Ok. I read the OGNL spec and it looks like the way of using maps etc. is subtley different from Struts1. My JSP now looks like
<s:textfield name="attribute[#currentField.fieldname]"/> and the associated Action class has methods public void setAttribute(String key, Object value) public Object getAttribute(String key) The setAttribute method is still not being called (again, I have checked with debug print statements), but this time in the catalina log I get the following excepion messages along with a large stack trace --snip-- Apr 18, 2007 9:57:01 AM com.opensymphony.xwork2.util.InstantiatingNullHandler nullPropertyValue SEVERE: Could not create and/or set value back on to object ognl.NoSuchPropertyException: com.csc.event.delivery.controller.EventOverviewController.attribute [java.lang.IllegalAccessException: Class ognl.OgnlRuntime can not access a member of class com.csc.event.delivery.controller.EventOverviewController with modifiers "private"] --snip-- It looks like it wants the actual attribute member to be public, but I really dont want to do that...
