Hello Sarwar, thank you for your response. I've considered using selectors, however that alters the URL for the page, which is undesirable.
The other approach, using if-else statements in the JSP is something I have prototyped using a taglib, which works fine, but it requires that each JSP has to be wrapped into the tag. Ideally, i could handle this completely transparently. The key idea is to keep the actual JSPs clear of the actual switching behaviour. After all, the same behaviour will be used in many different JSPs, and I don't like the idea of having to rely on developers manually cutting and pasting code between JSPs. I was wondering how Sling selects which script actually to render. >From my understanding that happens when Sling evaluates the sling:resourceType field. Is there a way to hook up to that decision process?
