[Seaside] hand-written javascript in Ajax

[Chris Dawson]

I'm almost there.

I have a marker on the map which houses a link with an onclick handler
called 'addLocation( "123456" );'.   So, I tried to define addLocation like
this:

                html script: (' function addLocation( theId ) { ', ((
                        html updater
                        id: 'locations';
                        callback: [ :v |
                            locations add: ( myLocation new title: v ).
                            self renderLocationsOn: html.
                            ]
                        value: (SUStream on: 'theId')) asJavascript ), '; }'
).
                        ]
                    ]

This crashes my updater.  It does pass the value of theId properly as this
is stored into the MyLocation collection.  But, it seems I need an html
object renderer passed back to me.
