NinjaTrader Editor Reports Exception

[nientenickgraze]

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.

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

Hello nientenickgraze,

Thanks for reporting this.

Can you please clarify what steps you took that result in this?

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!
