Symptoms

The client noticed that if you create a smartobject from the K2 App Management pages, that it does not appear in the process wizards when you build a workflow in K2Studio and Visual Studio.
 

Diagnoses

After you created the smartobject via the K2 App Management pages, you can "re-create" the smartobject using the K2 "Application" button. This will keep the original GUID and after that, the smartobject should be visible in K2Studio and the Visual Studio designer. (This is a bug with 4.6.8)
 

Resolution

It was confirmed that this issue was resolved in 4.6.9.
