jQuery UI costed a day of my life

Last week I lost a whole day together with a colleague investigating why our jQuery UI Tooltip widget didn’t want to work. Here is the original code:

	<span id="test">show tooltip</span>

	$(function () {
	$("#test").tooltip({content:'hello tooltip!'});
	});

After a long search and a lot of head scratching we finally discovered the cause; the jQuery UI tooltip only works when you specify a title on the tooltip you want to use(even when you want to specify your own content.

<span id="test" title="this title is required to make the jQuery UI tooltip work">show tooltip</span>

	});
