Symptoms

SharePoint list does not see K2 objects linked to it.
 

Diagnoses

There is a site collection with a SharePoint document library having K2 smartobjects linked to it.
All objects can be seen in K2 designer, but when I go to the SharePoint document library - Application (K2) you just have two options "Create new application" and "Deploy an application".

Instead, Initially you should be seeing a list of smartobjects linked to the library. This functionality worked before on the same site and the library.
It is needed so when you change the columns in the SharePoint list, I have an option to refresh SmartObjects.

How would you link the library back to K2.

 

Resolution

You can to get around this by going to the document library and create a new application. You can then select the Smartobject that was created and it should have all latest fields. Views and forms linked to it automatically and everything should work as expected.
