编辑后更新数据表中的列时遇到问题。 我使用对话框来编辑您想要的数据。您正在保存数据库中的所有内容,即问题 重新更新表格,字段正在使用新值更新, 只有一个没有更新,只是对话框中的selectOneMenu。 未更新的字段来自Lotação,其余字段正在运行。

非常感谢你。

您必须在命令按钮或ajax调用中使用update属性。
<f:ajax execute="@all" update=":form:tab" render=":form:tab"/>
或
{{1}}
确保在支持的bean
中更新对象答案 1 :(得分:0)
在您的对话框中
<h:selectOneMenu id="lotacoes" value="#{impressoraMB.impressora.id_Lotacoes}" effect="fold"
required="true" immediate="true" style="width:100%">
,而您的DataTable使用
<p:column id="lotacao" headerText="Lotação" filterBy="#{impressora.nome}"
filterMatchMode="contains" style="width:110px">
<h:outputLabel value="#{impressora.nome}"/>
</p:column>
如果更改两个不同.xhtml文件之一的值,则应该具有预期结果
