Unhandled Exception, Strategy & Market Replay Connection

[californiaruby]

I used the wizard (Tools | New NinjaScript | Strategies) to create the simplest possible strategy. To do this, after giving the strategy a name, I clicked Next until Finish was available and then clicked Finish.

I using a market replay connection. I am running this copy of NT on a development machine and have copied the recorded data from my trading machine. I copied all folders and files underneath C:\Program Files\NinjaTrader 6\db\data.

When I add this strategy (Strategy tab | right-click Strategy | New Strategy) , I get an unhandled exception popup that reads, in part,
System.NullReferenceException: Object reference not set to an instance of an object.
at NinjaTrader.Strategy.StrategyGridDisplay.AddStrate gy(StrategyBase strategy, Int32 rowIndex)
at NinjaTrader.Strategy.StrategyGridDisplay.OnNewStra tegy(Object sender, EventArgs e)

I do not have this problem when connected to simulated data.

I am using 6.0.0.6.

What am I doing wrong?

Thank you.

I have a complex workaround -- sorry it is so long.

1)
a) Global simulation mode off
b) Connect to market replay
c) Attempt to load the strategy. continue after exception message.
d) Disconnect from market replay

2)
a) Global simulation mode on
b) Connect to simulated data feed
c) Load the strategy
d) Disconnect from simulated data feed

3)
a) Global simulation mode off
b) Connect to market replay
c) Attempt to load the strategy. continue after exception message.

4)
a) Global simulation mode on
b) Load the strategy

Strategy is now loaded.

I suggest updating to latest NT6B7 and trying to reproduce. Note: Replay files now are in <my documents>\NinjaTrader 6\db\data.

If you still can reproduce then I would need:
- market replay data file(s)
- strategy
- which instrument and timeframe are you running the strategy on?

Please send all to "dierk AT ninjatrader DOT com".

Thanks
