I wanted to quickly write an example application and encountered the following error when I tried to use the input dialog:
B4X:
Application_Start
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
Application_Active
Unexpected event (missing RaisesSynchronousEvents): b4ipage_keyboardstatechanged:

I have reproduced it in an example project. Open the dialog with the button, write something in the box and click ok.

Thanks

It is probably related to this: Unexpected event (missing RaisesSynchronousEvents): b4ipage_keyboardstatechanged:
so the keyboardstatechanged in the main module should fix it?
Are you testing it on real device?
Simulator, is more convenient than connecting the iphone to the macbook every time.
