[Seaside] Scriptaculous strangeness

[Keith Hodges]

Using almost latest seaside and scriptaculou , I am rendering a button 
like so:

renderEditorButtonAddOn: html
    | addId  |
   
    html submitButton
        id: (addId := html nextId);
        onClick: (self renderUpdaterElement: addId on: html);
        callback: [ self add ];
        text: '>>'.

The following code works (although there is a fleeting js error)

renderUpdaterElement: eid on: html
    (html updater
        id: id;
        triggerFormElement: eid;
        on: #updateEditorOn: of: self;
        return: false)

But this code doesnt work

 renderUpdaterElement: eid on: html
    ^ (html updater
        id: id;
        triggerFormElement: eid;
        on: #updateEditorOn: of: self;
        return: false)

any ideas why not?

thanks in advance

Keith


p.s. if I replace submitButton with button, I get a minicule-tiny-button 
once more.
