Could someone show me a very simple example of using Flex/Air with something other than a datagrid?  I'm trying to get a handle on using sqlite and i'd like to have something like a form or a few textinput components that you can input text into, save that data (to sqlite) and then when you reopen the app later, the data is there.

And a crude example I've knocked up stripped down to the bare basics for creating, inserting and selecting:
