我有一个使用primefaces的DataTable复合组件。
<cc:interface>
<cc:attribute name="amountToAllocate" />
<cc:attribute name="transactionsToAllocate" />
<cc:attribute name="selectedTransactions" />
<cc:attribute name="allocateAutoUpdateId" />
<cc:attribute name="amountAllocated" />
<cc:attribute name="allocationRemaining" />
<cc:attribute name="rowSelectUpdateId" />
<cc:attribute name="allocateAutoListener"
method-signature="void action()" />
<cc:attribute name="toggleSelectListener"
method-signature="void action(org.primefaces.event.ToggleSelectEvent)" />
<cc:attribute name="selectRowListener"
method-signature="void action(org.primefaces.event.SelectEvent)" />
<cc:attribute name="unselectRowListener"
method-signature="void action(org.primefaces.event.UnselectEvent)" />
</cc:interface>
<cc:implementation>
<p:dataTable value="#{cc.attrs.transactionsToAllocate}"
var="transaction"
selection="#{cc.attrs.selectedTransactions}"
rowKey="#{transaction.transactionId}" >
<p:ajax event="toggleSelect"
listener="#{cc.attrs.toggleSelectListener}"
update="#{cc.attrs.rowSelectUpdateId}" />
<p:ajax event="rowSelectCheckbox"
listener="#{cc.attrs.selectRowListener}"
update="#{cc.attrs.rowSelectUpdateId}" />
<p:ajax event="rowUnselectCheckbox"
listener="#{cc.attrs.unselectRowListener}"
update="#{cc.attrs.rowSelectUpdateId}" />
<p:column selectionMode="multiple"
style="width:16px;text-align:center"/>
<p:column headerText="Reference">
#{transaction.reference}
</p:column>
<p:column headerText="Invoice Date">
<h:outputText value="#{transaction.transactionDate}">
<f:convertDateTime pattern="dd/MM/yy" />
</h:outputText>
</p:column>
</p:dataTable>
</cc:implementation>
它的实现在这里：------------------------
<h:panelGroup id="alloc">
<ezcomp:transactionAllocation amountToAllocate="#{apCreditNoteTransactionBean.transaction.value}"
transactionsToAllocate="#{apCreditNoteTransactionBean.transactionAllocationInvoiceData.unallocatedTransactions}"
selectedTransactions="#{apCreditNoteTransactionBean.transactionAllocationInvoiceData.selectedUnallocatedTransactions}"
allocateAutoListener="#{apCreditNoteTransactionBean.autoAllocateTransactionToSelectedTransaction}"
allocateAutoUpdateId=":#{p:component('alloc')}"
amountAllocated="#{apCreditNoteTransactionBean.transactionAllocationInvoiceData.amountAllocated}"
allocationRemaining="#{apCreditNoteTransactionBean.transaction.value-apCreditNoteTransactionBean.transactionAllocationInvoiceData.amountAllocated}"
toggleSelectListener="#{apCreditNoteTransactionBean.onToggleSelect}"
selectRowListener="#{apCreditNoteTransactionBean.onRowSelect}" unselectRowListener="#{apCreditNoteTransactionBean.onRowUnSelect}"
rowSelectUpdateId=":#{p:component('alloc')}"
/>
</h:panelGroup>
问题是当取消选择它引发错误的行时：
引起：javax.el.PropertyNotFoundException：Property＆＃39; onRowUnSelect＆＃39;在类型beans.APCreditNoteTransactionBean
上找不到我在bean中定义了方法：
public void onRowUnSelect(UnselectEvent event) {
}
但如果rowUnselectCheckbox监听器直接从托管bean分配为
，则可以正常工作<p:ajax event="rowUnselectCheckbox" listener="#{apCreditNoteTransactionBean.onRowUnSelect}" update="#{cc.attrs.rowSelectUpdateId}" />
但是其他事件：toggleSelect和rowSelectCheckBox导致以下错误：
java.lang.ArrayIndexOutOfBoundsException: 0
