我正在尝试创建一个具有可编辑和动态列和行的数据表。但是当我尝试处理表格时，我输入的值没有被处理（它们都为空）。
我将在下面发布我的代码，希望有人可以帮助我弄清楚发生了什么。
（我发布的代码只是整个代码的一部分，但它已经不起作用了）
我正在使用绑定属性创建表：
<p:panelGrid columns="2">
<p:panelGrid columns="1">
<h:outputText value="Fornecedor" styleClass="headerColumn" />
<p:panelGrid columns="2" columnClasses="inputBotao">
<p:selectOneMenu value="#{orcamentoAction.idFornecedor}"
id="selForn" filter="true" filterMatchMode="startsWith">
<f:selectItem itemLabel=" - " itemValue="#{null}" />
<f:selectItems value="#{orcamentoAction.fornecedores}" var="f"
itemLabel="#{f.nomeForn}" itemValue="#{f.idForn}" />
<p:ajax event="change" />
</p:selectOneMenu>
<p:commandButton action="#{orcamentoAction.addFornecedor}"
icon="ui-icon-plus" process=":formEx:pfTable @this"
update=":formEx:pfTable :formEx:selForn">
</p:commandButton>
</p:panelGrid>
</p:panelGrid>
<p:panelGrid columns="1">
<h:outputText value="Produto" styleClass="headerColumn" />
<p:panelGrid columns="2" columnClasses="inputBotao">
<p:selectOneMenu value="#{orcamentoAction.idProduto}"
id="selProd" filter="true" filterMatchMode="startsWith">
<f:selectItem itemLabel=" - " itemValue="#{null}" />
<f:selectItems value="#{orcamentoAction.produtos}" var="p"
itemLabel="#{p.nomeProd}" itemValue="#{p.idProd}" />
<p:ajax event="change" />
</p:selectOneMenu>
<p:commandButton action="#{orcamentoAction.addProduto}"
icon="ui-icon-plus" process=":formEx:pfTable @this"
update=":formEx:pfTable :formEx:selProd">
</p:commandButton>
</p:panelGrid>
</p:panelGrid>
</p:panelGrid>
<p:dataTable id="pfTable" binding="#{orcamentoAction.dataTable}" />
