Accessing exception information in an event handler method

[Former Member]

Hi,

I am trying to handle an event thrown by a fatal exception. I am able to capture the event in this event handler method. However, I need to access the PREVIOUS of the exception in this event handler method and am not sure how to do it.

Can some one please help with this?

Thanks

Hi,

Maybe you can use the object SENDER that the event export. Sender is a object reference for the previous objects.

Exemle:

methods USER_COMMAND

for event USER_COMMAND of ZCL_MAR_MVC_CONTROLLER

importing UCOMM SENDER.

Hi Marcelo,

Thanks so much.

Unfortunately this event does not have any parameters defined and is not easily modifyable. Is it possible to acces the info in this case?

Thanks

Hi,

Look at this code end check if your program works in the similar way.

Here, i'm changing an atribute from one class from other class.

If it doesn't works and you can't change an atribute directelly, i really don't know other way to do this.
