In-app purchase auto-cancels in PB 2 OS

[Puzzling]

I just went back and retested my in-app purchase code. This was working under 1.7 but now I'm getting a payment failure with message "The payment process has been cancelled." I am using development mode for payment calls. I'm getting this with two devices running different versions of PB2. I'm also getting this with the payment sample application. However, everything works fine on the 1.7 simulator.

BB Development Advisor gbeukeboom investigated and found:

I did some testing and found something strange:

The WebWorks implementation for PlayBook is based on AIR. The AIR sample application works as expected (returns success when testing) but with the WebWorks sample I get the same issue you have reported. This means that the issue lies with the AIR/JavaScript layer of WebWorks.
