gwt-maven-plugin fails with NullPointerException
Caused by: java.lang.NullPointerException at org.codehaus.mojo.gwt.ClasspathBuilder.buildClasspathList(ClasspathBuilder.java:71) That line would mean that the logger hasn't been initialized. Which Maven version are you using? The plugin has been built and validated with Maven 3.2 (and was developed with 3.0), and I just tried with Maven 3.3 and integration tests pass too; but...
Adding same widget to two panel causing issue
Your panel subVP isn't added to anything, and when the box is added to subVP, it is removed from mainVP. Widgets can only be one place at a time. -- (adding more detail for the comment posted) This is part of the basic assumption of how a widget works -...
GWT - Could not get type signature for class
I have tried changing the type declaration, adding Serialization, switching to IsSerializible, and nothing works! You missed one: you must have a default (zero-arg) constructor, or a new instance can't be created. The deserialization process creates an object then assigns the fields. I believe you can make this constructor...
How to migrate a a custom sublass of GWT DevMode to GWT 2.7.0 Super dev mode
gwt,google-plugin-eclipse,gwt-super-dev-mode,gwt-2.7
I didn't find any documentation but I succeeded to get started. Here are the things that I had to do: I actually didn't have to change my launcher/dev mode code at all. Eclipse *.launch file had to be modified to add -nosuperDevMode argument. I could not get the super dev...
window.getSelection() Does Not Work When Run Via JSNI and On IE

GWT elements are not visible
It looks like a problem with missing styles - please double check that gxt-all.css is available from where you reference it in your host page. Use your browser's developer tools to see if it's not throwing a 404. It seems that the missing resources are mentioned in Step 1 in...
Grid with rows in anchor not visible in GWT (UIBinder)
You create your ticketTable and your links with UiBinder (createAndBindUi) and then you create a new Grid (re-assigning the ticketTable field BTW) and move your links to it (setWidget), but you never actually use that Grid anywhere. So, basically, you've moved your links to somewhere that's never displayed, so they...
Specify Library Target of Maven
It looks like you're trying to bend Maven to do things differently than what it expects you to do (e.g. here use war both as input and output folder). As a rule of thumb, never try to fight with Maven, you'll lose eventually. Follow the (almost-undocumented) Maven Way™ or just...
How should I set a custom style on a object that is a gwt component?
java,html,css,gwt,web-development-server
There are two ways to do that. First, you can define the rule in CSS. You do need to learn HTML and CSS for web development - no way around that. Second, you can set a particular CSS property directly in your code: loader.getElement().getStyle().setFontSize(24, Unit.PX); ...
How to update Eclipse GWT Plugin 2.6.0 to higher version
You need to download and unzip the SDK manually, then tell Eclipse where to find it: https://developers.google.com/eclipse/docs/using_sdks#adding-sdks …but GWT Designer is deprecated and won't work with newer versions of GWT. 2.6.1 is the last that works....

Set focus to an Input in a gwtbootstrap3 Modal
gwt,twitter-bootstrap-3,gwtbootstrap3
You should be listening on the ModalShownEvent (note: Shown, not Show). ModalShowEvent is fired when the modal is requested (for example, programmatically) to be shown. ModalShownEvent is fired when the modal is actually shown. This somewhat confusing naming is based on the events of the native Bootstrap Modal's events: show.bs.modal...

How to detect or check whether a Poly Line was Inside Another Poly Line or Overlap with Other Poly Line Using Google Maps
javascript,google-maps,gwt,google-maps-api-3
You could use geometry library isLocationOnEdge(point:LatLng, poly:Polygon|Polyline, tolerance?:number) To determine whether a point falls on or near a polyline, or on or near the edge of a polygon, pass the point, the polyline/polygon, and optionally a tolerance value in degrees to google.maps.geometry.poly.isLocationOnEdge(). The function returns true if the distance between...

How to update gwt-maven-plugin Archetype?
java,eclipse,maven,gwt,maven-archetype
It looks like the archetype catalog is out of date in your Eclipse. I don't know how to update it (I don't even know how Maven does it outside of Eclipse), but an easy workaround is to use the Add Archetype… button to add org.codehaus.mojo:gwt-maven-plugin:2.7.0. That being said, despite the...
How to group fields to get one change value handler
I think you can achieve more or less the same behavior by registering the same handler on both filterItemName and filterItemAmount : ChangeHandler handler = new ChangeHandler() {...} this.display.getFilterItemAmount().addChangeHandler(handler); this.display.getFilterItemName().addChangeHandler(handler); ...
Set log4j.properties for GWT
GWT doesn't create anything in WEB-INF/classes; it only generates JavaScript (and possibly CSS, PNG, etc.) files in a subfolder (named after your compiled module) of the output directory (generally where the WEB-INF/classes also is, but that's just because several things are configured with the same output directory). The log4j.properties you...
Shrink browser content to browser window size
Without specific code examples a specific answer is difficult to give. But to react to browser resize you need to implement the onResize() method. The layout panels you name call this method on children that implement the interface RequireResize. So the panel with the chart should implement the onResize(), and...
GWT Eclipse: using classes from other projects cause "Server class … could not be found in the web app, but was found on the system classpath
The details depend on your build tool and/or IDE, but the goal is to have all server-side classes in the webapp's WEB-INF (either in WEB-INF/classes, which is probably the case for your GWT project, or in a JAR in WEB-INF/lib). This will be necessary anyway when deploying the webapp to...
Why Intellij deletes obsolete files when trying to run DevMode?
After sending a request to Intellij support team, they gave me the following answer: Adding the following two lines to the IDEA_HOME/bin/idea.properties file: idea.gwt.clear.unit.cache.before.run=false idea.gwt.clean.files.created.by.dev.mode=false Which makes sense, because the only thing I need is to prevent Intellij from deleting my local cached files.

Is it possible to shadow Vaadin Applicaitons
well, although it could be possible to have this feature in Vaadin, it is not implemented right now, nor planed. Vaadin RPC mechanism maintains synchronised set of states between the user session in server side and javascript in client side. In theory it could be possible to code some kind...
“Development mode is loading…” and “Waiting for launch URLs” in GWT
java,gwt,google-plugin-eclipse
Both errors (missing gwt-codeserver, and unknown argument) hint that the Google Plugin for Eclipse didn't properly detect the version of the GWT SDK you're using. GWT 2.3 is now really old, so I'd suggest trying with GWT 2.7. As you're beginning with GWT, it's also better to start right with...
GXT MessageBox with scrollable content
It turns out that I was quite near to a solution : the idea is to let the MessageBox adapt its size to the content, and then to fix the size of the ScrollPanel like this : HTML content = new HTML(StacktraceTemplate.RENDERER.render(stackTrace)); ScrollPanel container = new ScrollPanel(content); container.setHeight("700px"); HTMLPanel panel...
ActivityMapper, dealing with regions which don't change a lot
gwt,activity-manager,gwt-activities
When an ActivityMapper returns the exact same Activity instance (reference equality, i.e. ==, not equals()) as previously, then the activity is not restarted, and the region is not touched. This is a deliberate optimization for those cases of regions that don't change often (e.g. headers or menus, or a master...
Filtering for UI developed using GWT
We have a GWT app that supports sorting and paging of large tables. Both is done in the backend. First, I'd say it depends on how fast your backend can handle these requests. If it's about 20ms or less per roundtrip you could do it in the backend. Another point...

Polymer core-drawer-panel throws exception at loading

GWT-Polymer uses a new feature in GWT called JsInterop, so I think the error you are getting is because you are not using the compiler flag to enable it. Try to add to your compiler the option: -XjsInteropMode JS BTW, gwt-polymer is using gwt-2.8.0-SNAPSHOT which have last features, so probably...
java.lang.NoSuchMethodError: com.google.gwt.util.tools.Utility.versionCompare - Google Web Toolkit SDK 2.6.0
If this is a Maven project, then M2Eclipse and the Google Plugin for Eclipse should auto-configure the project to use the GWT referenced from your POM, and not the one you could have installed in your Eclipse. So the problem is that you have GWT 2.6 on the classpath; your...
Can't add selectonHandler to TabPanel in Gwt
The SelectionHandler needs to be of type Integer, not Widget (see here). It should look like this: TabPanel panel = ...; panel.addSelectionHandler(new SelectionHandler<Integer>() { @Override public void onSelection(SelectionEvent<Integer> event) { } }); or TabPanel panel = ...; SelectionHandler<Integer> handler = new SelectionHandler<Integer>() { @Override public void onSelection(SelectionEvent<Integer> event) { }...
Not possible to trigger GWT listbox ChangeHandler using CasperJS

Is it possible to use widgets in a GWT ToggleButton?
ToggleButton's g:downFace takes an ImageResource as an image= attribute: – Source: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/CustomButton.html But you cannot use both an image and text that way. AFAICT, you can however use an image and text through HTML (but without widget): <g:downFace>downFace Text <img src="{res.wantedImage.getSafeUri}" /></g:downFace> or through a @sprite in a CssResource: <g:downFace>downFace...
GWT i18n changing locale
The default value for the locale.searchorder configuration property is queryparam,cookie,meta,useragent, so a query-string parameter will override the user-agent's locale (i.e. what you, and most people, would expect).
Smart gwt grid grouping doesn't work when records are over 1000

Ok thank you very much for your comment. Indeed, my problem concerned the *.nocache.js and *.devmode.js files. I started my project (my first one in GWT) in 2.6 version and these files were created (by dev and super-dev-mode) and versionned by my fault. So, when my jenkins deployed my project,...
How to transform elements to widgets?
try with something like FlowPanel panel = new FlowPanel(); HTML wrap = new HTML().wrap(myElement); panel.add(wrap); RootPanel.get().add(panel); note : the FlowPanel is not strictly necessary.

Lazy Loading on a List of Objects using Java?
You don't need a plugin or a component. You simply attach an event handler to a widget that triggers additional loading requests. It can be a ScrollPanel if you lazy load on scroll down, or a Button/Label (e.g. "Show more"), etc. When this event is triggered, you load and display...

GWT 2.7's Super Dev Mode (and from the _g$ in your class literal field, I think that is what you are using) has been observed having other issues like this, but when compiled the issues go away. If this is indeed what you are seeing, the issue seems to be...
What Cell,Table can I use to create a grid of only images in every cell, in GWT?
css,gwt,web-applications,grid,cell
You can use a simple FlowPanel as a container, and add each image with a float set to "left". Alternatively, you can use a flex-box model with flex-flow: row wrap on a container. You don't need any widgets for this. This is simple CSS, and it will give you the...
How to configure mvn/Jrebel/wtp/gwt/eclipse to work smoothly with changes on the service interface
The client side doesn't need anything special. The server side though requires the RequestFactory and all its RequestContext and proxies hierarchy to be processed by the validation tool. From the command line, in the context of the archetypes, that means launching the process-classes phase on the *-server module, e.g. mvn...
Getting Exception in thread “main” java.lang.VerifyError: class com.google.gwt.dev.HostedModeBase$ArgHandlerNoServerFlag
gwt-dev-windows.jar is an old dependency from pre-2.0 GWT (you should have already removed it when updating to 2.0 a while ago), and it conflicts here with the newer gwt-dev-2.7.0.jar.

GWT 2.7 Super Dev Mode not working while testing on the same network
As Thomas pointed out, the problem I had was that from GWT 2.6 onwards, if you want to test from other devices in the same network, you have to whitelist the addresses you'll be using in each *.gwt.xml file using a command line like this: <set-configuration-property name="devModeUrlWhitelistRegexp" value="http://(localhost|127\.0\.0\.1|192\.168\.150\.(\d{1,3}))(:\d+)?/?.*" /> I...

GwtMockito - click handlers for many buttons

How do I handle the event from the TextBox clear icon in GWT?
The click on the X triggers a 'input' event. So one way to catch it is to sink the input event to the textbox and overwrite the onBrowserEvent.

How to append a link to gwtbootstrap 3 InputField
The HasText bit is about InputGroupAddon, not Anchor. "Text-only context" (implied by implementing HasText) means you can only put, well, text into that widget. Either through the text property (<b:InputGroupAddon text='Name' />) or inside the tags (<b:InputGroupAddon>Name</b:InputGroupAddon>) - those declarations are equivalent. You can't put unescaped HTML or widgets in...

I'll assume that you've got the code generation side covered, and only focus on how we might pick the correct implementation in GWT: but you'd still have to somehow feed the factory with the current context, e.g. the current locale). We could do this at runtime, as you suggest, but...
