RadListView on iOS (NS 2.5.1) - crash when tap to detail and back

[Clarence]

Hi,

I updated my app to NS and tns-core-modules 2.5.1. After that, when run my app on iOS, in RadListView, when I click on an item, browse to detail, and then back, the app will crash with the following error on console:

file:///app/tns_modules/nativescript-telerik-ui-pro/listview/listview.js:870:31: JS ERROR TypeError: undefined is not an object (evaluating 'value.view.itemView')

Kindly advice and regards

Hello,
Thank you for contacting us.

I reviewed the below-described behavior, however, the given error is too common, which prevents me from investigating this issue. 
It would help if you could provide sample project, which could be debugged locally and to give us more info about the problem. It would also help if you could send us the full log from the terminal when the error appears.

In the meantime, you could also try to delete platforms, node_modules and hooks folders. You could also clear  cache  cache clear and remove the app from simulator or device. then try to rebuild again the app with run ios.

Hi nikolay,

I managed to create a very simple app that can re-produce this issue.

You can clone the repo here:

https://github.com/skywidesoft/ns-radlistview-test.git

 

To re-produce the problem:

• Clone the repo
• tns run ios --emulator
• Click on any item and navigate to detail page
• Click Back on the action bar

The app will crash with the error mentioned above.

I updated to Nativescript CLI 2.5.2 and nativescript-ui-pro 1.6.1, but is still having this issue.

Let me know if you have any difficulties in running my app.

Thanks a lot

Clarence

Hello,

Thank you for your sample project.
I was able to reproduce this behavior while using loadOnDemandMode setup and navigate back from the details page in NativeScirpt Angular 2 project and unfortunately, I have to confirm that this is a real issue.

For your convenience, I have logged new issue, reporting this behavior.
For further info and fix, you could keep track on it.
