Hello,

When i click on button ,it does not enter to method ,and  Seam throws this exception:
Exception during request processing: Caused by javax.servlet.ServletException with message: "value of context variable is not an instance of the component bound to the context variable: universityResourceReserveController. If you are using hot deploy, you may have attempted to hot deploy a session or application-scoped component definition while using an old instance in the session."

In my JSF page i have :
<h:commandButton  action="#{universityResourceReserveController.reserveResource}"  value="reserve">
</h:commandButton>

and this is my controller :
--------------------------------------------------------------------
@Name("universityResourceReserveController")
public class UniversityResourceReserveController extends
        EntityController<UniversityResources> {
public String reserveResource() {
        current = universityResourcesDAO.findById(current.getId());
        try {
            for (int i = 0; i < days.size(); i++) {
                Day day = days.get(i);
                List<Hour> hours = day.getHours();
                for (Hour hour : hours) {
                    if (hour.getBoolean1().equals(Boolean.TRUE)) {
                             Schedule schedule = scheduleDAO
                                .findScheduleByDateANDByDayNameANDByHour(day
                                        .getDate(), day.getDayNumber(), hour
                                        .getStartTime(), hour.getEndTime());
                        current.getSchedules().add(schedule);
                    }
                }
            }
            universityResourcesDAO.save(current);
            return "succ";
        } catch (Exception e) {
            return "fails";
        }
    }
}
--------------------------------------------------------------------
When i click on button ,it does not enter to method ,and  Seam throws this exception:
