[Seaside] something like #callback:value: but for #html: ?

[Robert Sirois]

Use a component or use the renderer block like a normal canvasser.

The examples should load with seaside core.

> 			active: self selectedIndex - 1;  
> 			autoHeight: false;  
> 			onChangestart: ((html jQuery new

> 					call: 'load' with: (html jQuery ajax

> 						fullUrl))
> 				asFunction: #(event ui)));

> 		html div.
> 		html div id: 'header2'; with: 'header2'.

> this example is working fine, but I'm always rendering 'TEST'. I need to discriminate which content I need to render, so I need the header id value. Using #callback:value I would call something like:

> 		callback: [ :v | "Some code here" ]
> 			value: (html jQuery new 
> 				alias: 'ui'; 
> 				access: 'newHeader'; 
> 				call: 'attr' with: 'id'))
> 		asFunction: #(event ui))
> 
> but I don't have nothing similar with #html: .

> of course, I can call first a callback who sets the "current header", then make an ajax call, but that's not efficient (two calls instead one).
> so, I would like to have something like #html:value:
