我有一个selectOneMenu,用于更改辅助bean中的值,并根据该值显示或不显示另一个组件。我想要的是在selectOneMenu更改支持bean中的值后更新该特定组件
Sub DeleteRowsThatLookEmpty()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Dim Rng As Range, ix As Long
Set Rng = Intersect(Range("A:A"), ActiveSheet.UsedRange) 'You can specify the sheet you want and change the column
For ix = Rng.Count To 1 Step -1
If Trim(Replace(Rng.Item(ix).Text, Chr(160), Chr(32))) = "" Then
Rng.Item(ix).EntireRow.Delete
End If
Next
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub
支持bean中的值发生了变化,但未更新。

这应该有效
<h:selectOneMenu value="#{backingBean.id.value}" >
<f:selectItem itemLabel="Choose" itemValue="0"/>
<f:selectItems value="#{backingBean.idList}"
var="id" itemLabel="#{id.name}" itemValue="#{id.value}" />
<p:ajax listener="#{backingBean.changeId}" process="@this" update="userMenuWrapper"/>
</h:selectOneMenu>
<p:outputPanel id="userMenuWrapper">
<p:menu id="userMenu" rendered="#{backingBean.id.value != 0}"/>
</p:outputPanel>
