First, thanks for having the patience to answer these questions.

Not hard parts, just a total cloud of confusion:
First, I'm not far enough to have a full grasp of Seaside yet. For example
(and even though it's on the first page of the Seaside Design Overview ;-) I
couldn't see that you get a HTML element 'href=' out of
( a sea:id: edit: '(edit)')
In my naive attempts, I would try to do something like:
( a href: sea:id: 'edit:' '(edit)' )
This is all part of the learning curve.
Another hard part is the kind of 'magic' that the S-Expr brings. I would not
(tr sea:id: 'app/apps'
as a translation of
So I was doing something along the lines of:
( tr repeat: sea:id: 'app/apps' )
thinking that the "@app/apps" could be substituted by sea:id: 'app/apps',
when in fact it in addition replaces the previous term so that
repeat="@app/apps" becomes: sea:id: 'app/apps'
This is the same substitution as the <a href="@edit" , so it's beginning to
sink in. I think you told me this once before, but I didn't pay much
attention. I guess I needed another round of embarassment.
I'm glad I asked, thanks
