How can I use multiple value in Input text field JSF - jsf

Question

In my xhtml there are 3 input field which calculate remaining day of two <p:calendar> dates. In next step I want to store calculated remaining day to MY DB.
<p:dataTable styleClass="vtable" editable="true" var="user"
editMode="cell" value="#{userBean.employeeList}">
<p:column styleClass="columntd" headerText="#{text['user.startedDate']}">
<p:calendar widgetVar="fromCal" value="#{vacationBean.vacation.beginDate}">
<p:ajax event="dateSelect" listener="#{dayDiffBean.fromSelected}"
update="diff" />
</p:calendar>
</p:column>
<p:column styleClass="columntd"
headerText="#{text['user.finishedDate']}">
<p:calendar widgetVar="toCal" value="#{vacationBean.vacation.endDate}">
<p:ajax event="dateSelect" listener="#{dayDiffBean.toSelected}"
update="diff" />
</p:calendar>
</p:column>
<p:column styleClass="columntd"
headerText="#{text['employee.remainingdays']}">
<p:inputText id="diff" styleClass="daysNumber"
value="#{dayDiffBean.diff}" />
</p:column>
</p:dataTable>
<h:commandButton styleClass="sndbutton1"
value="#{text['employee.send']}" action="#{vacationBean.addVac}"/>
I used value="#{dayDiffBean.diff} to get remaining day and now I also want to use my vacationbean to store remaingday to my db using like this : value="#{vacationBean.vacation.balanceDay}"
But I cant use 2 value in inputtext field like this:
<p:inputText value="dayDiffBean.diff" value1="vacationBean.vacation.balanceDay">
How can i solve this problem?
This is my vacation bean code:
#ManagedBean(name="vacationBean")
#ViewScoped
public class VacationBean implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Date vEndDate;
private boolean selected;
private Date vStartDate;
private Date createdDate;
private String isNobody;
Requestrelax vacation;
Employee e;
Calendar javaCalendar = null;
private short balanceDay;
#EJB
VacationLocal vacations;
#ManagedProperty(value="#{loginBean.userId}")
Integer userId;
#EJB
EmployeesLocal employees;
#PostConstruct
public void init(){
System.out.println("0");
//System.out.println("STATrtsg >> . "+ diff.getDiff());
vacation=new Requestrelax();
e=employees.getEmployee(userId);
vacation.setEmployee(e);
System.out.println("balanday is:"+balanceDay);
}
public void addVac(){
System.out.println("1");
javaCalendar = Calendar.getInstance();
Date currenDate=Calendar.getInstance().getTime();
vacation.setCreatedDate(currenDate);
vacation.setBalanceDay(balanceDay);
vacations.addEmployeeVacation(vacation);
}
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Employee getE() {
return e;
}
public void setE(Employee e) {
this.e = e;
}
public Requestrelax getVacation() {
return vacation;
}
public void setVacation(Requestrelax vacation) {
this.vacation = vacation;
}
public Date getvEndDate() {
return vEndDate;
}
public void setvEndDate(Date vEndDate) {
this.vEndDate = vEndDate;
}
public Date getvStartDate() {
return vStartDate;
}
public void setvStartDate(Date vStartDate) {
this.vStartDate = vStartDate;
}
public short getBalanceDay() {
return balanceDay;
}
public void setBalanceDay(short balanceDay) {
this.balanceDay = balanceDay;
}
public Date getCreatedDate() {
return createdDate;
}
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
public String getIsNobody() {
return isNobody;
}
public void setIsNobody(String isNobody) {
this.isNobody = isNobody;
}
}
And daydiffbean code :
#ManagedBean(name="dayDiffBean")
#SessionScoped
public class DayDiffBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private Date from;
private Date to;
private String diff="";
private final long oneDay=1000*60*60*24;
public void fromSelected(SelectEvent event){
from=(Date) event.getObject();
calDiff();
}
public void toSelected(SelectEvent event){
to=(Date) event.getObject();
calDiff();
}
public void calDiff(){
if(from==null||to==null){
diff="N/A";
return;
}
diff=(to.getTime()-from.getTime())/oneDay+"";
}
public String getDiff() {
return diff;
}
public void setDiff(String diff) {
this.diff = diff;
}
public void setFrom(Date from) {
this.from = from;
}
public Date getFrom() {
return from;
}
public Date getTo() {
return to;
}
public void setTo(Date to) {
this.to = to;
}
}

From the code, one way to add balanceDay to your vacationBean is by passing the diff string as a parameter to addVac() method (notice action in the second line):
<h:commandButton styleClass="sndbutton1" value="#{text['employee.send']}"
action="#{vacationBean.addVac(dayDiffBean.diff)}"/>
Then, for your VacationBean.addVac():
// 'diff' is now being passed in as a parameter
public void addVac(String diff) {
System.out.println("1");
javaCalendar = Calendar.getInstance();
Date currenDate=Calendar.getInstance().getTime();
vacation.setCreatedDate(currenDate);
vacation.setBalanceDay(balanceDay);
// UPDATED
// so now you can set balanceDay
setBalanceDay(Short.parseShort(diff));
vacations.addEmployeeVacation(vacation);
}
