Tyson Norris commented on SLING-2708:
-------------------------------------
I'm not sure how to avoid this, other than isolating a service with proper
admin rights just for testing super types. Changing SlingAdaptable to provide
the decorated resource to an AdapterFactory sounds appealing, but I'm not sure
if or how that could be done.
> ResourceUtil.isA() fails for adapted Resources unless user is admin

> Project: Sling
> Issue Type: Bug
> Components: ResourceResolver
> Reporter: Tyson Norris
>
> Summary - adapting a Resource to a specified type, loses the ability to test
> the Resources super types using ResourceUtil.isA(), UNLESS user is admin
> 1. TypeA is defined as:
> class TypeA {
> private Resource res;
> public boolean isTypeB(){
> return ResourceUtil.isA(res, "some/type");
> }
> }
> 2. TypeA adapter is an AdapterFactory to adapt Resource -> TypeA
> 3. /some/res/path is a resource whose sling:resourceSuperType 2 levels up is
> "/apps/some/type"
> 4. In a JSP, we use code like:
> TypeA typeA = resource.adaptTo(TypeA)
> if (!typeA.isTypeB()){
> //FAIL: typeA.isTypeB() is actually true
> }
> Note that:
> ResourceUtil.isA(resource, "some/type") == true
> but
> ResourceUtil.isA(typeA.resource, "some/type") == false
> (unless user is admin)
