--------------------------------------

             Summary: RTE null object reference in ViewTransitionBase.captureEndValues() when
Skin does not provide an ActionBar
                 Key: FLEX-34006
                 URL: https://issues.apache.org/jira/browse/FLEX-34006
             Project: Apache Flex
          Issue Type: Bug
          Components: Mobile: ViewNavigator
    Affects Versions: Apache Flex 4.11.0
            Reporter: Vincent Spallek


Steps to reproduce:
- Create a Skin for ViewNavigator that does not provide an actionBar which is not a required
SkinPart, see ViewNavigator
- Apply that Skin to a ViewNavigator
- Add a View that navigates to another View via navigator.pushView()
- In that second View, call navigator.popView()

Expected result:
The default backward transition is played, and the first view ist diplayed again.

Actula result:
this.actionBar is accessed, but it is null:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
