[Seaside] jQuery html replace

[Julian Fitzell]

Erm... not sure what you mean.

The rendering block needs to be invokable later, long after the page
has been rendered and the original canvas (in the method parameter
'html') has been cleaned up. In order to make this work, the rendering
block gets passed a new canvas each time it is invoked (via the block
parameter 'r'). So you need to make sure that you only use the new
renderer and not the old renderer from within that block (not that the
Slime package provides Lint tests that will catch this for you).

Also, remember that the #render: method expects a "renderable" object.
This could be a Component, a Block, or any number of other things. I
assume your #renderResultsOn: method was returning self and that was
causing the whole Component to be rendered again each time the block
was called.
