[Seaside] Calling a JQuery enabled component from an anchor callback

[John Toohey]

I have a table that includes a html anchor with a callback in the
first column. The callback calls #render: self TestComponent when
clicked, and the #renderContentOn method of the component called is :-

renderContentOn: html
	html div id: #JPT;
		 script: (html jQuery new dialog
			title: 'Test';
			autoOpen: true;
			addButton: 'Close' do: html jQuery new dialog close);
		with: [html text: 'Hello World'].
		self halt

I get a MessageNotUnderstood: UndefinedObject>>addLoadScript: in the
browser when its called. I am trying to have a JQuery dialog popup and
allow me to edit the contents of the tablerow, but I am not sure what
I am doing wrong here.

I want to create this dialog each time a row is clicked, as I need to
populate the form with the current values. Is there an issue injecting
a script like this into a rendered page?

Thanks.
