Hi ,
This is regarding Peter Simpson's post of the Airports Module example pertaining to Lazy Loading:

The program is great !
However, when I press the 'Back' button on the Smartphone when the program is running in the 'Debug' Mode, I am getting the following error:
Unexpected event (missing RaiseSynchronousEvents): txtsearchfilter_textchanged
Check the unfiltered logs for the full stack trace.
Error occurred on line: 79 (Main)

Question: 1) Has anybody encountered a similar problem (or is it only on my system)?
2) Can we get a solution for the same?
Thanks.
