A structure in CF should turn into a Generic object in Flex (AS3). Have you checked documentation, I'm sure there is a data type map somewhere. It took me less than 5 minutes to find this page http://livedocs.adobe.com/coldfusion/8/htmldocs/UseFlexDataService_10.html .

Yes, create a Value Object CFC and a Value Object AS3 Class. Alias them appropriately. The return type from your CFC Method will be the name of the class.

If you want to know how dataProviders work, open up the framework code and take a look.

I am new to Flex and I have some questions about data types. I have a method in ColdFusion that returns a structure. I heard that this is automatically converted for me. I was wondering if anyone can point me to article that explains what types in CF are converted to in Flex. I put a break point on my result and it just looks like an object.

A follow up to that is there a method that I can use that will return the type of object I am working with?

---------
Completely separate how does the data provider for different components such as the tree and datagrid work? I have datagrids working with arraycollections and xmlcollections. Is there a specific format for the dp to work?



Thank You
