Hi
Do you mean via App Settings like so:
https://maps.google.com/maps/api/js?s...

This generates the warning in Appery test:
Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.

Ahh thank you! It has been difficult trying to figure out what what going on. When the bug is fixed, I will not need to do any hand editing after export right right?

the list always works- the detail pages (2nd link) the list items point to do not always work.

the google map is on a different page. It works when I do not click on the map then click back to problem page or previous list. The list works fine, the page works fine...until you click on map button at bottom to go to map page.

I have commented and factored down what I am doing. The problem seems to be related to a google map component on related page. I reported a bug regarding map component a while ago. I have shared my app with more description via email to see if the issue relates to the map bug.
