new added element to list will update all current elements of the list while using session bean

[Suresh Khant]

Hi All,

I am creating a small form in which the user is allowed to enter his multiple phone nos which will be stored in a list , unfortunately whenever i tried to add more then one phone to the list , it will take both the item as the last entered number

example

addPhoneNo Form
User Phone : 1234


again open and add another phone number
User Phone : 4321


now the contents of userPhoneNosList is
phone : 4321
phone : 4321




part of addPhoneNo.xhmtl

<h:form>

		<table>
			<tr>
				<td>User Phone : </td>
				<td><h:inputText value="#{userDetailsBean.newUserPhoneNo}" /></td>
			</tr>
			<tr>
				<td><h:commandButton value="Submit" action="listUserDetails"
					actionListener="#{userDetailsBean.addUserPhoneNo}" /></td>

			</tr>
		</table>
	</h:form>

part of faces-config.xml

<managed-bean>
  <managed-bean-name>newUserPhoneNo</managed-bean-name>
  <managed-bean-class>java.lang.String</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>
  
  <managed-bean>
  <managed-bean-name>userDetailsBean</managed-bean-name>
  <managed-bean-class>com.example.UserDetailsBean</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
   <managed-property>
   <property-name>newUserPhoneNo</property-name>
   <property-class>java.lang.String</property-class>
   <value>#{newUserPhoneNo}</value>
  </managed-property>
 </managed-bean>

UserDetailsBean.java

import java.awt.event.ActionEvent;
import java.util.ArrayList;
import java.util.List;
public class UserDetailsBean {

	private String newUserPhoneNo;
	private List<String> userPhoneNosList;

	public String getNewUserPhoneNo() {
		return newUserPhoneNo;
	}

	public void setNewUserPhoneNo(String newUserPhoneNo) {
		this.newUserPhoneNo = newUserPhoneNo;
	}

	public List<String> getUserPhoneNosList() {
		return userPhoneNosList;
	}

	public void setUserPhoneNosList(List<String> userPhoneNosList) {
		this.userPhoneNosList = userPhoneNosList;
	}

	public void addUserPhoneNo(ActionEvent ae) {

		if (this.newUserPhoneNo != null) {
			if (this.userPhoneNosList == null)
				this.userPhoneNosList = new ArrayList<String>();

			this.userPhoneNosList.add(this.newUserPhoneNo);
			for (String phone : this.userPhoneNosList) {
				System.out.println("phone : " + phone);
			}

		}

	}
}

Not sure.. but can you remove this configuration..

  <managed-bean>
  <managed-bean-name>newUserPhoneNo</managed-bean-name>
  <managed-bean-class>java.lang.String</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
  </managed-bean>

You're saving something in the session that is a string.. although I am not sure enough regarding your business case..

Have you tried of debugging the method which uses to add phone numbers in the List? Suspect on setNewUserPhoneno too.
