I have a form in spring mvc 2 having command class "Class1"
I want to bind Class3 elements with an input field in this form. Below are my classes.
I am iterating/binding over Class2 elements in JSP other than map like this
<c:forEach var="item" items="${class1.class2List}" varStatus="itemsRow">
<form:input path="class2List[${itemsRow.index}].anyElement2" />
..........
</c:forEach>
My Classes looks like
Class1
List<Class2> class2List;
String anyElement1;
Class2
Map<String, Class3> class2Map;
String anyElement2;
Class3
Map<String, Class3> class3Map;
String nameToGet;
String anyElement3;
How can I bind anyElement3
inside class3Map
. Is it possible?
