Neil Rackett updated FLEX-34321:
--------------------------------

    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:

# Publish a Flex app to an iPhone or iPod touch
# Tap on a <s:TextInput> component, the keyboard will appear
# 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.
	at spark.components.supportClasses::ScrollableStageText/endTextEdit()[/Users/aharui/flex-sdk-4.12.1/frameworks/projects/mobilecomponents/src/spark/components/supportClasses/ScrollableStageText.as:1958]
	at Function/http://adobe.com/AS3/2006/builtin::apply()
	at mx.core::UIComponent/callLaterDispatcher2()[/Users/aharui/flex-sdk-4.12.1/frameworks/projects/framework/src/mx/core/UIComponent.as:12764]
	at mx.core::UIComponent/callLaterDispatcher()[/Users/aharui/flex-sdk-4.12.1/frameworks/projects/framework/src/mx/core/UIComponent.as:12702]


Quick fix:

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