Error 906: No Focusable View Found

[Forrest Kendall]

I have an App that calls the screen .HideKeyboard procedure.  I want to make sure that just in case the user forgets to click (touch) the "DONE" button on the keyboard that the keyboard closes regardless when navigating to another entry field on the screen.  However, making a call to .HideKeyboard produces the following alert message:

Error 906: No Focusable View Found

This error is only displayed the first time .HideKeyboard is called when there is no keyboard displayed (If the keyboard is displayed the error does not occur).  The error does not display with the APK; it only occurs in the AI Companion when testing.

It would be helpful to have a new screen property .KeyboardVisble (or something like this).  Then .HideKeyboard could be conditionally called.  Example code below:

IF Screen1.Keyboard.Visible THEN

  Screen1.HideKeyboard

Any thoughts or comments would be appreciated.  THANKS!

Please prepare an example as small as possible, which demonstrates this issue and add the project (aia file) into this thread, so someone can take a look

Attached is a one button app.  Click the button to generate ERROR 906.

Small correction to original problem description ... Error 906 is also generated in the APK version of the App.

to fix this, just drag an empty Screen,ErrorOccurred event into the working space like this

@MIT: is this a bug or a feature?
