Re: RequestFactory .with() to access non-relation (primitive) properties?
I'm pretty sure by default you can't. If you feel the urge to fiddle you could do something in ServiceLayerDecorator.getProperty that picks up on some extra state with the request. I know the requirement you mean though. Some extra layer of fetch profile. Not sure it would be worth the extra complexity though. We do something similar though for security. We have @PreAuthorize on getters and setters and our ServiceLayerDecorator returns nulls when the user is not allowed to read that property and ignore any requests to write to those properties.

Re: RequestFactory .with() to access non-relation (primitive) properties?
Thanks for the reply. Yea :/, the work involved in fiddling with the service layer decorator and server-side RF at that level currently outweighs the benefit for my need which is what I was avoiding. I think if I fiddled at that level I might just end up making the .with() work with primitives also. It would be a nice to have as the property resolution already does this for the proxy, I can't see the extension of .with() to include this as being much more complex. And thanks, an annotation like PreAuthorize is something nice to keep in mind if you're going to go into the decorator. The other way I thought of doing it would be to have 2 different entity proxies for the same entity. That way you could keep and use 2 different property definitions/contracts for the same entity and use the most appropriate one. This would also keep the code cleaner and more cohesive as your functionality can be written around the appropriate contract, at least in my opinion.

Re: RequestFactory .with() to access non-relation (primitive) properties?
If you try the multiple Proxies approach could you report back to the group? Be interesting to hear if it works out nicely. Proxies being allowed to have their own inheritance tree etc seems powerful but I'm quite sure for good or evil. On Wednesday, July 24, 2013 12:20:11 PM UTC+1, GWTter wrote: Thanks for the reply.

Re: RequestFactory .with() to access non-relation (primitive) properties?
Will do. My approach would involve distinct proxies since I don't think RF allows for inheritance on EntityProxys even if they both have @proxyfor defined because it looks for the methods defined exactly on the proxy (it definitely won't currently let you do it server-side with your locators). This is the only drawback I can see using this approach since you'd have to redefine fields that would be granted with inheritance. But I'll definitely give both a try again.

Re: RequestFactory .with() to access non-relation (primitive) properties?
Hi Thomas, This is great, I was hoping this was the case. I knew polymorphism worked well but I wasn't sure whether you could define EntityProxy super classes and that RF would still be able to find the super class properties from the child proxy without having to explicitly define them in the child EntityProxy. Thanks for the good news, RF just got way better.
