Issues Resolved:

K2 Server

  • Database enhancements have been made on the K2 Server and K2 Server Log databases to increase performance of large volumes of Process Instances and Asynchronous, mainly Escalations, work-loads.

For example, if the group contains users K2\John, K2\Paul and K2\Finance then the resolved group string will look as follows:
    This will cause the following error at runtime: "The User/Group does not appear to be discoverable."
  • Unable to remove a SharePoint Events Integration process that is integrated with a list or library via the K2 site Settings > Events Integration Management menu.
  • When creating a K2 Designer for SharePoint process for a Document Library that contains a folder, the process will reference the document from within the folder and will make use of SharePoint metadata and will fail on runtime with the following error "
    Message: Error 10702 An error occurred in the SharePointMetaDataService service instance. Server was unable to process request. ---> Get Meta Data failed- Specified file does not exist."
  • When a method is called in the Code Reference Event that has a RETURN type other than type VOID, and it is not mapped to a DataField or XmlField, it will try to map the function’s return value to something that is not there and will be unsuccessful.

  • When activating Process Approval for the K2 Designer for SharePoint via K2 Site Settings for a particular site collection an error stating "This page contains one or more errors. Fix the following before continuing: K2 server administration rights is required for user 'DOMAIN\user'." occurs. The following changes have been made to resolve this issue.
    a) All controls are disabled if the user does not have K2 Admin rights. This will mean that only a K2 Admin can change Process Approval.
    b) Not executing or validating Process Approval at Site collection level when a user is not a K2 Admin, the user might still want to change Process Participants or Designers.
    c) A red validation error message will be displayed if the user is not a K2 Admin regardless of the approval status, this informs the user of the rights needed to enable the controls, the user will however still be able to click ok and apply other settings.
  • Feature Request: Enforce the same level of permission to turn off Process Approval as to turn it on meaning K2 Admin, Local Admin, Deploy Admin is required.
  • SmartObject Management Section Label resource not found when activating K2 settings to non-English sites resulting in corrupt labels.

K2 Installation and configuration

  • An "Access Denied" error occurs when enabling Process Approval from the K2 Designer for SharePoint Configuration page in the relevant site collection’s K2 Settings page.
  • Issues are experienced when updating the Admin Hidden list (GeneralSettingsV2) with a new connection string for the K2 Designer for SharePoint and then activating to push the new connection string to the target site's internal list. The activation page does not load the connection string from the admin list but rather the current site's internal list and so activation might fail if the Database was renamed. During a reconfigure the Databases can be renamed, the installer does not re-launch the SharePoint configuration wizard to update the K2 Designer for SharePoint's connection string. This results in issues when trying to use viewflow from a SharePoint K2 webpart or an error when trying to activate all K2 Features for a particular site.
