    NT8 v8.0.15.1 -- Strategy Builder "Unhandled Exception"

    The impact of this error is substantial, so I'm starting a new thread though several others (?) do seem to talk around it. Per email with NT Platform Support, "QA" is aware of this, and plans a fix for v8.0.16 -- which cannot get here too quickly, as this has a show-stopping high impact on my strategies.

    Symptom: The Strategy Builder process cannot be completed, as this error occurs --> "Unhandled exception: Object reference not set to an instance of an object." In C#-speak, this is a NullReferenceException.

    Cause: Per Josh, "The bug here emerges when using an extra data series and then setting any internal variable as an action in the Strategy Builder."

    Supplementary: I have also seen this error when using a direct reference to a text string to set a string variable, even when an extra data series is merely invoked (but not actually used in any Set conditions).

    Yes, I just stumbled into this 1 min ago myself:

    Make sure to get this fixed... I wonder how is it possible that you did not caught this error before... to me it looks like basic debugging.


    Sorry for the comment, Im just frustrated...


    Thanks for the support

      Hello MH358,

      Thank you for your note.

      I see this issue is slated to be repaired in V8R16.

      Is there something new you have to report or add?

      I look forward to your reply.

        Is there a central listing of fixes planned for V8R16...? I posted this to the forum for other users as I was surprised someone else hadn't, especially given its impact, with the thought that others might be seeing the same problem. But if a planned-fix list exists, that would be of great interest.

          Hello MH358,

          Thank you for your response.

          There is no central listing for the public on the fixes planned for the next release. We cannot guarantee implementation of any fix until the release is made public.

          Please let me know if you have any questions.
