvr parameter specified (?gwt.codesvr=127.0.0.1:9997), but it creates one more connection in Development Mode tab in Eclipse, which is not I really wanted.

How to build a rules-based form controller for a dyn. form in GWT
Currently learning GWT, and I still cannot imagine how to build a
*rule-based* controller for a dynamically composed form -- preferably
a multipage one, and -- due to GWT concepts -- obviously running on
the client side in JavaScript.
The idea is to have a multi-sections/multi-tabs registration form
that:
(a) shows its questions according to "question specs" from a
backend database,
(b) gives the users instant input validation feedback via locally
centralized validation rules base,
(c) controls the "questionary behaviour" after some locally
centralized "fill out" rules, e.g.,
* "When user fills out InputField A, hide section/tab C".
* "When user checks CheckBox B, also check boxes Y
and Z automatically".
* "When user selects D,E and F then show {widget} G".
* ...
(d) finally submits all the collected data (from each form page/tab)
to a server-side service (i.e. 'submit' button triggers RPC).
The main point is to optimally have all the validation, filter,
action/
behaviour, etc. rules centralized at one place -- hence the rule-based
approach.
The main issues are:
1. Which way to go for realizing such a "JavaScript Rule Engine"
solution in GWT?
2. Does there already exist a GWT framework or Composite targeting
*rule-based* form controllers for the client side?
Hope some more experienced GWT programmers can help me further on
this topic.
Kindly regards,
Alessandro

Re: Firing native events in GWT?!
Hi, first tnx for the rpl.. yes thats ok...also would be ok to fire onNativeEvent in widget method...but I have more components(widgets) related to that event..and i dont like to keep instance of all of them and fire the event one by one...for each... In gwt 1.6 there ware metods in Document.firexxxnativeEvent...but after 2.0 there not inside...and i dont no how can be done...

Re: Problem with UTF-8
Hi,
Have you specified the UTF-8 before creating file or just change it
while your files were created ?
I've just copy paste your Label in a project where .java file are
UTF-8 encoded and everything works fine.
Just check on one of your file the properties that is attributed to it
(contextual menu on one of the incriminated java file): here you must
have UTF-8.
