It's extremely frustrating that virtually ALL the samples use
hard-coded datasets even for some advanced features instead of
using dynamic data coming from a database or xml file or web
service, you name it.
All the tutorials that I can google all seem to be too simple
(good to get key concepts across) but not good enough as a guide to
develop real-world application. People, Adobe
developers/programmers, PLEASE, add some sample source code for
interacting with the datasource mentioned above.
You can generate your own sample application that uses a
database as a source of data, through the use of the Database
Wizard. You can access it via the Data menu in Flex Builder.
The wizard will ask you for information on connecting to your
database (a wide array of database types are supported) and it will
generate server-side code to interact with the database as well as
a Flex application that uses that data.
