Hi,

We are creating Salesforce Lightning component. We have successfully completed development of it. But while testing, we found one very weird issue.

Issue: Invalid component tried calling function [get] with arguments [v.items.7], markup://aura:iteration [54407:c]

Conditions on which issue occurs:
- When we start app, it work correctly and gives correct output.
- But after some time, if we click on any button or link, this error pop's up on screen.
- But one weird behaviour of this error is, app works correctly and gives expected output in background.



Can anyone please help us on this issue?

Thanks,
Rupali
