Bug: "Set Default For <StrategyName>" in Backtest Form breaks on custom strategies

[ChiTrader2000]

Hello,

I discovered a bug in the NT 7 Beta 4 Strategy Analyzer's "Backtest" Properties Form. When I right click on the label of a field like "Slippage" or "Fill type" and choose "Set Default For <My StrategyName>", an exception is thrown.

Extra Info:

All my Strategies inherit from my own base class, which inherits from NinjaTrader's Strategy class, like this:

// here is my base class' declaration
publicclass SubsystemBase : Strategy

// here is an example of my actual Strategy's declarations
publicclass MyStrategyClassNameGoesHere : SubsystemBase

The exception is thrown both when I take this User Interface Action with my strategy base class in the "Backtest" form and when I try it for my actual strategy child class.

The trace file shows the following information:

>> All my Strategies inherit from my own base class,
This is not supported. Please try to reproduce the issue on SampleMaCrossOver and let us know if you can reproduce.

NinjaTrader_Dierk,

Thanks for the quick reply. No problem. I understand that NinjaTrader can't support all advanced applications of NinjaTrade such as my own, but I thought you should know about the problem I experienced anyway.

My strategies all inherit form a base class as well - I hope this eventually get some attention.

I cannot confirm!
My Strategies also inherit from several classes , but finally also from Strategy.

I tried to reproduce your error in the Backtest Form, but I cannot find an error.

For me everything works fine.
