>             Project: RichFaces
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: cdk
>    Affects Versions: cdk-4.5.0.Alpha1
>            Reporter: Lukáš Fryč
>             Fix For: cdk-Tracking

> The inheritance isn't inspected correctly in other cases than basic ones:
> {code}
> public abstract class C extends A {
> }
> {code}
> {code}
> public abstract class A extends UIComponentBase implements I {
> }
> {code}
> {code}
> public interface I {
>     @Attribute
>     String getAttr1();
> }
> {code}
> In this case CDK event doesn't notice there is attribute defined in {{*I*}}.
> It can be fixed either by:
> * {{C implements I}}.
> * moving attribute to {{A}} or directly to {{C}}
> ----
> CDK also takes into account whether we have abstract or concrete implementation:
> {code}
> public abstract class C extends A {
>     
>     @Override
>     public String getAttr() {
>          return ...;
>     }
> }
> {code}
> In this case the attribute won't be generated, because it is already implemented.
> The inheritance issue get then worse by inappropriate application of attribute's properties in either of those cases:
> * {{*C*}} has concrete implementation of {{#getAttr()}}, {{C implements I}}
> ** then generated component contains generated {{#getAttr()}} even though it's already implemented
> * implementation of {{#getAttr()}} is moved to {{A}}
> ** then {{#getAttr()}}  is again generated even though it's implemented in {{A}}
> ----
> I guess Those issues are caused by incomplete implementation of CDK's reflection scanning mechanisms.
