I ended up overriding the 'evaluateExtraParams()' method and performing the
exact same logic that is in the ListUIBean.evaluateExtraParams() to set a new
parameter called 'listCopy' to use in the extra iterator.
Code:
@Override
public void evaluateExtraParams() {
super.evaluateExtraParams();
//This is the same logic as in 'evaluateExtraParams()' but I need a copy of
the 'list'.
Object value = null;
if (list == null) {
list = parameters.get("list");
}
if (list instanceof String) {
value = findValue((String) list);
} else if (list instanceof Collection) {
value = list;
} else if (MakeIterator.isIterable(list)) {
value = MakeIterator.convert(list);
}
if (value == null) {
if (throwExceptionOnNullValueAttribute) {
// will throw an exception if not found
value = findValue((list == null) ? (String) list : list.toString(),
"list",
"The requested list key '" + list + "' could not be resolved as
a collection/array/map/enumeration/iterator"+
" type. " +
"Example: people or people.{name}");
} else {
// ww-1010, allows value with null value to be compatible with ww
// 2.1.7 behavior
value = findValue((list == null)?(String) list:list.toString());
}
}
if (value instanceof Collection) {
addParameter("listCopy", value);
} else {
addParameter("listCopy", MakeIterator.convert(value));
}
}

Use <#assign> and create a copy?
