Notes on application states

When changing color on an HTML button, here is the stack trace upon entering davinci.ve._Widget.js:setStyleValues():

declare.setStyleValues (_Widget.js:559)

And here is the current code for setStyleValues():

	setStyleValues: function( values) {
		if(!values) {
			return;
		}
		var styleDomNode = this.getStyleNode();
		var v = this._sortStyleValues(values);
		var text = this._styleText(v);
		/* reset the style attribute */
		dojo.attr(styleDomNode, "style", text);
		if (this.dijitWidget)
			this.dijitWidget.style = text;
		if (text.length>0)
			this._srcElement.addAttribute("style",text);
		else
			this._srcElement.removeAttribute("style");
	},
