Igor,
I know this is old, but in a post this morning you reminded me-it got lost
in the shuffle at work lately. When I tried to implement this, I realized
that IComponentBorder doesn't really extend from anything that can be added
to a component. It extends IClusterable, which extends Serializeable, so I
didn't know how to link it to a component.
Simply adding it to a form component doesn't work, I also looked at using
behaviors but they have "renderBefore", not "beforeRender".
Thanks!
Justin
