Show Numeric Keypad

I have a Numeric Text Field object on my HMI. I’m using the line of code: system.gui.showNumericKeypad(event.source.intValue) in order to pull up a numeric keypad. when a number is entered and I hit “Ok”, that number is not returned on the Numeric Text Field object. I’m I missing something here?

The value entered is returned by the function, not placed in a field. You’ll have to place it where you want it.

Is there a call to place the entered value somewhere? I am running into the same issue when returning from a different screen and trying to get the onscreen keyboard to open on a selected field.
