I'm not familiar with PowerBuilder but I have a task to create Automatic UI Test Application for PB. We've decided to do it in Python with pywinauto and iaccesible libraries. The problem is that some UI elements like newly added lists record can not be accesed from it (even inspect32 can't get it). 
Any ideas how to reach this elements and make them testable?
I've seen in AutomatedQa support that they a recipe recommending using msaa and setting some properties on the  controls. I do not know if it works.
