    CannotCompileExceptio-[source error]: no such class

      Hi, I am getting 'CannotCompileExceptio-[source error]: no such class: MyAlert' error while making a reference to an static Inner class name 'MyAlert'.



      *********below is my code***********

      Any sample example how to inject a static InnerClass is appreciated.
