<rich:calendar>不接受java.util.Calendar

Question

我正在尝试使用rich:calendar，当日期属性selectedDate和currentDate是Date类型时，它可以工作。当我使用Calendar时，它不起作用。

当我提交一份表格时，它会报告：

SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/PORTAL] threw exception [javax.el.ELException: /test.xhtml @58,36 value="#{bean.calendar.selectedDate}": Cannot convert 24.6.11 0:00 of type class java.util.Date to class java.util.Calendar] with root cause
javax.el.ELException: /test.xhtml @58,36 value="#{bean.calendar.selectedDate}": Cannot convert 24.6.11 0:00 of type class java.util.Date to class java.util.Calendar

我的XHTML

<rich:calendar 
  mode="ajax" id="calendar"
  value="#{bean.calendar.selectedDate}"  
  locale="#{calendarBean.locale}"  
  datePattern="#{calendarBean.pattern}"                        
  required="true">                   
</rich:calendar>

和日历bean

@ManagedBean
public class CalendarBean
{    
  private Calendar currentDate;  
  private Calendar selectedDate;

  public Calendar getCurrentDate() {  
    return currentDate;  
  }  
  public void setCurrentDate(Calendar currentDate) {  
    this.currentDate = currentDate;  
  } 
  public Calendar getSelectedDate() { 
    return selectedDate;  
  }  
  public void setSelectedDate(Calendar selectedDate) {  
    this.selectedDate = selectedDate;  
  }

我做错什么了？

Calendar类具有一个time属性，该属性表示一个java.util.Date，包含一个吸气剂和塞特。好好利用它。

value="#{bean.calendar.selectedDate.time}"
