Can't get an app to run in Flash Builder 4 using Robotlegs
Hello,
Let me start by saying I'm still relatively new to Flex/Flash Builder, and very new to Robotlegs. In order to learn both a little better, I've been searching for Robotlegs tutorials. I came across the video here http://www.numbknuckle.com/robotlegs-simple-walkthrough/, which was exactly to type of "getting started" tutorial I was looking for (I apologize, I don't know the name of the author).
I'm using the new Flash Builder 4, while the author is using Flex Builder 3. I was able to make the appropriate changes in order to avoid compilation errors (like placing the Context declaration inside Declarations tags and replacing Canvas with Group in the SimpleText.mxml component), but when I get to the point of running the app for the first time (about 9:45 into the video), I see nothing. In other words, the app launches just fine, but there is no visible TextArea component as there should be.
Shouldn't this work just fine in FB 4? Am I doing something incorrectly? As I said, I have no errors in the project. The app launches without error. I'm just not seeing the TextArea. I'm assuming something is not getting added to the contextView. But I have gone through the video twice to verify my code and it looks okay. Maybe there's some other step that's necessary to make it work with FB 4? Wondering if someone can check it out and let me know.
Thank you,
Chris Sheffield

I have a bit of time today. I will take a look at Brian's video and create the source in FB4.

Here ya go. I imagine it is because he is addChild on the application (contextView) and with Flex 4/Spark you need to addElement. Notice how I cast it. Frankly, I wouldn't do this adding of views in a command. Instead I'd mediate the main application and add the view there where it is properly casted, but irrespective of that I've attached the demo in Flex 4.
Cheers

Wow, thanks for the quick turnaround Joel. I'll take a look at this.

How easy is robot legs to use with the data centric generation stuff in Flash builder 4?
