KB001449 is a list of high priority issues for K2 blackpearl 4.6 and K2 blackpoint 4.6 that have now been resolved.

Issues Resolved:

K2 Server

  • A threading issue is encountered when a Call is made to the server at a time when there is a high load on the server. This causes the K2 Server to become unresponsive.
  • When a worklist item that has notifications enabled is opened an error occurs on the K2 server stating that the event instance could not be saved to the database.
  • When impersonating a User on a K2 Client Connection, and no Security Label is supplied an incorrect Security Label is used by the K2 Server. This occurs when the K2SQL label is set as the default provider in an environment where mixed providers are present.
  • When a SQLUM user starts a process and the workflow assigns the first client event activity to the process originator, the default K2 security label is used instead of the SQLUM label that started the process and the worklist item will not appear in the user's worklist. This is because the Process / Originator / Name used for setting destinations produces a value of domainname\username; if set using SQLUM the user name does not have a domain and is therefore replaced with the default label instead of the label associated with SQLUM.
  • Using the SQL Server Service, when an Insert Stored Procedure with a set identity statement is being executed, the output parameter is being set as the input required parameter.
  • In process rights it is possible to add SharePoint Groups which have a length of 255 characters, but when saving group, the name is shortened by the K2 Server as it only allows 128 characters for the name.

  • Identity Service Errors found in the log a new constraint needs to be added to the Identity table.
