I agree with Chad, I have this in my click handler:
display.getButton().addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
display.getButton().disable();
display.setStatusText("Please wait while your connection is
verified...");
doAuthorize(); //rpc called in this method, and status
updated with pass/fail messages, button re-enabled
}
});
