java.lang.NullPointerException

tip

This was issue #706 in tabris-js. It happens when you have a switch in a CollectionView that is child of a Tab. Updating tabris or changing the switch for a Checkbox seems to solve the issue.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
