XPages Custom Control - getComponent/hash of all clientIds from the browser

Until IBM implements getComponent in the browser, I've made a litte experimental custom component that lets you do something similar to getComponent in server side scripting. So far it only works with unique components (doesn't work with repeated items).

The component adds a script-tag at the bottom of the page, using the output stream that you get from facesContext.

The API is small:
Application.renderedIds
An object containing { designerId: clientId(s) } for all (?) components in the XPage. If there are multiple versions with the same designer id, you'll get the wrong id. (see comments)

Application.getComponent( designerId )
Similar to the getComponent in Server side JS. Fetches the rendered id from Application.renderedIds, then uses the corresponding clientId in a document.getElementById-statement. This method will fail if you try to multiple controls that has the same designerId (repeated items for instance).



Comments/bugreports/wishes are appreciated (but I can't promise anything).

I'm probably going to start working on a big XPage application along with some colleagues in the near future, so it's not impossible that I might turn this into a client side utility component. Time will tell.
