Clear the Tomcat Server Cache
When the following events occur, you should clear the server cache to ensure new information is properly displayed in .NET UI:

Note: It is recommended to complete installations in a new directory.
After you rebuild the .NET UI
After you attach or detach a lookup from any field
To clear the cache, follow these steps:
1 Shut down Tomcat.
2 Go to the TomcatInstallDir/webapps/qaduiConfig/cache directory.
3 Delete all subdirectories and files located in this directory.
4 If you are installing a new .NET UI release, complete the installation.
