In case you didn't figure this out already, the method signature of
the action method does not take a parameter.
I believe you want to use the action="#{quantityBean.putOneBack}" in
your jsp page and
in your backing bean, have a method
public String putOneBack() {
System./out/.println("QuantityBean.putOneBack()");
quantity--;
return "success";
}
If you are staying on the same page, you can return null.
There was confusion because there is also an actionListener attribute
that can be used to just listen for events and not change the viewId.
If you use the actionListener attribute,
then the signature of the listener method would be return void and
take an ActionEvent parameter.
