Struts2: Updating the values of a “List Of Objects” inside a Map

by

According to your latest update. If you are using TreeMap Struts2 cannot correctly determine type of elements inside it. Change declaration of testTreeMap from TreeMap to Map.

private Map<String,ObjectCList> testTreeMap = new TreeMap<String,ObjectCList>();

Or annotate testTreeMap with com.opensymphony.xwork2.util.Element annotation to tell Struts2 what type are elements inside map.

@Element(value = ObjectCList.class)
private TreeMap<String,ObjectCList> testTreeMap = new TreeMap<String,ObjectCList>();
