Description

Using the current release version of Apache Flex 4.12.1, you can consistently recreate this issue and crash an iPhone or iPod touch app on iOS 6 as follows:

1. Publish a Flex app to an iPhone or iPod touch
2. Tap on a <s:TextInput> component, the keyboard will appear
3. Tap anywhere outside of the component to remove focus and you will receive the following error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Quick fix:

1. Update line 1958 of ScrollableStageText class to `if (!!proxy) proxy.visible = true;`
