How to catch BusinessException in custom built behavior?

Hi Charles,

I was trying to build a custom behavior to catch exceptions and publish a notification, and also tried to follow this tutorial about Subscribing to Error notifications from ParticularSoftware site, but I can’t catch any BusinessException thrown.

In my system I’m not using the Command method in the class BusExtensions in Aggregates.NET, I’m using directly the bus.Send like in the method PassiveCommand in the pre-mentioned class.

I looked in the source code and figured out the library is handling it in the ExceptionRejector class, any way to catch the exception? and way to remove this step? because I couldn’t, 3 steps are depending on each other:

• CommandAcceptor
• UnitOfWorkExecution
• ExceptionRejector

I tried this and it’s not working:

endpointConfiguration.Pipeline.Remove("CommandAcceptor");
endpointConfiguration.Pipeline.Remove("UnitOfWorkExecution");
endpointConfiguration.Pipeline.Remove("ExceptionRejector");

The steps are as following: MyFailedMessageNotification -> ExceptionRejector -> MyHandler -> ExceptionRejector (this one swallows the exception at line 53 and do return instead of throw again) -> MyFailedMessageNotification

There steps between those I didn’t mention, but these are the important ones as I think.

I solved the issue by adding these two lines in the registration of my behavior:

InsertAfter("CommandAcceptor");
InsertAfter("ExceptionRejector");

One of them is not enough, it has to be both.
