问题 I'm trying to use Selenium WebDriver to input text to a GWT input element that has default text, "Enter User ID".

问题 We define all our internationalized constant strings in a single properties file LocalizableResource_xx.properties (one per language) located in google.gwt.i18n.client . This way it is possible to access the constants in Java code via the constants interface Window.alert(myConstants.helloWorld()); as well as to use them inside the UiBinder .ui.xml <ui:attribute key="some.key" name="text" description="useful info" /> This approach doesn't work well if the string contains a single quote ( ' ).

问题 In the gwt-user.jar there are 2 EventBus interfaces and SimpleEventBus implmentations. com.google.gwt.event.shared.EventBus and com.google.web.bindery.event.shared.EventBus I'll refer to these as 'gwt.event' and 'web.bindery'. Looking at the JavaDocs and source code I can see that the gwt.event merely wraps the web.bindery one. However the gwt.event implementation also hides a number of deprecated methods So which implementation should I use? (I'm on GWT 2.4) 回答1: Generally you should use the

问题 Is there a documentation of gwt.xml, a list of the setting with all accepted values? In my case i turned css obfuscation off in debug/developer environment.

The same i want with "CssResource.style". the only thing i found so far was the value "obf" but it seems that value also produces "human readable classes" see here for

问题 I'm trying to get some automated UI testing going on a GWT application and I'm having trouble finding a way to track UI elements. For example, I have the following: <g:Button text="Submit" ui:field="submitButton" enabled="true" /> which generates: <button class="gwt-Button" type="button">Submit</button> Its a compiler error to set both ui:field and id (id is considered deprecated anyway) so the problem is that I have no easy way to select my submit button using something like selenium.

问题 There are several questions on StackOverflow discussing the question of when one should use an assert statement versus throwing some exception. (Examples here, here, here, here, and here. However, I have come to suspect that the conventional wisdom of assert-versus-throw is based upon the assumption that you are running within a JVM. In the GWT universe, where your Java gets transliterated to JavaScript and runs in the context of a browser, the set of tradeoffs feels different: asserts are
