Flex Monkey issue

I am trying to setup Flex Monkey.I am using Flex SDK 3.5. I added the Additional Compiler Arguments -include-libraries "../libs/automation_monkey3.x.swc"for my project in Flex Builder.Now when I runthe application and click on Username text box, I am getting the following error.

TypeError: Error #1009: Cannot access a property or method of a null object reference.

When I remove the Additional Compiler Parameters, the application works fine. I am unable to fix this issue. Any help is greatly appreciated.

Once I cleaned and recreated html-template folder in Flex builder, the error got resolved.Strange,but it works!
