It would be great if struts would support enum concepts.
Apparently, http://jakarta.apache.org/commons/lang/api/org/apache/commons/lang/enums/Enum.html is partially supported as per http://marc.theaimsgroup.com/?l=struts-dev&m=98960078911784&w=2 for example in <html:options>
However, it would very useful to also support http://java.sun.com/j2se/1.5.0/docs/guide/language/enums.html in a way that the programmer no longer needs to think of strings.
Also, "Struts Action 1" users may be forced to stay on jdk1.4, but would like to already use a design pattern the will require minimum refactoring when migrating to 5.0. Does anybody have any experience in this sector (or could http://retroweaver.sourceforge.net/ be a good source of inspiration even though it does exactly the opposite...)
My vision is that
<logic:iterate>, <logic:equal>, <html:options>, <html:radio>, ... could work directly on 5.0 enum
Also, the strings to which enum will be mapped should carefully kept as short as possible, because GET URLs may end-up in email messages that sometimes force-hyphenate them, i.e destroy them for avaerage users.
Lastly, it would be great if the chosen approach somehow could also be leveraged for persistence frameworks such as http://www.hibernate.org/288.html
