String getUniqueId()
The value returned by this method should always be unique within the context of the rendered page, and therefore reliable for referring to the represented user interface element using a DOM selector within a front-end script.
This value must be usable in an XML document as an ID attribute without modification. Therefore, only letters, numbers, hyphens, and the underscore character are permitted.
