One primary reason for the dearth of full examples of Flex client <-> server data flow is that Flex is just too darn flexible. There are just sooo many options.
These include data model(XML, ArrayCollection,XMLListCOllection, VOs), RPC protocol(HTTPService, WebService,RemoteObject) and Data Service (LCDS and BlazeDS) and third party solutions (WebOrb, Fluorine), reasltFormat(e4x, object, text), contentType(xml, name=value), server platforms (Windows, linux, solaris), Web servers(IIS,Apache), server development platform(.net, PHP, java, ...). The good news is that if you look, you will probably find at least partial examples of most any path through that morass. And for general flex development, there are a huge number of examples available, at all levels of complexity. Just not all in one place. Start with the Adobe site, especially Getting Started: http://learn.adobe.com/wiki/display/Flex/Get+oriented+to+Flex. Also the example in Flex Builder's Start Page. And below is a list I compiled of resources. It is pretty out of date, but might still be useful, if overwhelming.

I am finding it difficult to find any Flex3 examples on how to do things with the exception of the elementary stuff such as 'Hello World'. I'm currently looking at AMFPHP to see if it will help me figure this thing out and do it with the least amount of headaches. Know where to get any Flex3+AMFPHP examples? The examples for DL at SourceForge don't have any Flex code. Thanks for looking into this. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > You can get back the plain Array by doing: > > var aRoster:Array = rosterInfo.source; > > Now, what you are doing is a bit odd.
