Question

我想在bean中获取selectOneMenu值但是值没有得到正确.SubstituteHoliday是一个布尔变量。但是，我只对yes和no selectItem都得到假。我可以为selectOneMenu得到适当的值。基于selectOneMenu价值如果是，则意味着我想要更换日期单位...

提前致谢...

       <p:dataTable id="manager" var="item" value="#{employeeWorkingHolidayBean.userListTwo}"
                    paginator="true" rows="10"
                    paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                    rowsPerPageTemplate="2,5,10,15" 
                    editable="true" editMode="cell" style="width:600px;" styleClass="postformatte"
                    emptyMessage="No Employee Working Holiday Details found with given criteria" resizableColumns="true" > 

                <p:ajax event="cellEdit" listener="#{employeeWorkingHolidayBean.onCellEdit}"
                    update=":form:growl"/>
                   <p:ajax event="colResize" update=":form:growl" listener="#{employeeWorkingHolidayBean.onResize}" />  


                <p:column headerText="Employee Id" width="90" >
                        <h:outputText value="#{item.employeeId}" />
                </p:column>

                <p:column headerText="Is Substitute Holiday">  
                <p:cellEditor>  
                <f:facet name="output"><h:outputText value="#{item.substituteHoliday}" /></f:facet>  
                <f:facet name="input">  
                <h:selectOneMenu value="#{item.substituteHoliday}" style="width:100%">  
                        <f:selectItems value="#{employeeWorkingHolidayBean.subsholiday}"/>
                        <p:ajax event="change" update="subdate"/>
                </h:selectOneMenu>

                <p:column headerText="Substitute Date" >  
                <p:cellEditor>  
                <f:facet name="output"><p:calendar pattern="dd-MM-yyyy" yearRange="#{c-100}" navigator="true" showButtonPanel="true" value="#{item.substituteDate}"/></f:facet>

                </p:cellEditor>  
                </p:column>

      </p:dataTable>

豆：

      private Boolean isdiableEffectdate;
      public Boolean getIsdiableEffectdate() {
             return isdiableEffectdate;
         }

      public void setIsdiableEffectdate(Boolean isdiableEffectdate) {
        this.isdiableEffectdate = isdiableEffectdate;
        }

      public void onCellEdit(CellEditEvent event)
    {   

        Object oldValue = event.getOldValue();  
        Object newValue = event.getNewValue();  
        logger.info("Old value"+oldValue);
        logger.info("New value"+newValue);
        if(newValue.equals(true))
        {
            logger.info("enter if true");
            isdiableEffectdate=true;
        }
        else
        {
            logger.info("enter if false");
            isdiableEffectdate=false;
        }
        if(newValue != null && !newValue.equals(oldValue)) 
        {  
            FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Cell Changed", "Old: " + oldValue + ", New:" + newValue);  
            FacesContext.getCurrentInstance().addMessage(null, msg);  

        }  

    }

为select as，

添加一个VCE（Value changeListener Event）

<h:selectOneMenu value="#{item.substituteHoliday}"
    valueChangeListener="#{item.selectHolidayValueChangeListner}" 
    style="width:100%">
    <f:selectItems value="#{employeeWorkingHolidayBean.subsholiday}"/>
    <p:ajax event="change" update="subdate"/>
</h:selectOneMenu>

并且在valueChangeListener方法中将新值赋给全局变量as，

public void selectHolidayValueChangeListner(ValueChangeEvent vce) {
    if (vce.getNewValue() != null) {
        substituteHoliday = vce.getNewValue().toString(); 
    }
}

现在，在你的ajax方法中获取substituteHoliday的值并执行所需的任何操作。
