All Implemented Interfaces:

org.apache.commons.chain.Command<ActionContext>, ActionCommand

public class CacheMessages
extends ActionCommandBase

Copies any ActionMessages from the request to the session if a redirecting forward is selected and the messages were not accessed. This allows messages to be retained across a redirect, and then later released by the RemoveCachedMessages command. The most common use case for this command is when the validator or exception handler places messages in the request.

Struts 1.4.0
