The Working Memory view display the objects in working memory for the RetePlus execution mode. Use it with the Agenda view to easily check whether the rules behave as expected.
The view can display the value and type of the various fields of the object. From that view, you can dynamically inspect the objects as they affect the rules. This is important to check whether a rule behaves correctly. For example, you can easily check the behavior of the rules currently in the agenda that use a specific value.
