How to fix: 'Unable to deserialize user data' message

[GaryAlbers]

I have a strategy that gives me the attached error dialog when I load it.
I believe the error dialog is referring to the code below.
I cloned the code from an indicator which had no errors.
Can anybody point out what i did wrong?

 
        [Description("Swing Text Font")]
        [GridCategory("Parameters: Indicators")]
        [Gui.Design.DisplayNameAttribute("Swing Text Font")]
        public Font SwingTextFont
        {
            get { return swingTextFont; }
            set { swingTextFont = value; }
        }
        [Browsable(false)]
        public string SwingTextFontSerialize
        {
            get { return NinjaTrader.Gui.Design.SerializableFont.ToString(swingTextFont); }
            set { swingTextFont = NinjaTrader.Gui.Design.SerializableFont.FromString(value); }
        }

Thanks,
Gary

Hello GaryAlbers,

Thank you for your post.

I do not see any issues with the code you provided, can you provide us the full strategy script?
