VerifyError: Error #1014: Class spark.components.supportClasses::ItemRenderer could not be found

I have a small code in flex that needs a very small fix, change in text field. I have never done flex programming. I downloaded the "FlashBuilder 4.7" Built a small test application. I tried to run it as Webapplication. A web page open but nothing gets displayed. Then I downloaded the FlashPlayer debugger and opened the swf file and I got the error

VerifyError: Error #1014: Class spark.components.supportClasses::ItemRenderer could not be found.

I am sure this is the cause why my application is not showing up in the browser. As you can see from the image I have attached, I have included the spark components. Have tried all possible ways that I can think of to solve this and even googled it no luck. So turning to this group to see if I can get some help.

And my project setup enter image description here

Solution

  • In the flash debugger, I was using the swf file generated in the bin-debug folder and that was giving me this error. What I did was I went to FLashBuilder -> Project -> "Export Release Build..." This created the swf file in the bin-releae folder. When I run this swf in the flash debugger, it works fine. Not sure why the debug version is not running.
