Not a "global" location, but you can set it up once for each GWT.create() of a given service:
1. cast the service to a ServiceDefTarget<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/ServiceDefTarget.html> 2. call setRpcRequestBuilder<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/ServiceDefTarget.html#setRpcRequestBuilder(com.google.gwt.user.client.rpc.RpcRequestBuilder)>with a custom class extending RpcRequestBuilder<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/RpcRequestBuilder.html> 3. that class would either: - create a custom RequestBuilder, overriding the send() to show the message and wrap the callback to hide it on success or failure - show the loading message in onFinish() and wrap the callback to hide it on success or failure -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
