I'm building a phone app. It uses galleries as dropdowns for selecting values that populate a form on the final page for submission. In the past, I've been successful by just using variables, and having each screen populate a variable. This time, I've tried using a collection, and it all works perfectly in the editor and iOS, Web.
THE PROBLEM IS: Even though everything behaves as expected, I get the red error message "An error occurred on the server." I'm patching directly into a collection when this error occurs. The data is still patched into the collection. As far as I can tell, no error has occurred. I believe this is a bug. I can't even tell what kind of error it thinks has occurred. Can I supress this message?
My planned workaround is: I'll just have to use 20 variables instead of 1 collection with 20 columns. That's lame, but working code is better than false error messages.
