would that number be unique per page, container or component?
Per page. The count is unique per rendered page.
In order to be w3c compliant they'd need to page unique, correct? I guess a disadvantage would be that you can hardly change your design (you'll change the numbers) without having to (manually) change you CSS / JS selectors. Which obviuosly is true for the original naming algorithme as well.
This is an error in the design already. When you use the wicket component ID's for selecting a component which can be used multiple times in your page, you are already in trouble: the components ID is not unique. In CSS you are misusing the ID as a class identifier, and I don't know what the consequences are in Javascript, but I figure they aren't good.
ID generation is something Wicket should do, and not leave it to the developer of the applications. Like I already stated in a previous message, when you are a component developer, you can't possibly foresee what kind of usage your components will have. So as a component developer you can't generate ID's according to your own rules. Wicket generates the final page and composes it from its added components, so Wicket has the information to make the IDs unique for each page. Nobody else has this knowledge: - not the developer who created the page, as he/she has no control over the components which are developed by other developers (our licensing doesn't prohibit commercial, closed source components!)
- not the developer who creates the supplemental components (the date picker for example), as he can't control what naming schema his components will recieve.
