          Components: mx: ComboBox
    Affects Versions: Apache Flex 4.14.1
         Environment: IntelliJ IDEA 13.1.6
Flex 4.14.1.20150325
Component set: MX only (tried SPARK+MX to no avail)

            Reporter: Michel Donais


I am migrating my crusty old code from 3.6.0 to 4.14.1 (FINALLY) and I am getting an issue with a combo box. Mostly, whenever I try to press the combo box, it gives me an exception in the systemmanager getVisibleApplicationRect saying it's unable to retrieve the softKeyboardRect. That feature is optional from what I've seen, and I don't have it in my current version. It's deep in the engine and cannot really patch it easily. I could probably monkey-patch my way around, but for now, it's a bummer.

Important stacktrace with affected lines:
getVisibleApplicationRect: SystemManager in SystemManager.as:3561:
            var softKeyboardRect:Rectangle = stage.softKeyboardRect;

displayDropdown: ComboBox in ComboBox.as:1779:
        var screen:Rectangle = sm.getVisibleApplicationRect(null, true);

downArrowButton_buttonDownHandler: ComboBox in ComboBox.as:2035:
            displayDropdown(true, event);

Received exception:
[Fault] exception, information=ReferenceError: Error #1069: Property softKeyboardRect not found on flash.display.Stage and there is no default value.
