Question -- tutorial uses async, my code fails with NoMethodError?

[myob]

I've just started using Elevate and am very impressed. For simple 'gets' with no parameters, it's just what my team and I need. But no matter what I try, I can't seem to pass a parameter into the task for 'posts'. The working examples all either use hard-coded values in setting up args or define tasks with async. I can't use the former because the argument is instance-level dynamic, and task creation is class level. I can't use the latter because async fails with NoMethodError. Worse, I can't find 'async' or any reference to it in any of the source code. Any guidance would be appreciated!
