I current have a list item that is populated by a database API call (a simple list service). There are a couple of visible labels inside each list item and a couple of hidden labels inside each list item. The mapping populates these labels with data returned from the API call.
I think have a click event that sets a local storage variable and then navigates to a different page to display item details. (A master/detail design...)
When I navigate to the detail page, I see the exception below. However, it looks like the exception is being thrown from the "master" page where I populate the list. When I then click the "back" button from the detail page, the master page is blank. When I click the nav button for that page, it refreshes and displays the data again.
Any ideas what I've done wrong here? I've been working through this for a couple of hours.
