在字符串列表中填充Visualforce頁面中的下拉列表

Question

我試圖模仿salesforce鉛轉換過程。我有一個visualforce頁面和一個控制器。我遇到的問題是當頁面加載下拉列表時是空白的。我的目標是擁有一個字符串列表並用這個列表填充下拉列表。我搜索了高和低，並不知道爲什麼下拉是空白的。這裏是我的代碼，任何幫助表示讚賞。

--controller--

public with sharing class LeadConvertController { 
    public Lead l {get; private set;} 
    public Account a {get; private set;} 
    public list<SelectOption> options {get; set;} 
    public String attachToclient {get; set;} 

    public LeadConvertController(ApexPages.StandardController sc) { 
     for (Lead referral : [SELECT Id, Name, Phone, OwnerId 
           FROM Lead 
           WHERE Id = : sc.getId()]) { 
      l = referral; 
     } 

     if (l == null) { 
      system.debug(logginglevel.error, 'Missing lead'); 
     } 

     //query by name and phone to find possible Existing Accounts or contact 
     options = findExistingClients(l); 
    } 
    public list<SelectOption> findExistingClients (Lead leadToacc) { 
     list<SelectOption> findClients = new list<SelectOption>(); 
     for (Account acc : [SELECT Id, Name, Type, Primary_Contact__c FROM Account WHERE            Name = :leadToacc.Name OR Phone = :leadToacc.Phone]) { 
      findClients.add(new SelectOption(acc.Id, 'Attach to Existing: ' + acc.Name)); 
      a = acc; 
     } 
     for (Contact c : [SELECT Id, Name FROM Contact WHERE Name = :leadToacc.Name OR Phone = : leadToacc.Phone]) { 
      findClients.add(new SelectOption(c.Id, 'Attach to Existing: ' + c.Name)); 
     } 

     findClients.add(new SelectOption(l.Name, 'Create new Client/Prospect: ' + l.Name)); 
     return findClients; 
    } 
} 

--visualforce page--

<apex:page title="Lead Convert" standardController="Lead" tabStyle="Lead" extensions="LeadConvertController"> 
<apex:sectionHeader title="Convert Referral" subtitle="{!l.Name}"> 
    <apex:outputPanel id="main" rendered="true"> 
     <apex:form> 
      <apex:pageBlock> 
       <apex:pageBlockButtons> 
        <apex:commandButton action="{!convert}" id="Convert" value="Convert" /> 
        <apex:commandButton action="{!cancel}" id="Cancel" value="Cancel" /> 
       </apex:pageBlockButtons> 
       <apex:pageBlockSection title="Convert Referral" collapsible="false" columns="1"> 
        <apex:inputField label="Record Owner" value="{!l.OwnerId}" required="true" /> 
        <apex:pageBlockSectionItem> 
         <apex:outputPanel> 
          <apex:outputLabel value="Client/Prospect Name" /> 
          <apex:selectlist value="{!attachToclient}" required="true" /> 
          <apex:selectOptions value="{!options}" /> 
          <apex:outputlink title="View" value="{!a.Primary_Contact__c}">View</apex:outputlink> 
         </apex:outputPanel> 
        </apex:pageBlockSectionItem> 
       </apex:pageBlockSection> 
      </apex:pageBlock> 
     </apex:form> 
    </apex:outputPanel> 
</apex:sectionHeader> 
</apex:page> 

Answer 1

頂點：selectOptions必須開始標記和結束標記之間的 「頂點：選擇列表的」。

請使用如下代碼：

<apex:page title="Lead Convert" standardController="Lead" tabStyle="Lead"  extensions="LeadConvertController"> 
<apex:sectionHeader title="Convert Referral" subtitle="{!l.Name}"> 
<apex:outputPanel id="main" rendered="true"> 
    <apex:form> 
     <apex:pageBlock> 
      <apex:pageBlockButtons> 
       <apex:commandButton action="{!convert}" id="Convert" value="Convert" /> 
       <apex:commandButton action="{!cancel}" id="Cancel" value="Cancel" /> 
      </apex:pageBlockButtons> 
      <apex:pageBlockSection title="Convert Referral" collapsible="false" columns="1"> 
       <apex:inputField label="Record Owner" value="{!l.OwnerId}" required="true" /> 
       <apex:pageBlockSectionItem> 
        <apex:outputPanel> 
         <apex:outputLabel value="Client/Prospect Name" /> 
         <apex:selectlist value="{!attachToclient}" required="true" /> 
         <apex:selectOptions value="{!options}" /> 
         </apex:selectlist> 
         <apex:outputlink title="View" value="{!a.Primary_Contact__c}">View</apex:outputlink> 
        </apex:outputPanel> 
       </apex:pageBlockSectionItem> 
      </apex:pageBlockSection> 
     </apex:pageBlock> 
    </apex:form> 
</apex:outputPanel>
