    NinjaTrader Editor Reports Exception

    Hello,

    as attached, I see the ModelViewViewModel of NT gets broken once I opened the playback mode to the Script Editor.
    Here you have the part of the trace file that tells me this:

    2015-08-01 22:36:36:150 *************** unhandled exception trapped ***************
    2015-08-01 22:36:36:150 Object reference not set to an instance of an object.
    2015-08-01 22:36:36:165 System.NullReferenceException: Object reference not set to an instance of an object.
    at NinjaTrader.Gui.NinjaScript.Editor.EditorViewModel .ApplyProperties()
    at NinjaTrader.Gui.NinjaScript.Editor.EditorViewModel ..ctor(EditorView owner, UIElement treeView)
    at NinjaTrader.Gui.NinjaScript.Editor.EditorView..cto r()
    at NinjaTrader.Gui.ControlCenter.<OnNinjaScriptEditor >b__f1()
    at System.Windows.Threading.ExceptionWrapper.Internal RealCall(Delegate callback, Object args, Int32 numArgs)
    at MS.Internal.Threading.ExceptionFilterHelper.TryCat chWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)
    2015-08-01 22:36:46:404 *************** unhandled exception trapped ***************
    I need to stress that, once this error has occured, I can no longer open the script editor even in safe mode !

    Thank you very much for your attention,
    Andrew

      After the palyback NinjaEditor stopped working...

      Thank you Brandon for your response.

      I had cancelled the database first (removed phisically files from the db NT8 folder) after that I re-downloaded the db files from my IQFeed data feeder account (tick, day, minute) and the NinjaScript editor crashed genertaing the error.

      I hope this may help you: from the help file I see you used MVVM design pattern to create NT8 app, could it not be a correct separation between the layers ? Data layer and presentation layer seem somehow corrupted. Of course, these are my 2 cents.

      Thank you
      Andrea

        Hi nientenickgraze,

        I am unable to reproduce this thus far using the steps you mentioned. I might be missing a step somewhere. Can you record a video and send that to me so I can follow along?

        Go ahead and send that to platformsupport[AT]ninjatrader[DOT]com. In the body of the message, please put "ATTN: Alex" and the URL for this forum thread.

        Thank you!
