Goto Activity via the K2 Activity SmartObject (in version 5)
It appears this only works when you pass it the system name of the activity which is difficult to obtain (in 5) unless you have access to the K2 database. Previously in 4.7 we could use Visual Studio to edit the properties of an activity. The workflow designer in 5 doesn't expose this and we now have to add a broker to the K2 database to grab the system name and then pass this to the Goto Activity SmartObject. This also presents itself a security risk unless you create a new account that only has read access to this datasource.
