Ok, this code works
if(DOM.isOrHasChild(RootPanel.getBodyElement(), DOM.getElementById("loading"))){
DOM.removeChild(RootPanel.getBodyElement(),
DOM.getElementById("loading"));
}
However, both DOM.isOrHasChild & DOM.removeChild were deprecated. Then, the
question is:
What are the undeprecated code that can do the same task as the bove code?
maybe use releaseCapture or something likes that?
