我有一个带有面板和两个dataTable的表单。下面的代码删除了大部分列,以便更容易理解。
<h:form id="invoiceLookUp">
<p:panel>
<f:facet name="header">
<p:column style="font-weight: bold;">
Invoice Selection Criteria
</p:column>
</f:facet>
<h:outputText value="Seq ID"/>
<p:inputText
id="invoice_header_seq_id" styleClass="field" size="10"
value="#{invoiceBean.invoice_header_seq_id}"
/>
<p:commandButton
update="invoicesTable" value="Look Up"
action="#{invoiceBean.addInvoices()}"
/>
</p:panel>
<p:dataTable
id="invoicesTable" var="invoice" rows="15" lazy="true" selectionMode="single"
value="#{invoiceBean.invoiceList}"
rowKey="#{invoice.invoiceHeader.invoiceHeaderSeqId}"
selection="#{invoiceBean.selectedInvoice}"
>
<p:ajax event="rowSelect" update=":invoiceLookUp:invoiceLinesTable"/>
<f:facet name="header"><h:outputText value="Invoice Headers" /></f:facet>
<p:column sortBy="#{invoice.invoiceHeader.invoiceHeaderSeqId}" id="invoiceSeqId">
<f:facet name="header">
<h:outputText value="Seq ID" title="Invoice Header Seq ID"/>
</f:facet>
<h:outputText value="#{invoice.invoiceHeader.invoiceHeaderSeqId}" />
</p:column>
</p:dataTable>
<p:dataTable
id="invoiceLinesTable" var="invoiceLine" rows="15" lazy="true" selectionMode="single"
value="#{invoiceBean.selectedInvoice.invoiceLines}"
rowKey="#{invoiceLine.invoiceLineSeqId}"
selection="#{invoiceBean.selectedInvoiceLine}"
>
<f:facet name="header"><h:outputText value="Invoice Lines" /></f:facet>
<p:column sortBy="#{invoiceLine.invoiceLineSeqId}" id="invoiceLineSeqId">
<f:facet name="header"><h:outputText value="Line Seq ID"/></f:facet>
<h:outputText value="#{invoiceLine.invoiceLineSeqId}"/>
</p:column>
</p:dataTable>
</h:form>
输入Seq ID然后单击“查找”时,表格将按预期填充。当我在invoicesTable中选择一行时,出现以下错误: javax.faces.FacesException:找不到标识符为“:invoiceLookUp:invoiceLinesTable”的组件,该组件引自“form:invoiceLookUp:invoicesTable”。
谁能告诉我我做错了什么?
