If you are new to Flex you can use a generic array collection to populate a datagrid without any major issues. They work fine. You can go back later and turn it into an array of typed objects if you encounter a situation where this is beneficial.
As for your question, the list of data sources is probably very small. I would send all the details into Flex with one call. It will be easier to code and I doubt you are going to noticably impact RAM usage or bandwidth by doing this. -Mike Chabot On Sat, May 17, 2008 at 3:15 PM, Dan Vega <[EMAIL PROTECTED]> wrote: > Here is what I am trying to do and it may make more sense.
