Re: how to cancel a scheduled command?
Here is the answer:
The execute() method of Scheduler.RepeatingCommand returns a boolean.
If true, then the command will be invoked again. If false, it will be
cancelled.
public interface RepeatingCommand {
/**
* Returns true if the RepeatingCommand should be invoked again.
*/
boolean execute();
}

Share a client-side singleton across modules?
I would like to share a client singleton across GWT modules. Is this possible? If so, how? I have several modules that need to share an EventBus (SimpleEventBus) instance. Creating a singleton in GWT Java code and having all modules inherit from the common module did not work. Each of the root modules has a different instance of the EventBus. I also tried using the replace-with and create() approach documented in ClientFactory of GWT MVC and that did not work. Each module had it's own instance. Ideas?

Re: StackPanel child not rendering in IE7 quirks
The problem only occurs when a DockLayoutPanel is within the StackPanel. Does anyone know of issues with mixing StackPanel and DockLayoutPanel?

StackPanel child not rendering in IE7 quirks
Has anyone ever seen something like this before: I have a StackPanel in my application. On IE7 only, The first time I start my application in Tomcat, and navigate to the application in the browser, then the contents of the first stack panel renders correctly. If I hit refresh then the panel is invisible. The stack is visible, just the panel contents are hidden. Any subsequent refresh results in same. If I resize the window, then the panel renders just fine with no further problems for the live of the app. If I switch stacks and come back then the panel renders just fine with no further problems. This does not happen in IE6, IE8, any FF, Chrome, or Safari. Any ideas? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Class loaded incorrectly in GwtTestCase: NoSuchMethodError
Alright, I figured this out. Ignat was correct after all... there was an old version of my class in the classpath.

Re: Class loaded incorrectly in GwtTestCase: NoSuchMethodError
Thanks for the info Ignat. Unfortunately, this is not what is happening. The class is a class I wrote. There is no other version around. Plus, the class as loaded does not have the /wrong/ methods and fields on it, it has /no/ methods and fields on it. Anyone else have ideas?

Class loaded incorrectly in GwtTestCase: NoSuchMethodError
I am receiving a NoSuchMethodError for one of my object's constructors. It only happens in a GWTTestCase. The object in question is called "MyClass" in package "com.example" The MyClass object does load, but the Class instance has no methods, no fields, and no constructors on it. There are other classes in that same package that load correctly. When I run within Tomcat the class loads correctly and is usable. When I run in GWT Hosted Mode the class loads correctly and is usable. When I run within the GwtTestCase the Class instance is missing all its fields, methods, and ctors. There is really nothing special about MyClass. The test case just uses GWT.create() to instantiate the remote service and then invokes a simple method on it. This is GWT 2.0.3 on 64 bit Ubuntu linux running in IntelliJ IDEA. Any ideas about what could be wrong? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

notification of server side shutdown within Servlet
I need to be notified when the server side of my GWT application is shutting down . Specifically, one of my RemoteServiceServlet subclasses is initializing a resource that must be properly released when the system shuts down (an ehcache cache to be exact). In other frameworks I have used, I was given a method to override or listener to implement that would call me back when the container was shutting down my app. Is anything like this available in GWT? Or should I try to wire in a Tomcat shutdown listener of some sort?

Re: DevMode 64-bit Linux InteliiJ IDEA
