Hi John,
Sorry if I missed the point but I'm not entirely clear on what you're
trying to do here. Do you want to unmarshal your XML into an object
graph of custom classes? I don't understand how the multiple
renderers comes into it. What is the XML describing? Is it a result
set or something less regular?
With regard to point 2, I think anything can be a dataProvider if it
implements one of the accepted interfaces. IList, ICollectionView etc.
Cheers,
Lach

Hi, I need a hand here ...
I have an app which reads an XML file, shoves everything into an
XMLListCollection and then renders the collection to a one-column
datagrid. Each row of the datagrid uses a (state-based)
customItemRenderer [don't get me started on the problems I've had
with ViewStack-based approach].
Anyway, it seems to work fairly well ... but I've now been asked to
take a slightly different approach. The XML needs to be shoved into
an Object Model (a custom DOM), so that the same data can have
multiple renderers/converters created in the future (not just
"renderToScreen")... renderToPDF, renderToCSV, etc. Now there are
notes in the PDF docs on creating a Class-based model ... I figure
I'm gonna create an array of Objects, each one typed as they need
to be, you know Bool, Text, Graphics, customSetOfAttribs,
whatever ... custom addItem and removeItem functions which use
templates for each Object type.
1. Any comments on my methodology?
2. How do I assign an ActionScript class as a dataprovider (for a
datagrid)?
Thanks.
Cheers
John
