Justin, I total agree, however I didn't see a way to inject adaptables into the Sling Adapter Manager without knowing the exact class to be adapted ahead of time. I would imagine there would be a way to change this, but I can't see one which would not require changing the Sling Adapter Manager.
If we could add a hook where you could specify an AdapterFactory to handle requests for a subclass of a particular class, assuming the exact class is not matched then we should be able to support adapting to proxy instances without further code for implementers. At the moment, there is an abstract class included in the Sling Proxy project which will make it easier for implementers to implement an AdapterFactory for their interfaces. Thanks for the feedback and please let me know if I missed something, -Dan -----Original Message----- From: justinedel...@gmail.com [mailto:justinedel...@gmail.com] On Behalf Of Justin Edelson Sent: Friday, March 29, 2013 3:36 PM To: dev@sling.apache.org Subject: Re: Sling Dynamic Proxy Hi Dan, This looks very interesting, but I'm curious why this code: ISlingProxyService slingProxyService;**** {...}**** Page page = slingProxyService.getProxy(resource, Page.class); Is not just Page page = resource.adaptTo(Page.class); Regards, Justin On Fri, Mar 29, 2013 at 3:14 PM, Dan Klco <dan.k...@sixdimensions.com>wrote: > Hello Everyone,**** > > **** > > A colleague (Michael Kelleher) and I have built an extension we would > be interested in incorporating into Sling, as a contributed module. > **** > > **** > > A short synopsis of this is, it functions as a far simpler, read-only > ORM for Sling.
