Exceptions in K2.net

Hi David,

K2.net will Bubble the error up from the level it occurred in to the closest Exception Handler available, lets look at the following example:

An error occurred in a Server Event , this is the lowest/deepest level that you have, it will work as follows:

If no exception handling is done in the event self K2.net will look at the

1. Event Exceptions
2. Activity Exceptions
3. Process Exceptions

If none was found in any of the Exceptions sections of the process you will find that K2.net Server will mark the process instance into error state and log an error under the error profiles in K2.net Service Manager. Please have a look at the K2.net Helpfiles under References -> K2.net 2003 Objects -> Namespaces -> Sourcecode.KO -> Classes -> Exception Context

I hope this is helpful

That largely depends on where and how you handle your errors.

If you handle the exception in Event code with Try-Catch block:
* No error in error profiles
* Process continues
* If you need error to bubble-up, you need to throw another exception i.e. Throw New Exception("I don't know what to do with this exception", ex)

If you handle the exception in the Exception code block of Events, Activities or Processes:
* By default the error will end up in Error Profiles
* Process will stay in Error state.
* If you do NOT need the Error in Error Profiles and Process to continue, add the following line: K2.AddToErrorLog = False

Hope this helps,
