Hi all,

I am working on a rather large ecommerce application, and we recently noticed that many of our HTML elements are being given YUI generated ID's.

Something like: <div id="yui_3_4_5_67893243"></div>

This appears to be happening indiscriminately, and since it is not a trivial process, we would love to find the source of the problem in our code, or in YUI's. Any thoughts on why/when YUI would do this ID generation? And how it could be running a bit rampant?

Thanks!

It's not only about optimization by caching. It is an important part of the Event system and the Widget infrastructure. For instance, there is a function called Widget.getByNode() that uses that id to match DOM nodes to widgets. That allows for event propagation in widgets and other cool stuff.
