Test JSF using selenium, element not found

Hello,

Anyone use Selenium IDE to test JSF app.

Downloaded the latest selenium 2.5. Trying to test JSF web app using
selenium: record and play. recording: no problem. But playback, input
element not found error. The input text field id is foo:bar:inputText. In
the Selenium IDE, the find command can find the element, but playback
complains the element not found.

Does Selenium support JSF? JSF element id is like aaa:bbb:ccc:ddd? Thanks.
