Destination Rule and Escalation.. help!

Hello everybody,


I have a process that has an approval activity.  Within this activity, There is a destination set of 5 approvers.  The way I have setup the Destination rule is as follow:


 



  • All at once
  • Create a slot for each destination
  • Resolve all roles and groups to users

Right before my InfoPath Client approval event, I have added an email event that has a customized URL to lead the approvers to their approval forms.  It is setup as follow:


<a href="http://<MOSSServerName>/RuntimeServices/OpenInfoPathTask.aspx?K2Server=<K2ServerName>&SN=ProcessId_ActivityInstanceDestId&XmlFN=<FormName>&Lib=<LibraryName>&OpenAsWebPage=True&SPURL=<MOSSURL>&Single=True" target="_blank">
Click here to action approval task</a>


As you can see, I am using the Workflow Context Browser variables from the K2 Object Browser to build my URL.


All of this works fine, until I added an escalation to this activity as a reminder.  This escalation is setup as an email event.  I have setup the recipients of the email using the Destination User checkbox (same as the regular email event). The email contains the same custom URL.


When I run the process, the Approval activity gets kicked off properly, but when it reaches the escalation, I am getting an error that says:


 


ActivityInstanceDestination property not available on given context.


What really puzzles me is that since the approval activity and its escalation uses the same destination rule and destination set, how come I am only getting the error on the escalation?


 


Thanks in advance.

The reason for this is that with an escalation the ActivityInstanceDestination property won't be available for since an escalation event doesn't have a destination user  (I may be wrong so perhaps someone can double check me).  I think your best option is going to be to send a generic email that reminds them that they have a task to complete.  Typically I will include a hyperlink in the escalation email that takes the user to the K2 Worklist webpart (or an ASP.NET page to display their work items).

Add a Server Event (just before the client event on the same activity) and a Datafield in your process.


In your server events’ code, populate the datafield with the value of the K2.SerialNumber or K2.ActivityInstanceDestination.ID.


E.g. I created a data field in the process called abcd.


K2.ProcessInstance.DataField["abcd"].Value=K2.ActivityInstanceDestination.ID.ToString();


 


Use the datafield in the Escalation mail, instead of using the Workflow Context object, use the value.from your datafield to build up your URL.

Hi Vernon,


Thanks for the reply.  I came across your answer while searching the forum.  My question is, does this technique work for mutliple destination users?  Do I have to create the an activity data field (instead of a process datafield) since ideally we want 5 unique values of abcd?


 


Thanks,


Brian

That is where I ran into some limitations with being able to build up that unique URL for each of the 5 destination users.  I found it much easier to just send them an email that had a generic URL that takes them to their worklist.  I would be interested to see if it is possible to get that specific URL for each of the destination users.
