[Seaside] hand-written javascript in Ajax

Ok, if you don't want to update then simply use the AJAX requestor:

     (html request callback: [ coll add: 123 ])
          asJavascript

This expression gives you a string that when evaluated by the
Javascript engine triggers the execution of the Smalltalk block on the
server.

If you need to pass some data from the JavaScript world to the server
you can use something like that:

      (html request
           callback: [ :v | coll add: v ]
           value: (SUStream on: 'navigator.appName'))
                asJavascript

In this case the property navigator.appName is passed to the server.
As far as I understand you want to pass some Google Maps data there.

I write most of the examples for the mailing-list directly in the
mail-application, therefore there is usually some significant amount
of fixing needed before usage. I only try to clear what the general
approach is.

For the example in the previous mail: Remove #asJavascript, the thing
is already a string. SUScript in my Seaside 2.8 images understands
#render:.

I don't know what platform and version you are on.

Cheers,
Lukas
