Class ERD2WRule

java.lang.Object
  com.webobjects.directtoweb.Rule
      er.directtoweb.ERD2WRule

All Implemented Interfaces:

EOKeyValueArchiving, Serializable

public class ERD2WRule
extends com.webobjects.directtoweb.Rule

Rule class that works around two problems:

• when you have an assignment class that is not present in the classpath then the model will not load, making for very strange errors. We replace the missing class with the normal assignment class and log the error.
• when evaluating rule priorities, the default is to place rules containing pageConfiguration keys so high up that they will get preferred over rules without such a condition, but with a higher author setting. This is pretty ridiculous and leads to having to set ... AND (pageConfiguration like '*') in all the conditions.
  We place rules with a pageConfiguration so high that they will be higher than rules with the same author setting but lower than a rule with a higher setting.

In order to be usable with the D2WClient and Rule editor, we also patch the encoded dictionary so these tools find no trace of the patched rules.
