Unable to download the source code. When I got to page [visit link]

I received a Coldfusion error:

A License exception has occurred.
You tried to access the Developer Edition from a disallowed IPThe Developer Edition can only be accessed from 127.0.0.1 and two additional IP addresses. The additional IP addresses are: 209.85.238.20,87.194.221.84

There are so many issues encountered with the tutorial apps out there, that dont work when people follow the isntructions exactly. We need apps that work when followed, and we need downloaded source code that will actually be there.

I am familiar with ColdFusion but completly new to Flex. I can't get the code to work and I am very frustrated. This isn't a good first application example if we can't work the code. Does anyone have the working source files? If so, please post a link to the corrected files. Thanks!

I love all the article put out by sys-con and found that they are top quality, that is until this one. I have been struggling with learning Flex and found this article and initally was excited because it looked like the article that was going to clear things up. Until I started in and realized that this article is full of mistakes. Flex is VERY case sensitive where as ColdFusion is not. Since this article is target at ColdFusion developers you need to make sure that the code is correct expecially in the area of case sensitivity because we ususally don't think in that manner (it is "faultString" not "faultstring"). Also you need to make sure that you are using the same name for functions. You have us call the addItem() function through a click event but then on the next page we create the saveItem() function to handle that click event. This won't work! Then we need to make changes to the generated CFCs. You show us the two lines of code that we need to add and simply state that they "should be added to the 'create' method." Ok, but where in the create method. I moved them all over and I continually get errors. I have yet to find a competent article for the Flex "newbie" that achieves its goal of showing how to do basic updates and adds with Flex and CF. I thought that this was going to be the one. Guess I was wrong!

I'm glad it's not just me! I've had to put this aside for a couple weeks to work on a CF project. Hopefully I can get back to it later this month. If you figure something out, let me know and if I figure it out, I'll let you know. In the meantime, maybe a savior will come along for both of us!

KTK - I have the same problem and I followed all of the instructions exactly.

Uf!

I'm getting an error that says "A file found in a source-path must have the same package structure '', as the definition's package, 'Task'. I've been beating my head against it for hours and can't figure out why I'm getting the error. Any ideas?

OK - I'm a bit new to both Flex and CF, but have been implementing the tutorial fine up until: "Going back to the main application file (mytodolist.mxml), switch to the design view and drag a new panel and inside drag your EditForm component." When I drag the EditForm component onto the panel, nothing happens. Would it be possible to explain exactly what has to be done here? Many thanks.

Problem solved - I was trying to drag the EditForm.mxml - but it's the EditForm component(as it says in the tutorial)which needs to be dragged - this is found in the custom component folder.

I found myself a bit confused to follow this article as it is a bit out of the real target - which is bringing new people to use Flex and ColdFusion. As a ColdFusion programmer, I found very interesting to try this example with Flex. But after couple paragraphs, started to be confused on which file I was suppose to put the code as Flex is a real new thing for me - I'm sure it will be the same for few of us - if it is not more! We use to read article where editor just put rectangle on source code by page - but this article seems to have a different goal!

I will figure out what was wrong in the code because I think I can but what about newbies!!!

This was my personal feedback!
