this.refs.wrapper.measure return undefined with react navigation or other same library

Hi,

I spend many hours on this issue.

When you use react-native-sortable-listview on a screen load with react navigation but this screen his hidden, this.refs.wrapper.measure will return null for each data only on android.

To solve this issue i reload the entire screen when i want to navigate on with navigation.replace("yourScreen").

I think there are a better solution. But if you have the same problem this solution work fine.

Start by reproducing the Android behavior with react-native-sortable-listview inside a screen hidden by React Navigation, focusing on the this.refs.wrapper.measure entry point. Compare measurement results before and after navigation; done means the wrapper returns usable measurements without requiring navigation.replace or a full screen reload.
