Is it possible to place the busy icon (like the one used in the Status widget) in the mask message? I'm not clear on how to do that with 3.0. I was able to do it in previous versions using code similar to this
Code:
String url = GWT.getModuleBaseURL() + "gxt-resources/images/default/grid/grid-loading.gif";
AbstractImagePrototype image = IconHelper.createPath(url);
panel.mask(image.getHTML() + msg, "tree-mask-msg");
But when I try to do the same thing, the actual URL shows up in the message rather than the image.

Thanks!
