Re: [tigerstripe-dev] Delegation Solution

[Eric Dillon <erdillon@xxxxxxxxx>]

Hi Yuri,

This behavior is indeed correct, but we never get a chance to call
IAnnotationManager.addAnnotation( (IModelComponent) ..., content) because
the adaptation can't create IModelComponent the way the Classloader is used.

(See my response to other post).
