if I use both Dropdown and OnValueChanged, the OnValueChanged method will execute twice.

Here is my code:

public enum Mode
{
    Normal,
    Url
}

[NaughtyAttributes.Dropdown( "modeValues" )]
[NaughtyAttributes.OnValueChanged( "OnModeChange" )]
public Mode mode;

NaughtyAttributes.DropdownList<Mode> modeValues()
{
    return new NaughtyAttributes.DropdownList<Mode>() {
        { "Normal",   Mode.Normal },
        { "Url",    Mode.Url },
    };
}

void OnModeChange()
{
    print( mode );
}

I use both Dropdown and OnValueChanged. It appears the method OnModeChange() executes twice.

I'm using Naughty Attributes 2.1.4.

This problem is not limited to DropDown. AllowNesting also reproduces it, and I'm guessing most other Naughty Attributes do too.

NaughtyEditorGUI.PropertyField_Implementation calls propertyFieldFunction.Invoke, which eventually calls PropertyDrawerBase.OnGUI, and both call PropertyUtility.CallOnValueChangedCallbacks. Is this intentional?

I also noticed this issue.
