Known Issues

A list of some of the current known issues that you may encounter when using K2 smartforms 1.0.6 is available in the K2 smartforms 1.0.6 (4.12165.1625.0) Known Issues List.

Important Considerations

  1. K2 smartforms 1.0.6 has a dependency on K2 blackpearl 4.6.7.
  2. Claims configuration – The claims configuration has been moved from the web.config file to the K2 database. For clean installations the K2 Setup manager will configure your environment to run with claims and will enter the required configuration settings in the new database tables. When upgrading, if claims were previously configured, the configuration settings will remain in the web.config and will also be entered in the new database tables.
  3. HTTPS/HTTP - During the installation of K2 smartforms all K2 sites will be certified and configured to run as HTTPS or as HTTP. During a standalone installation the certificate is automatically created by K2. In a custom installation the certificate can either be created by K2 or you can select an existing certificate.
  4. .NET Framework 4.5 required- The .NET Framework 4.5 is now required for the Design Time and Runtime sites. Ensure that the .NET Framework 4.5 is installed before installing K2 smartforms 1.0.6. The .NET Framework 4.5 installer can be located at:
  5. Application Pool .NET Framework change - The SmartForms’ Application Pool must run on .NET Framework 4.5. If you have an existing SmartForms Application Pool running on the .NET Framework 3.5 (displayed as .NET Framework v2.0.50727 in IIS) and this application pool is used for other applications as well, a new application pool is required for K2 smartforms 1.0.6.  If you have an existing application pool running on the .NET Framework 3.5 that is only used for K2 smartforms, this application pool needs to be configured to run on the .NET Framework 4.5 (displayed as .NET Framework v4.0.30319 in IIS). Refer to http://msdn.microsoft.com/en-us/library/hh925568.aspx to know which .NET Framework is installed in your environment.
  6. Application Pool Integrated mode change  - To enhance the performance of SmartForms, the Application Pool's Managed pipeline mode must be set to Integrated where previously it was set to Classic for both Design Time and Runtime. However, if other applications are dependent on the same Application Pool, K2 will not change the mode but will rather inform the user that a new Application Pool needs to be created. The K2 blackpearl Application Pool count can no longer be used as it must be set to Classic mode.

Behavioral Change

  1. The Silverlight controls (File Attachment with Progress and Image Attachment with Progress) have been removed and are no longer available in the controls tab. The attachment controls’ functionality has been enhanced to show a pie chart as the upload progresses. When upgrading to SmartForms 1.0.6 or deploying a package any existing Silverlight controls will be changed to attachment controls.
