Blink body of an Ext.form.Panel

To draw attention to a form of creation, I wanted to give a small effect on my form body using the 'highlight' function on an HTML DOM object. Here is the ExtJS code I used:

var myForm = Ext.create("Ext.form.Panel");
...
myForm.body.el.highlight("0000DD", {
  attr: "backgroundColor", //can be any valid CSS property (attribute) that supports a color value
  endColor: "ffffff",
  easing: 'easeIn',
  duration: 500
});
