Confusion about State.Terminated

[llanqui]

Hello,

I don't understand the internal design....but State.Terminated seems to execute multiple times...to me unexpectedly.

I would hope it would only execute when the process is really terminating....

If I have instantiated object in other States, and then Dispose or want to de-instantiate them, and they are not instantiated yet, I get an error.

i only want to Dispose of objects at the Final

Or, am I missing something???

How do I deal with this?

Many thanks

i read through the documentation again...it seems that I should set a flag in State.Configured...then check it in State.Terminated

If Configured has been executed, then I can dispose of the objects in Terminated...

Would that be the right solution?

Hello llanqui,

Likely, you are setting State.Terminated for clone instances that are used for populating the UI.

Please review the forum post below.

As well as the NinjaTrader Lifecycle in the help guide.

For any disposable object type, check if the variable is null, if it is not then call .Dispose() on the object in State.Terminated.
