App freezes with ui.Button

xgm

Hi, I’ve noticed that calling dialogs.alert() or dialogs.list_dialog() inside a function which is associated with a ui.Button, makes the app to freeze when the button is pressed. It occurs both in version 3.3 and in the new beta. I assume that it is related to newer versions of iOS, since it didn’t happen with iOS 13.

import ui
import dialogs

def myFunction(sender):
	dialogs.alert("Alert", "Do you want to continue?", "OK")
	print("Finished")
	
b = ui.Button()
b.title = "Press me"
b.action = myFunction
b.present()

@xgm try

import ui
import dialogs

@ui.in_background
def myFunction(sender):
	dialogs.alert("Alert", "Do you want to continue?", "OK")
	print("Finished")
	
b = ui.Button()
b.title = "Press me"
b.action = myFunction
b.present()
