的 ModemController

Question

VisualForce 页面没有显示记录列表 - 标题说明了一切。

如何让 VF 页面显示其显然正在计算的记录（因为它显示 1-15 7549 记录）。

看起来像这样：

但是，这就是我们想要的样子（我们目前正在使用的那个！）：

http://i.imgur.com/uwXOsHS.png - ＆＃39; 调制解调器＆＃39;页面（我把一些字段涂黑了，因为我们工作的公司可能不希望披露这些信息）

我的团队正在开发salesforce.com应用程序，我们有一个对象＆＃39; 调制解调器＆＃39;，其中包含大约 7,500 记录。< / p>

的 ModemController

我们已经创建了一个自定义控制器 ModemController ：

public class ModemController {

public apexpages.standardsetcontroller con {get;set;}
public Integer noOfRecords{get; set;}
public Integer size{get; set;}
public Modem__c modems {get; set;}

public List<Modem__c> AllSearchModems
{
    get
    {
        if (con!= null)
            return (List<Modem__c>)con.getRecords();
        else
            return null;
    }
    set;
}

public ModemController() {
    AllSearchModems = new List<Modem__c>();
    modems = new Modem__c();

    String Name = ApexPages.currentPage().getParameters().get('Name');
    List<Modem__c> modems = [SELECT Name FROM Modem__c WHERE ID= :Name];
}

public PageReference save()
{
    update modems;
    return new PageReference('/' + modems.Name);
}


public ApexPages.StandardSetController setCon {
    get{
        if(setCon == null){
            size = 15;
            string queryString = 'SELECT Name, ModemActive__c, ModemCarrier__c, ModemCarrierData__c, DataPlanName__c, ESNNumber__c, ModemICCID__c, IMEINumber__c, IMSINumber__c, ModemIPEXT__c, ModemJob__c, ModemManufacturer__c, ModemModel__c, ModemPhone__c, PortForwarding__c, ModemIPPort__c, SIMNumber__c, ModemIPSlave__c, ModemStaticIP__c, ModemFirmwareVersion__c FROM Modem__c ORDER BY Name';
            setCon = new ApexPages.StandardSetController(Database.getQueryLocator(queryString));
            setCon.setPageSize(size);
            noOfRecords = setCon.getResultSize();
        }
        return setCon;
    }
    set;
}

public List<Modem__c> getModems()
{
    List<Modem__c> modemList = new List<Modem__c>();
    for(Modem__c w : (List<Modem__c>)setCon.getRecords())
       modemList.add(w);
    return modemList;
}

public PageReference refresh() {
    setCon = null;
    getModems();
    setCon.setPageNumber(1);
    return null;
}



public PageReference Search()
{
    if (modems.Name != null)
    {
        con = new ApexPages.StandardSetController(Database.getQueryLocator([SELECT Name, ModemActive__c,ModemCarrier__c,ModemCarrierData__c,DataPlanName__c,ESNNumber__c,ModemICCID__c, IMEINumber__c,IMSINumber__c,ModemIPEXT__c,ModemJob__c, ModemManufacturer__c,ModemModel__c,ModemPhone__c, PortForwarding__c, ModemIPPort__c,SIMNumber__c,ModemIPSlave__c,ModemStaticIP__c, ModemFirmwareVersion__c FROM Modem__c  Modem__c WHERE Name= :modems.Name]));  
        con.setPageSize(10);
    }
    else
    {
        con = null;
    }
    return null;
}

public Boolean hasNext {
    get {
        return setCon.getHasNext();
    }
    set;
}
public Boolean hasPrevious {
    get {
        return setCon.getHasPrevious();
    }
    set;
}

public Integer pageNumber {
    get {
        return setCon.getPageNumber();
    }
    set;
}

public void first() {
    setCon.first();
}

public void last() {
    setCon.last();
}

public void previous() {
    setCon.previous();
}

public void next() {
    setCon.next();
}
}

自定义 VF 页面＆＃39; Wells ＆＃39;页

以下是＆＃39; Wells ＆＃39;的自定义 visualforce 页面。页：

<apex:page controller="ModemController">
<apex:form >
    <apex:pageBlock id="pb">          
        <apex:pageBlockTable value="{!Modems}" var="m">    
            <apex:column value="{!m.Name}" />   
            <apex:column value="{!m.ModemManufacturer__c}"/>
            <apex:column value="{!m.ModemModel__c}"/> 
            <apex:column value="{!m.ModemICCID__c}"/> 
            <apex:column value="{!m.ModemIPEXT__c}"/>
            <apex:column value="{!m.ModemCarrier__c}"/>
            <apex:column value="{!m.ModemActive__c}"/>
        </apex:pageBlockTable>
         <apex:panelGrid columns="7">
            <apex:commandButton status="fetchStatus" reRender="pb" value="|<" action="{!first}" disabled="{!!hasPrevious}" title="First Page"/>
            <apex:commandButton status="fetchStatus" reRender="pb" value="<" action="{!previous}" disabled="{!!hasPrevious}" title="Previous Page"/>
            <apex:commandButton status="fetchStatus" reRender="pb" value=">" action="{!next}" disabled="{!!hasNext}" title="Next Page"/>
            <apex:commandButton status="fetchStatus" reRender="pb" value=">|" action="{!last}" disabled="{!!hasNext}" title="Last Page"/>
            <apex:outputText >{!(pageNumber * size)+1-size}-{!IF((pageNumber * size)>noOfRecords, noOfRecords,(pageNumber * size))} of {!noOfRecords}</apex:outputText>
            <apex:commandButton status="fetchStatus" reRender="pb" value="Refresh" action="{!refresh}" title="Refresh Page"/>
            <apex:outputPanel style="color:#4AA02C;font-weight:bold">
            <apex:actionStatus id="fetchStatus" startText="Fetching..." stopText=""/>
            </apex:outputPanel>
        </apex:panelGrid>           

    </apex:pageBlock>
</apex:form>

此控制器适用于其他标签页（请参阅＆＃39; Wells ＆＃39;页面，它使用相同的控制器，它可以正常工作！）但是不适用于＆＃39; 调制解调器＆＃39;页。

我们看到＆＃39; 调制解调器＆＃39;页面至少读取 7,549 记录（通过查看变量noOfRecords来计算有多少记录）但不显示它们。我甚至尝试将 LIMIT 添加到 SOQL 查询，但无济于事。（限制为2,000,1999,1001,1000,999，甚至30,20和10）

我不认为记录的数量是问题，我可能是错的。

如果有人有任何提示，我们将不胜感激！

Answer 1

此处的问题可能是因为您登录的用户的个人资料无法访问Well__c对象上的任何字段。

使用<apex:outputField />绑定时，VF页面会强制执行字段级安全性，并会隐藏用户无权访问的字段。

如果您查看此对象的字段级安全性，我怀疑您会发现您的个人资料无法访问您在列中使用的任何字段。 Modem__c对象的安全性可能已正确设置为其字段。

VisualForce页面不显示记录列表或任何记录，但它可以显示列表大小
