primefaces spinner not able to save value to use in another class - jsf

Question

Bit of a strange one, i got a spinner working,
<p:spinner min="1" max="1000" value="#{printerSettings.t}" size ="1">
<p:ajax update="NewTime"/>
</p:spinner>
<h:outputText value="#{printerSettings.getNewTime()}" id="NewTime"/>
this goes up by 1 each time and the ajax is working fine
this is the server side java code :
public int getT() {
return (t);
}
public void setT(int t) {
this.t = t;
}
what i want to know is how can i save the final value of t, as i want to use this value in another class, i have tried
t = ((new PrinterSettings().getT()) * 60);
in the class i want to use t but i always get 1 and not the value that is left from the spinner
how can i solve this issue
EDIT:
#ManagedBean
#RequestScoped
public class PrintInTen {
private int t;
public void tValue(int t) {
this.t = t;
System.out.println("My t value : " + t);
}
public void countDown() {
is the bean that i am trying to get t to be sent to
i have create a button to send it to above :
<p:commandButton actionListener="#{printInTen.setTValue(printerSettings.t)}" value="Set Val" />
but i get an error : unknown property setTvalue
am i on the right lines here ? and how can i solve that error
get this error

Answer 1

If you are creating a new PrinterSettings, you will alwasy be getting 1.
You would have to find a way to inject your PrinterSettings within the new class you want to use it in.
It would look as such :
#ManagedProperty("#{PrinterSettings"})
private PrinterSettings printerSettings;
Then you could use that to get the value you need.
ALSO Make sure you are in the proper scope.
OR
You could onsubmit or the click of a button set the value of your spinner to your new bean.
<p:button actionListener="#{otherBean.tValue(printerSettings.t)}" value="Set Val" />
Edit
Following the edit to the question, your bean would look like this :
#ManagedBean
#RequestScoped
public class PrintInTen {
private int t;
public void tValue(int t) {
this.t = t;
System.out.println("My t value : " + t);
}
...
}
not tested, but should work
