component issue

Question

I have an component which will display all opportunity records created today and whose amount is greater than 50000.

I am not able to see any data when I preview the visualforce page.

controller code:

public String accID{get;set;}
public List<Opportunity> oppList{get;set;}
public List<Opportunity> getoppList()
   {
     if (oppList == NULL)
     {
      accID=ApexPages.currentPage().getParameters().get('ID');
       oppList=[select Name,Account.Name,StageName,Amount,CloseDate from 
                Opportunity 
                where 
                AccountID=:accID;
                AND 
                Amount >= 50000
                LIMIT 10000];
     }
  return oppList;
    }

The component is as follows:

<apex:component controller="acctTemplate"
                access="global">

  <apex:attribute assignTo="{!accID}"
                  name="AccountID"
                  description="ID of the Account"
                  type="String"/>
<apex:repeat value="{!oppList}" 
                     var="opp">
        <tr>
            <td>{!opp.Name}</td>
             <td>{!opp.Account.Name}</td> 
</apexrepeat>

I am calling this component inside as visualforce page as follows:

<apex:page sidebar="false">
  <c:opptylist></c:opptylist>
</apex:page>

Answer 1

issue here 2 variable with same name i.e. oppList and getoppList. both variable can access in vf using {!oppList } that's the issue.

below code should fix the issue

public String accID{get;set;}

public List<Opportunity> getoppList()
{
      accID=ApexPages.currentPage().getParameters().get('ID');
      return Database.Query('select Name,Account.Name,StageName,Amount,CloseDate from'+
                            ' Opportunity  where AccountID=:accID '+
                            ' AND Amount >= 50000 LIMIT 10000 ');
}

OR

private List<Opportunity> lstOpp;
public List<Opportunity> getoppList()
{
     if (lstOpp== NULL)
     {
       accID = ApexPages.currentPage().getParameters().get('ID');
       lstOpp = [select Name,Account.Name,StageName,Amount,CloseDate from 
                        Opportunity 
                        where 
                        AccountID=:accID;
                        AND 
                        Amount >= 50000
                        LIMIT 10000];
     }
     return lstOpp;
 }
