Sounds like your lawyer is telling you to lie (there was a conviction, the case wasn't dismissed) and it is never wise to lie on an employment application. One of the first things your-hopefully-new-again-employer is going to do is look at your initial application, and if you've said something different on your second application...well then the employer is going to just pass on by your application, due to your change in story.
I recommend you tell the truth on the application, and in the comments section, refer to your previous application and the fact you worked for them for about seven years without a problem.
Just curious, if it's been 11 years since you've committed a felony, why do you still have a criminal attorney around to consult with?
