Bars.IsFirstBarOfSession NullReferenceException

Got this exception now in RC2.
Also read this http://ninjatrader.com/support/forum...null+reference
Now this is in archive. Problem solved in release?

Hello ren37,

I am not aware of any specific changes in RC2 which would have addressed this scenario.

I reviewed the trace files but I'm not exactly certain of the context. I noted it was shortly after the application started, but before you connected to a data provider - since it was OnMarketData, were you working with tick replay?

Was the error during the initial startup/load process? Or was it after some user action e.g., you duplicated a tab, or drag/drop an indicator for instance?

I'm not aware of any situation where the objects used to return that property would be null, so we will need a bit more information regarding the environment it occurred in.

Thanks

Hello

Yes, it was tick replay option checked.
I had only one bar load setting in data series options (one bar on screen in fact), but had this exception on bar #6!

Error was during the initial data load process. No user action at all.

About 30 mins after I got this but without any exceptions.
This shots are after connection to data feed.

Thanks, we're running more tests around that area.

I apologize but I'm not quite sure what you are trying to show with these screenshots (although I see the bars do not match) - are you suggesting this null reference error had a downstream effect? Or is this a separate issue you are looking to report where two chart tabs are not in sync with each other?

Last price on 2nd chart is 2130 (see price marker) and some latest bars missed.
But actual data are coming in OnMarketData() (see level 2 and tape drawings).
As I remember on this run I didn't see Null ref exception.
