I am trying to assign value for empList variable employeeAttdList value attendance and dt from jsp page
My pojo classes
public class Employee implements java.io.Serializable {
private Long id;
private List employeeAttdList = new ArrayList();
//getter and setter
}
public class EmployeeAttd implements java.io.Serializable {
private Long id;
private Employee employee;
private String attendance;
private Date dt;
}
In jsp page I am trying to assigne value for attendance and dt
<s:iterator value="empList" var="elst" status="st">
<tr><td width="10%"><s:property value="%{#st.index+1}"/></td>
<td width="70%">
<s:hidden name="empList[%{#st.index}].id" cssClass="form-control" id="id" value="%{id}"/>
<label><s:property value="name"/></label>
</td>
<td width="20%">
<s:textfield name="empList[%{#st.index}].employeeAttdList[0].attendance" cssClass="attd" id="attendance[%{#st.index}]" value="%{attendance}" cssStyle="width:50px"/>
<s:hidden name="empList[%{#st.index}].employeeAttdList[0].dt" cssClass="form-control dta" id="dt[%{#st.index}]" value="1/1/1"/>
</td>
</tr>
</s:iterator>
In action
public class EmployeeAction extends ActionSupport implements ModelDriven<Employee> {
Employee e = new Employee();
List<Employee> empList = new ArrayList<Employee>();
//getter and setter
public String insertAtted() {
System.out.println("Size is " + getEmpList().size());
for (Employee ee : getEmpList()) {
ee.setClient(lc.getClient());
System.out.println("id " + ee.getId() + ", ClientId " + ee.getClient().getId());
System.out.println(" Attd list "+ee.getEmployeeAttdList());
for (EmployeeAttd ea : (ArrayList<EmployeeAttd>) ee.getEmployeeAttdList()) {
System.out.println("--------Employee Attd in -------");
ea.setClient(lc.getClient());
ea.setDt(null);
System.out.println("att " + ea.getAttendance() + " dt " + ea.getDt() + " " + ea.getClient().getId());
}
}
return SUCCESS;
}
}
