Hmm... this almost works. It does update multiple elements, but it's a bit
too simple to do what I need. Here's kind of what I'm trying to do, syntax
just made up for second add...
html script: (html evaluator
callback: [ :script |
script add: (script element id: 'id1'; update: 'price here').
script add: (script element id: 'id2';
render: [:r |
self allPrices do:[:each |
r text: each.
r anchor callback:[self bookRate: each]; text: 'book
Ok, updating the first element, simple text content, works great, but
updating the second element, need to insert multiple child elements with
anchors and callbacks, need a rendering context, can't figure this one out.
