Howard M. Lewis Ship commented on TAP5-185:
-------------------------------------------

Some aspects of decoration have changed since this issue was written and I may (may!) have improved the docs already.  I'll check.

> documentation for decorating services should have an additional example
> somethig like this for situations where we are decorating a specific service,
> and not using some general decorator factory
>     public static ComponentMessagesSource decorateComponentMessagesSource(Object delegate, Logger logger){
>         return new ComponentMessagesSourceDecorator((ComponentMessagesSource) delegate,logger);
>     }
> this should be documented because the decorator is ignored if above is chenged this way
> (this is somehow more logical than above but doesn't work)
>     public static ComponentMessagesSource decorateComponentMessagesSource(ComponentMessagesSource delegate, Logger logger){
>         return new ComponentMessagesSourceDecorator(delegate,logger);
>     }
> I think that the second sample caused exceptions in earlier versions....
> (the exception was even more misleading)
> of course, if not too much trouble, tapestry ioc could be modified so that the second example works as well
