VisualForce页面不显示记录列表 - 标题说明了所有内容。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
如何得到VF页面显示，这显然是计数的记录（因为它说的记录1-15）。
是这样的：

然而，这是我们希望它看起来像：
（我们目前有工作的人！） http://i.imgur.com/uwXOsHS.png - '调制解调器'页面（由于我们工作的公司可能不希望披露此信息）
我的团队正在开发一个salesforce.com应用程序，我们有一个对象'调制解调器'，其中包含大约7,500记录。
ModemController
我们已经创建了一个自定义的控制器，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();
}
}
定制VF页'井页面
这里是习俗visualforce页的“井页面：
<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>
这控制器其他选项卡工作，（见“井”页面，它使用相同的控制器和它的作品！ ）但不适用于'调制解调器'页面。
我们看到，“调制解调器”页面在记录至少读（通过观察变量noOfRecords算多少有一些），但不显示它们。我甚至试图将LIMIT添加到SOQL查询中，无济于事。 （限于2000年，1999年，1001年，1000年，999年，甚至30,20年和10年）
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，将不胜感激！
WellController如果有人要求，这里是为“井页面运行的代码，都VisualForce和顶点代码： WellController： 公共类WellController {
