I had a Dropdown that worked just fine, but I changed the “selected value” to be an app var from a page var (both of type text), and now it doesn’t work. When I first tap the dropdown, it shows the option list values as expected, but when I tap one, it just shows the placeholder text (“Select” in this case.) And then when I tap it again, the only value in the option list is “Select.”
In the debugger I can see that the app var is successfully being set, so why isn’t the Dropdown reflecting the new value? And why is the option list being cleared out? The app var I used to hold the Option List values and labels still has the same options in it, so it isn’t a matter of the source data getting cleared somehow. The labels and values are identical to each other, btw, so it doesn’t matter which one gets shown.
The only thing I did to the dropdown was populate the Option list via a formula and set the Selected Value to an AppVar. Am I missing something? Seems like this should work.
App ID: 169788, testing in Android Preview app and Web preview, runtime 2.8.28.
