All Implemented Interfaces:

public class ReplacementSessionFormCache
extends SimpleSessionFormCache

This Cache emulates the way that the AbstractFormController handled form caching. The org.shept.org.springframework.web.servlet.mvc.classic.AbstractFormController handled form caching by saving just the current form in the session. The form was removed from the session when obtaining the command object. When the workflow through the Controller completed, org.shept.org.springframework.web.servlet.mvc.classic.AbstractFormController#showForm exposed the form again to the session. This was a somewhat inflexible design. It makes sparse use of session memory but this was hardcoded and it didn't allow for a configurable stategy where session memory resources are not a bottleneck.
