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.

Hello Dave,

Please provide us with a public app link (http://devcenter.appery.io/documentat...) and steps to reproduce.

Here is the link: http://appery.io/app/view/4dd72dbe-b2...

It will require Facebook authentication.

After authenticating, search for a beer (e.g. "Budweiser")

Tap/click the first search result

Click the "Add to Beer Fridge" button

From the bottom nav go to "fridge"

Tap the name of the beer - at this point you will get the error

Tap/click the back button - the fridge screen will be blank

Tap the Home button, then tap the fridge button - the fridge screen will be populated again

Hi Dave -

We were able to reproduce this error, and we have reported it.

Actually, I found the issue. I was invoking my list service on the page load, then I was invoking the same service when clicking on a list item. Must have just been a mistake on my part as I only wanted it invoked on page load. Removing the extraneous invocation resolved the problem.

Thanks!

Thank you for update.
