我在对话框中使用一个表单来编辑一些数据，我使用 setPropertyActionListener 标签从dataTable获取此数据，我的表单正确显示所有字段，但是当我更改一些数据并关闭时对话框并重新打开它（没有调换）表单保留最新数据并忽略来自 setPropertyActionListener
的内容这是我用来打开对话框的代码
<p:menuButton value="Actions">
<p:menuitem resetValues="true" value="Update"
icon="fa fa-edit" process="@this"
actionListener="#{myMB.resetSelectedEntite(a)}"
update="formUpdateAff:displayEditionAff"
oncomplete="PF('affUpdateDialogWidget').show()">
<f:setPropertyActionListener
target="#{myMB.selectedAffectation}" value="#{a}" />
<f:actionListener
type="com.dummy.AffActionListener" />
</p:menuitem>
对话框代码：
