解决方案
A fix is now available to correct this problem in 1.5i Service Pack 2:
CAUTION: This FTP Update is intended as a fast response for the issue mentioned only. The risk inherent in this fast response is that there is not enough time or resources available for the full regression testing that is done for the Service Pack Updates and there is a higher risk of introducing new problems. It is recommended that customers always install the latest Service Pack Update, but only install FTP Updates when needed to resolve specific issues.
This file is compatible with 1.5i Service Pack 2 only and should be installed after the 1.5i SP2 Implementation Tools Update has been installed.
