我想添加一個自定義的VF組件來在頁面塊表中顯示批處理作業的詳細信息。然而，我的組件不存在，它說：錯誤錯誤：只讀屬性'c：batchDetailsComponent.BatchJobDetails' 請幫助。如何在visualforce自定義組件中使用頁面塊表？
這是visualforce組件：
<apex:component controller="BatchOpportunityDetailsExtension">
<apex:attribute name="batchJob" type="List" assignTo="{!BatchJobDetails}" description="" />
<apex:form >
<apex:pageBlock>
<apex:pageblockTable value="{!batchJob}" var="batch">
<apex:column value="{!batch.CompletedDate}"/>
<apex:column value="{!batch.JobItemsProcessed}"/>
<apex:column value="{!batch.NumberOfErrors}"/>
</apex:pageblockTable>
</apex:pageBlock>
</apex:form>
</apex:component>
VF頁：
<apex:page standardController="Opportunity_Scheduled_Information__c"
extensions="BatchOpportunityDetailsExtension">
<c:oppScheduleComponent componentValue="{!batchJob}"/>
</apex:page>
控制器：
public class BatchOpportunityDetailsExtension {
public List<AsyncApexJob> batchJobDetails = new List<AsyncApexJob>();
public Opportunity_Scheduled_Information__c pageController {get;set;}
public BatchOpportunityDetailsExtension() {}
public BatchOpportunityDetailsExtension(ApexPages.StandardController controller) {
controller.addFields(new List<String>{'Total_Amount__c', 'Number_of_Opportunities__c'});
pageController = (Opportunity_Scheduled_Information__c)controller.getRecord();
BatchJobDetails = [ SELECT id,ApexClassID,CompletedDate,JobType,JobItemsProcessed,NumberOfErrors,MethodName,Status,ExtendedStatus,TotalJobItems FROM AsyncApexJob WHERE ApexClassId='01p7F000000bKIlQAM' LIMIT 50] ;
}
public List<AsyncApexJob> getBatchJobDetails()
{
return BatchJobDetails ;
}
}
