Exception handling

This is weird, didnt the exception set the value of the datafield to true as per your code?

Hi Yousef

My datafield equals true but my workflow status is error. I want it to be "active" because I handle my exception.

Then I think you need to disable exception handeling, and on your server event, write a try-catch block where you expect exception and silently do what you want.

Enabling exceptions will definitly put the instance in error state.

hope this helps.

I'd think that at any time you have unhandled exception or handled but with a throw ex, it will cause the workitem to go into Error mode.

If you simply have this then it will not error but you are hiding the true error.

try

   x = 0 / 0

catch

    'do nothing

end try

Hi,

I have an activity which consists of several server events (C# code). Let's call them Event A, Event B, Event C. I have wrapped the code with try-catch block in all the server events and will throw exception whenever I catch any exception while calling my wrapper code (reference dll). Let's say Event C has hit an exception; if I retry from the management console > Error Profile, would K2 reexecute Event A and B as well? I only want to retry from the point of failure onwards.

Thanks.

K2 retries from the code from the event at which it failed.  So in your example it would re-execute the code in Event C if you clicked on retry.  It would not re-execute Event A and Event B.

Note that it would re-execute the entire code in Event C.  It doesn't just just retry the line that generated the error which could have implications depending on what your server event code is actually doing.

For example after the retry the ServerEvent2 datafield value would be the datetime of the retry and not the datetime when the first error occurred. 

             try
            {
                K2.ProcessInstance.DataFields["ServerEvent2"].Value = DateTime.Now.ToString();
                int x = 0;
                int y = 1;
                int z = y / x;

                K2.ProcessInstance.DataFields["ServerEvent2"].Value = "test";
            }
            catch (Exception ex)
            {
                throw ex;
            }

Thanks, Tim.
