Undefined is not an object (evaluating 'wrapperLayout.pageY'))

[brunoczo]

I'm getting this error in IOS, does anyone know what it can be? No Android is working properly.

Edit: My workaround is edit the node_modules/react-native-sortable-listview/index.js and add the (wrapperLaoyout==null?0:wrapperLaoyout.pageY) in 3 pointis of my code

I also get this error on ios seems to happen when the drag is not completed properly.

hard to replicate in ios simulator but happens on iphone 6 device seems the scrolling on the list and drag is conflicting @brunoczo your workaround does fix the error page displaying but it never retrieves the correct scroll offset with wrapperLayout as it is always set to 0.

Commenting out the InteractionManager here (https://github.com/deanmcpherson/react-native-sortable-listview/blob/master/index.js#L458-L460) fix it for me. Not sure if it's something that I'm doing in my application but InteractionManager.runAfterInteractions was never triggering so the layout was never getting measured.

@adamjacob You mean

componentDidMount() {
    // InteractionManager.runAfterInteractions(() => {
      this.timer = setTimeout(() => this && this.measureWrapper(), 0)
    // })
  }

Right? For me, it also work. Thank you.
