Are you placing the CustomBorder class inside the folders oreilly/cookbook ?
There lies your error, your AS class has to be named CustomBorder.as not
Sorry I check my files again and I cant find where the spelling wrong ?
In the testSkin.mxml file I can track the class defining by using the F3 key when the cursor focus on the class name.
I think that can prove I have no spelling wrong in that 2 simple files.
In AS3 your class name has to be the same as the file name.
