Getting null from select statement referencing a spinner control

[Bob R]

I am trying out Marathon with our javafx application.  I've had success with the recorder until I tried to interact with a spinner control in one of our dialogs.  The recorder generated the below select statement, but when I play the test script back I am getting error -

net.sourceforge.marathon.javafxagent.JavaAgentException:null: net.sourceforge.marathon.javafxagent.JavaAgentException:null

when the playback hits the select("scaleSpinner", "105")line

Any ideas or pointers?

code snip

   with_window("AUT-window-name") {
        select_fx_menu("#menu", "BOC>>Characteristic Properties...")
        with_window("Characteristic Properties")
            select("scaleSpinner", "105")
            select("scaleSpinner", "110")
            select("scaleSpinner", "115")
            select("scaleSpinner", "100")
            assert_p("nominalField", "text", "6.678")
        }

    }

Here's a snip of the generated omap data

- !!net.sourceforge.marathon.objectmap.OMapComponent
    componentRecognitionProperties:
    - {method: equals, name: Id, value: scaleSpinner}
    - {method: equals, name: tagName, value: spinner}
    created: 1608841990168
    generalProperties:
    - {name: name, value: scaleSpinner}
    - {name: id, value: scaleSpinner}
    - {name: tagName, value: spinner}
    - {name: Id, value: scaleSpinner}
    - {name: indexOfType, value: '0'}
    - {name: component.class.name, value: javafx.scene.control.Spinner}
    - {name: instanceOf, value: javafx.scene.control.Spinner}
    - {name: enabled, value: 'true'}
    - {name: type, value: spinner}

screen snip.  During the recording I clicked on the up and down arrows of the spinner.

[Bob R]

Did the screen snip get included?  I'm not seeing it.  I'll include it here as an attachment.
Also, I've noticed this line in the log from our application.  I don't know if it's related.

I have attached the UI from a playback in debug mode, stepping into the select("scaleSpinner", "105") line.  I see the 105 value is getting filled into the spinner text field, spinner control was enabled then another control in the UI enabled, then I think NPE was hit.  I found what I think is the source code file in github.  Looks like cell is null. I'm getting out of my knowledge area here so my next statement maybe be way off.  I'm thinking the ENTER after the value is sent/filled in is kicking our app off, it's running with the new value, taking the focus off the spinner control, putting it on another control, then the cell is returning null or the commitEdit is returning null because the spinner is no longer in focus.
