NT 8 Crash when loading indicator

[ElectronicLocal]

I am porting an indicator from NT 7.
It is a simple oscillator with overbought/oversold lines.

I started from scratch in NT 8 and began adding the code.
It began crashing when I had the combination of a custom data series being passed into an EMA indicator AND the two overbought/oversold lines.

To try and isolate the problem, I created an indicator that only has the custom data series being passed into an EMA indicator (see GTest.cs).
It works.
Then I created an indicator that just had the oscillator plot and lines (see GTestLine.cs).
It works.


When I combine the two (see GTestWithLines) it crashes NT 8 when loading on the chart.
It regularly produced the same exception. (See attached trace file).

In addition to the crash itself, the other problem is that I have try/catch surrounding all my code and it never catches the exception.
Why is that?

Can anybody shed some light on this?
Again, The offending code is: GTestWithLines.cs

The issue is a result of the NS Wizard AddLine generation which is incorrectly adding a public series<double> and attempting to get a Values[n] series which does not exist. We are looking into #8403.

The reason your try-catch blocks did not execute is that the exception occurred in the region properties, specifically under the Upper/Lower getters. If you added try-catch here, you would see the exception.

However there is more going wrong under the hood here we needed to look into and still results in a crash... the attached should get you on your way though.

Thanks for the report!
