Resolved issues

The following table lists all resolved issues for PI AF Client 2023.

Known issues

The following items are known issues:

• If you are using PI Asset Framework to store complex types in AFValue and ExtendedProperties, some functionality may be lost initially on upgrade. This can be remediated by setting enableBinaryFormatter to ‘True’ in the AFSDK.config on PI Clients.

  Note: The 'enableBinaryFormatter' setting is discouraged.

• In Asset Framework, the Get Attribute Values method for elements (AFElement.GetAttributeValues) and event frames (AFEventFrame.GetAttributeValues) allow an optional WindowsIdentity/ClaimsIdentity to be passed in so that a service, using a trusted subsystem model, can evaluate access for the specified user identity. However, if the service is not running with PI System administration rights, the identity parameters are ignored, and the attributes and data are returned with the access rights of the caller (the trusted subsystem). This may result in granting Read Data privilege to the attributes to the end-user.

  The work around is to run the trusted subsystem service with admin rights on the PI System. This issue only affects applications that are trying to impersonate calls to users, such as the PI SQL Data Access Server (Real-Time Query Processing Engine).
