Attachments are not displayed in a Pageblock Table

Question

I have a visualforce page that will display the attachments from A custom Object based on the Current logged in Portal user AccountID and ContactID.

The custom object is Child(LookUp Rel) of Account object.

I am getting the Attachments list in a debug logs but the list is not rendered in PageBlockTable

Any one have look a into my issue.

public with sharing class ViewServiceDocs_cntrlr 
{

public User currentUser                                             {get; set;}
public Contact currentContact                                       {get; set;}        
public Account currentAccount                                       {get; set;}      
Public List<Attachment> Attach{get;set;}

Public ViewServiceDocs_cntrlr()
{


currentUser = [select id,name,IsPortalEnabled,AccountId,ContactId from user where IsPortalEnabled=true and ID=:UserInfo.getUserId()]; 



 currentContact = [select Id, LastName, Name, AccountId from Contact where Id =: currentUser.ContactId]; 
 currentAccount = [select Id, Name, RecordType.name from Account where Id =: currentContact.AccountId]; 


 if(currentAccount.RecordType.name=='Generator')
 {


 List<Attachment> Attach = new list<Attachment>();
 Attach = [SELECT Id,Name,ContentType,Description,OwnerId,ParentId FROM Attachment where parentId in 
 (select id from Manifest__c where Generator_Old__r.ID=:currentAccount.ID)];
   system.debug('-----------Attach------------'+Attach);
 }

 else If(currentAccount.RecordType.name=='Customer')
 {

  Map<ID,Account> ParentAcc = new map<ID,Account>([SELECT Id,name FROM Account where parentId =:currentAccount.id]);
  system.debug('-----ParentAcc------------------------>'+ParentAcc);
  system.debug('-----ParentAcc Key----------------->'+ParentAcc.Keyset());


List<Attachment> Attach = [SELECT Id,Name,OwnerId,ParentId FROM Attachment where parentId in 
(select id from Manifest__c where Generator_Old__r.ID in:ParentAcc.keySet())];

system.debug('------------------------Attach--'+Attach);
 }

}
}

Answer 1

You are declaring local variables called Attach that are hiding (taking precedence over) the Attach field that the Visualforce is tied to.

So instead of:

List<Attachment> Attach = new list<Attachment>();

use:

Attach = new list<Attachment>();
