CFDJ article: Your First Flex Application with a ColdFusion Backend

CFDJOur Flex "My To-Do List"  tutorial has been published in the June issue of the ColdFusion Developer's Journal (and we made the front page!). It can be read online and the source can be found at the project page.

Although simple, we tried to be as complete as possible for "your first Flex app". It shows how to use the CF wizards, use events, create custom components and use the RemoteObject tag to send and retrieve data from the server.

    Hallelujah! Thanks for the article... Coldfusion/Flex is the direction I'm heading for UI-centric applications so I appreciate articles like this one.

    I get the following error in Flex Builder right at the end of step 2 trying to run the app. Any idea what caused this?
    1119: Access of possibly undefined property faultstring through a reference with static type mx.rpc:Fault.

    I meant to say at the end of Page 2, when reading the CFDJ online article.

    Hi, loved the tut, really set me off with flex and now think its cool as!

    Would there be any possibility of any guidance to deploying the project to a remote server as opposed to localhost? Cannot get any clear straight forward instructions on how to do this on a project designed and tested on a local server?

    Cheers,

    Si

    Hey Troy, I had the same problem when I implimented some of the concepts from the tutorial into another app, stuffed if I can remember how I solved it though, could you post your code so I can try and jog the ever fading brain cells =)

    Troy,

    I think it's faultString (capital S). Lemme know if this works.

    Hi all,

    I get a weird error.

    "Error Executing Database Query. Out of range value adjusted for column 'priority' at row 1"

    I say weird as we don't have any way of manually inserting a value for the priority column. I'm using MySQL 5.

    Thanks,
    Alexander

    Great tutorial. If only I could get it to work. I get "Unable to invoke CFC" when I try to run it in the bowser.

    I know my cfc's are there as I can see them when using the componentdoc.cfm utility but for some reason flex can't find them. Also I can't see any cfc's when using the Services Browser in flex builder 2. My RDS is set up correctly so it isn't that, can anyone help.

    Rregards, Richard

    I got the same 'Unable to invoke CFC'. When I verified the Coldfusion data sources in the Coldfusion Administrator it all worked.

    Hi Laura,

    I want to say thanks to you and Nahuel for spending the effort to create this tutorial and your contributions are very valuable and well appreciated. I have been hearing a lot of great things from Tom about this technology, and I always wanted to get my foot in the door with it. I will give this tutorial a shot as I have no doubt that it will help me. Thanks again and take care!
