Struts2 - Nested Iterators

Hey Googler,

Unable to find out a more versatile solution of having a nested iterator in Struts2. Want to know the naming convention to be used in JSP, in case of nested iterator so that it can be submitted through a form ?Here comes the solution.

This is how the JSP code will look like:

        <s:form action="saveaction" >

            <s:iterator value="lstBean" id="lstBean" status="outerStat">

                <s:textfield value="%{name}" name="lstBean[%{#outerStat.index}].name"/>

                <s:textfield value="%{amt}" name="lstBean[%{#outerStat.index}].amt"/>

                <s:textfield value="%{id}" name="lstBean[%{#outerStat.index}].id"/>

                <s:iterator value="%{lstString}" status="myStat">

                    <s:textfield name="lstBean[%{#outerStat.index}].lstString[%{#myStat.index}]"/>

                </s:iterator>

            </s:iterator>

            <s:submit value="Click me to submit lstBean"/>

        </s:form>

Following is the bean(XBean) whose List is used in the JSP:

public class XBean

{

    private ArrayList<String> lstString=new ArrayList<String>();

    private String name;

    private Double amt;

    private Integer id;

      //Getters and setters of fields

}

Now you can simply have a field lstBean with setters in your submitting action (saveaction) and hey you are done!!!!
