Synchronizing error if a submission is in progress

PolicyCenter throws a ClassCastException and stops responding if you synchronize the product model from Product Designer while a submission policy transaction is in progress. To recover from this state, you must restart the PolicyCenter server.

To avoid this exception, do not synchronize the product model while a submission is in progress. Instead, navigate to a screen outside any policy transaction, such as the Account Summary screen, before synchronizing the product model.

Alternatively, enable internal debug tools by setting EnableInternalDebugTools to true in config.xml. Then, after synchronizing the product model and prior to performing any operation in PolicyCenter, press Alt+Shift+L to reload PCF files.
