Re: GWT Code splitting issue

Embrace asynchrony!

Because you can't "wait" for the code to be downloaded and run, make you create() method asynchronous.

Another option in similar cases is to use an AsyncProxy but it won't work well with your ClientBundle scenario: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/AsyncProxy.html

Hi all,

I have recently used code splitting to reduce the initial download file size of my application. Here is my scenario. I have split the code in below method .

public <T extends ClientBundle> T create( int themeId )
    {

        switch ( themeId )
        {
            case THEME_1:

                GWT.runAsync( new RunAsyncCallback()// code split
                {
                    @Override
                    public void onFailure( Throwable reason )
                    {
                        Window.alert( "<< Code Split : Code download failed [ThemeImpl.java::create] >>" );
                    }

                    @Override
                    public void onSuccess()
                    {
                        resource = GWT.create( WidgetResourceThemeWhite.class );
                    }
                } );

                break;
          
        }

        return ( T ) resource;
    }

Im creating a instance of resource inside onSuccess() of case statement. but before it gets initialize the method return the value of resource. I want to return the value of resource only after its initialized. How can this be done ? Thanks in advance.
