Froze Script Editor

[NJA_MC]

I got a strange situation while working on a NinjaScript program that uses OnMarketData/Depth. Within those overrides were classes that were no initialized.


In the output window I got an error stating the class was not initialized "
Error on calling 'OnMarketDepth' method on bar 7977: Object reference not set to an instance of an object." and then the box below popped up. I started to simply "IGNORE" this box maybe 10 times, then the editor Froze.

Most of the rest of the system was responsive, it was in Playback mode.

This could be a bug in our code or a bug in your code (If I understand you right and your working with OnMarketData handlers)

Essentially it means you tried to unsubscribe an event handler but it didn't exist if I'm reading the error correctly.

Lets start here->

You working with any event handlers in your code?

Can you reproduce the problem?

I wrote a quick Strategy & indicator that produces the error shown in #1. This might help you find the exception. This seems like an awfully deep catch which messed up something. deep in the initialization.

This will be fixed with NT8B2, issue #8181. Thanks for reporting.

On your script (in case it's not clear); the problem was exhibited by a coding bug where you did not instantiate 'm_dummyClassNotInitialized' before calling 'm_dummyClassNotInitialized.Failed()'
