Geeze, I can't even get something simple working.

I can get the example for Event.observe to work without any problem,
but I can't see to assign by id.

This example works:

<script>
        Event.observe(window, 'load', showMessage, false);

        function showMessage() {
          alert('Page loaded.');
        }
</script>


This generates "element has no properties" in prototype.js in 
line 1479

<script type="text/javascript">

    function sayHello() {
        alert( 'Hello Message' );
    }

    Event.observe( 'updater1', 'click', sayHello, false);

</script>

And the element with that id is:

<a href="http://localhost:3000/workshop/classes?o=name&amp;p=7"; 
id="updater1">Workshop</a>


Here's the try with Ajax.Updater:


<script type="text/javascript">
   Event.observe( 
        'updater6',
        'click',
        function(e) {
            Ajax.Updater('updater6', 
'http://localhost:3000/workshop/classes?o=class_time&amp;p=7', { method: 'get', 
requestHeaders: ['X-Ajax-Updater', 'ajax_table'] });
            Event.stop(e);
            return false;
        },
        false
    );

    Event.observe( 
        'updater7',
        'click',
        function(e) {
            Ajax.Updater('updater7', 
'http://localhost:3000/workshop/classes?o=class_time&amp;p=7', { method: 'get', 
requestHeaders: ['X-Ajax-Updater', 'ajax_table'] });
            Event.stop(e);
            return false;
        },
        false
    );
</script>

Then the links look like this:

<th id="updater6">
    <a href="http://localhost:3000/workshop/classes?o=class_time&amp;p=4"; 
id="updater7">
        Date&nbsp;and&nbsp;Time
    </a>
</th>

The problem with prototype and all these nice javascript libraries is
that it makes it easy for someone like me to use them. ;)

I didn't realize that the inline handlers were any different than what
you have above.  I thought they all assigned to the same event.
