compilation-mappings.txt
Hi. In my project, GWT outputs a compilation-mappings.txt and modulename.devmode.js files. I think they shouldn't be needed in production, is there a way to configure (e.g. compiler flag) so that those files aren't generated?

JSONPath
Hello. Does anyone know a GWT library that supports JSONPath queries at runtime? I don't know the desired JSONPath expression at compile time (it's a configuration kept on the server), so i think any solution relying on GWT generators doesn't fit my use case.

JSInterop and terse JSNI syntax

Handling mouse events in capture phase
Hi.
Is there a GWT API to add an event handler to a widget in the capture
phase?
The equivalent to the following javascript:
target.addEventListener('touchstart', handler, true);
I know of Event.addNativePreviewHandler() but do not think that it fits
easily to my use case (without handle every single event in the application)
** I want to catch mouse events on a parent widget and avoid to target
child ones and still be able to normally handle mouse events on other
widgets in the screen.*
Best regards,
Nuno Rosa

Re: My CellTable is slow and I don't know why
It runs the DevMode main class, ture. But I am quite certain mvn gwt:run is fueling me the compiled javascript. The project compilation time is huge for making the gecko_1_3 and safari permutations (since I am testing in both chrome and firefox). What would be the point of compiling all that java into javascript if the gwt:run would later not use the compiled javascript. Moreover, if in the module user.agent property I take away the compilation for gecko, when I load the page with firefox I get alarms that there is no compiled javascript for my user agent. What i am going to check out first is weather or not the dead weight of the cell table is not related to the DOM structure of my GWT components tree. Such as, for example, laying the table within the bootstrap grid model. Potentially, each of these nested page components that are being used for layout or whatever else, are all like the cell table implementation crowing up the application with mouseover, mouseout events. You put the mouse on top of a cell table row, and there goes a mouse over buble up to kingdom come. I am considering that It is possible that this drag on performance has to do with a by default spamming of dom events. Events running from the bottom of the DOM tree up to the very top element, all bubbling and lagging up. So what I am going to try out this time, is to dump the cell table outside the overall page layout, so that there aren't any OnWhatever events to buble up to. Let's see if that is is the problem. And if that is indeed the problem, Christ!, you do have to be ever careful with most of the gwt components you use cause they just booby trap the html elements with events you did not even know where being played out for you.

Re: My CellTable is slow and I don't know why
Christ!
I have never seen a hover effect so sluggish (probably because the
hover/graying effect is being added programatically by CellTable
implementation code of the mouse out and mouseover).
The online sample goes fast on the browser,
http://www.gwtproject.org/doc/latest/DevGuideUiCellTable.html
The one triggered by mvn gwt:run is a disaster.
Mouseout: 176 ms, mouseover 208 ms, according to speed tracer, but it looks
even slower.
I am basically using the standard css from GWT along with the css from
twitter bootstrap.
I tried both the CellTable from bootstrap and from GWT both are just dead
slow.
Firefox is considerably faster, but even there you feel the delay for the
hover effect to show.
The table has the three rows of the example!
At this rate I will just have to extend the cell table and override the
mouse out and mouseover events to simply do nothing.
I tried removing the bootstrap CSS, which I want to keep, but it also
seemed to have no effect on the performance.

Have you tried looking at it with SpeedTracer? We tested with large
tables
(100 rows), and the hover code is pretty straight forward.
In past applications, we've seen performance problems when hovering
due
to descendant style selectors because of the way they are
implemented in
browser.
For example, you have this CSS style defined:
.myRandomWidget td {
padding: 3px;
}
And you have a CellTable that is NOT myRandomWidget, then changing
the hover
style of the row will cause some browsers to walk up from every TD
in the
CellTable trying to match the style definition. In the degenerate
case,
where CellTable is not myRandomWidget, this means walking up to the
body
element. This is a native browser implementation, and the only
solution is
to avoid descendant style selectors.
If this isn't the case, SpeedTracer should be able to help you
narrow down
the performance problem.

Core Script Injector (faster than its shadow?)
Hi,
In an application that uses Highchats and Bootstrap, the
com.google.gwt.core.client.ScriptInjector does not seem to be working
correctly for me.
Basically, during the onLoad() of my entrypoint, if I try to inject js
Highcharts.js dependency using the core gwt injector, I end up not
seing absolutely nothing injected into the Head of the html.
Though i can see that the Inject Method is tring to put the javascript
string into the Head... it just does not seem to be there when the module
loads.
This does not work:
public static void injectHighchartsJavascriptIntoHtmlHead(){
TextResource textResource = HIGHCHARTS_JS_RESOURCE.highchartsJs();
if(!highchartsJsResourceInjected){
com.google.gwt.core.client.ScriptInjector.fromString(textResource.getText()).inject();
highchartsJsResourceInjected = true;
}
}
when the From String completes, automatically the following javascript
error takes place in the browser:
1. Uncaught TypeError: undefined is not a function
hosted.html:30http://127.0.0.1:/gwtexpenses/hosted.html?gwtexpenses
1. (anonymous
function)hosted.html:30http://127.0.0.1:/gwtexpenses/hosted.html?gwtexpenses

4.
__gwt_jsInvokehosted.html:76http://127.0.0.1:/gwtexpenses/hosted.html?gwtexpenses
5. gwtOnLoad
On the other hand, if I modify my onLoad to instead of calling the Resource
inject function, I use the non core Bootstrap resource injector:
String javascriptToInject =
org.moxieapps.gwt.highcharts.client.resources.Resources.getHighchartsJs().getText();
com.github.gwtbootstrap.client.ui.resources.JavaScriptInjector.inject(javascriptToInject);
Well, then I have no problems.
One thing is clear, both mechanisms of populating the head element are
nothing alike. The core core seems optimized to use native functions,
The bootstrap Script Injector, on the other hand, gets the Header Drom and
populates using gwt Dom wrappers. In this case, you actually see the point
in time where your javascript gets injected and that required dependencies,
e.g. jQuery have also been dumped into the header.
Thanks in advance for any input!

curious class class not found exception
Presently, when i try to run my gwt application through eclipse I am
getting a curious:
java.lang.NoClassDefFoundError:
com/google/gwt/user/client/rpc/RemoteService
The intersting about this exception is that by command line firing a
gwt:run my project loads and runs just fine.
It is thorugh eclipse, where the classpath is even larger, that the
exception happens.
After creating a fancy perl script to farm the .jar files and directories
indicated by oracle visual vm for sun.java.classpath system variable, i was
able to track that my maven runtime project has this class under the
following loacations:

]
};
On the other hand, when I use the google eclipse plugin to lunch the
com.google.gwt.dev.DevMode , I have an even larger set of jar files
containing this class (due to overhead jars that originate from automatic
project configuration triggered by the eclipse plugin):

Re: GWT ui:style how big of a bad idea (or not) is it to use it?
Thank you all for your replies, And In general I tend to agree that you should not promote tight coupling between your app functionality and the presentation styles. On the other hand, Ryan Shillington, JQuery is javascript, but as you know most Great Jscript libraries jave wrappers for GWT. That is the case with jquery, http://code.google.com/p/gwt-jquery/. So yes, you can use JQuery from withing GWT. Another thing is, say, for example that in page that you are rendered you have a list of row and each of these rows has a cless ODD or EVEN. Say that you want to hide away all ODD rows. Why would it be best to have your GWT code traverse every single row in the set an based on your index % 2 decide weather or not collapse it, than have a CSS selector in gwt-jquery kill away all ODD rows? Much less code! I would normally live very well wich such a depencency, provided that if would be making my code use a CSS resource getter to find out the ODD classname. My kindest regards, Nuno. On Saturday, August 4, 2012 11:33:09 PM UTC+2, Joseph Lust wrote: To start with CSSResource is awesome and I highly recommend using it. It forces you to program *better*. Should you really be trying to pull elements out of the page depending on their CSS names? Seems like a bad day if you ever want to rebrand or dress up your UI. If CSS is the graphical dressing of the site, separate those concerns from the functional aspects. Further, using those CSSResource interfaces keeps you from ever using string literals in your Java code or UiBinders, which is a best practice. Additionally, with UI Automation tests our testers are tempted to use ugly selectors based on class names. This is a poor idea because then a class name changes a year later and 400 tests fail, even though functionally the site works just as well as before. The real question here is what you want to do with your CSS. If you want to apply rules the site over, then don't use ui:style, but rather a CSSResource interface. This way that interface can be used by many widgets' UiBinders. However bespoke, small CSS tweaks do fit nicely into ui:style and you can always move them out to a CSSResource interface in the future if you want to use them multiple places. Note, from my experience you cannot well handle CSS inheritance/overriding between widgets with ui:style, but you can with standalone CSSResource interfaces.

GWT ui:style how big of a bad idea (or not) is it to use it?
Hi,
I am wondering how big a mistake is it to take advantage of the ui:style
feature in ui binder interfaces?
Say your styles are all comprised within ui:style tags, and you always
refer to them using the {style.} notation.
Now, on the browser, this shall all become obfuscated after
gwt:compilation, the style name are not recognizable.
If we were to follow this approach for every style used on the application,
wouldn't we also lose the potential of navigating the page dom with css
selectors for example using library such as the Jquery gwt wrapper?
What's the policy here?
One should never depend on the defined style names for executing, say,
presentation logic such as collapsing dom elements?

Re: GWT Designer Issues
1. Has suggested, opened an issue describing the problem (sample
project attached).
http://code.google.com/p/google-web-toolkit/issues/detail?id=6693
2. I assumed GWT Designer would setup a Dev Mode environment, i.e.

I will look into *.wbp-component.xml files and see if i can figure it
out.

So, you should help it, by writing script to create instance.

GWT Designer Issues
Hi, i'm having some issues with GWT Designer. [last beta] http://code.google.com/intl/pt-PT/webtoolkit/tools/download-gwtdesigner-beta.html 1.

{HEX}.cache.html leakage
Hi all, I've seen this a problem (or best practice) that should be
addressed which relates with OWASP's GWT presentation where they sate
that:
Are the {HEX}.cache.html files accessible by unauthenticated users?
Is the login functionality implemented using GWT RPC?
If yes, the {HEX}.cache.html file will be leaking out information to
unauthenticated users!
How one should prevent the {HEX}.cache.html to be accessible by
unauthenticated users?

Hi Ed
at first thanks for your answer.
1) If yes: then you have your solution as you only have to set the CSS

it's the first thing i tried. But it didn't work at all. here is a listing
of the involved part in my css file:
*.rightPanelReservedZone {*
* **background-image: url(images/bgleer.jpg);*
* **background-repeat: no-repeat;*
* **background-attachment: fixed;*
* **font-family: Arial, Helvetica, sans-serif;*

* **font-style: normal;*
* **font-weight: normal;*
* **height: 90%;*
* **width: 85%;** *
*}*
and i then add a new style by calling:
*//rightPanel.addStyleName(rightPanelReservedZone);*
* **rightPanel.setStyleName(rightPanelReservedZone);*
*
*
Like you can see, i tried the both methods, but without success.
I thought it could be a problem with the image's path. But to my surprise,
i the image was found as i try the following *panel.add(new

Re: Client or server?
a class in the client sive can also be used in the server side...just make it implements Serializable and send it back to the server with the RPC services. Also note that as the classes in the client package are going to become javascript, they don't implement all of the JRE. That may be also a factor to know if you should put this on the client package.

The question relates where to put a certain class. Classes in the client package are translated into javascript. Classes in the server package are executed as java (I'm using App Engine too). Say I'm building an app with a little game. I can write the game class at client side so that that code can be run at the client, what seems to be correct here. At the end of the game, the game should be persisted into the datastore. So I make it persistence capable but than the class is needed at the server side. What should I do now? Put it at server side and use it at client side too? In that case, the class needs to be inherited in the .gwt.xml, no?

Re: Can I invoke RPC Methods from Java
Just to correct something...i dont know if you can call these rpc services from another java application, but GWT does not use JSON on their RPC calls. it is possible to work with json, but the default value are serialized objects. On Wed, Jul 29, 2009 at 12:11 PM, Trevis trevistho...@gmail.com wrote: I'm also pretty new to GWT and your scenario never occurred to me. Generally i think that it's probably not the greatest idea to try and call the GWT RPC's from a different front end and i've not come across anything that would give you a wsdl (or something like a wsdl) that you could use from non GWT java app. But, i cant think of any reason why you couldnt make it work. The RPC calls are just HTTP Post requests which receive a JSON response. Introducing JSON into a non web app seems like a red flag to me but if you really wanted to do it, you should be able to convert those into java objects. I *think* that a better solution might be to just rewrite a SOAP based webservice layer that uses the same code that the GWT services calls. That's not a great solution either since it introduces duplication but perhaps a better way to go would be to port the logic to a SOAP based webservice layer and then call the SOAP service from the GTW RPC server so that the logic only exists in one place.

Re: Using class on both client and server sides
Also, if you class is just a pojo you dont really need to create it in two places... the server code can access all of your client code. You just need to make the classes you want to transport from client to server or vice versa. In your example Contact may stay in the client package, and if you need to send a Contact object to the server, or make the server send it to you, just make this class Serializable.

Re: Creating Stand Alone Composite??
If you create a new project with a module, dont add any entrypoint to this module.Then create all the composites you want in this module. after you may create a jar file of this project (to use anywhere) or you can just import this project into yours (click properties - java build path - projects and add your project - if you have the jar file click on libraries and add the jar.) Then just go to your gwt.xml file and add a line like: inherits name=path.to.your.gwt.xml.File/ the File is the name of the gwt.xml file. example: if the path to gwt.xml file is: com.test.toolkit.Toolkit.gwt.xml put: = com.test.toolkit.Toolkit This way, you can create many modules in the toolkit project, and group the composites by functionality.

I want to create a widget that will be able to be used in any of my multiple GWT modules. Every example on the web that I can find defines the composite in the same module that displays the composite. I need to see an example of two modules, one defining the composite and one that consumes the composite. If anyone has an example or can point to a web article showing how, I'd GREATLY appreciate it.

Re: GWT client side annotations
For what i know GWT has no support for reflection... i think you may get the
class name from the getClass() method.

Hi to all, it's first time that i try to use annotation in client side gwt
application, i tried to compile that code:
@Target( { ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@interface MyAnn {
String value() default ;
}
@MyAnn(value=foo1)
class B {}
public class MyAnnotation {
public MyAnnotation() {}
public static final void foo() {
B b = new B();
MyAnn ann = b.getClass().getAnnotation(MyAnn.class);
GWT.log( + b.getClass().isAnnotationPresent(MyAnn.class), null);
}
}
but when the GWT compiler reach getAnnotation OR isAnnotationPresent say to
me an error like this:
[ERROR] Line 31: The method isAnnotationPresent(ClassMyAnn) is undefined
for the type Classcapture#1-of ? extends B
What's wrong with my code? thanks for any hint
