[Seaside] hand-written javascript in Ajax

Thanks for your assistance.

I know how to put the link into Google Maps so I am covered there.  What I
need is basically this:  a link that provides something like
"javascript:addToCollection('123456');".  When the user clicks on the link
it makes an Ajax call and adds to a collection on the server.  123456 would
be a code that I can then use to address the marker on the google map.  The
point is I need to build the addToCollection links on the client side in
javascript, so I assume I need to generate a Seaside wrapper function which
then carries the 123456 parameter into my callback.

I tried to use the code you provided in one method and I get:

MessageNotUnderstood: SUScript>>render:

I fiddled around in the debugger, but was not sure how to resolve this.  I
tried using #render:on: and didn't get much better results.  Am I using an
out of date Scriptaculous package?
