Having problem creating an Attachment section

I have a  page that lists a user's cases

The user can drill down on a case number and get to a page that displays the case details.

I want to add an Add an Attachment section.

 

I am probably doing some needless looping.  I am missing the connection to the record that I need to add the comment to. The case number should be available to me since this page is the case number's details.

 

This is the error I am getting:

Visualforce Error

 

System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Parent]: [Parent]

 
Error is in expression '{!Upload}' in page viewed_request_attachment

Class.RequestViewExtension.upload: line 53, column 1

 

Line 53 is:          insert myAttachment; 

 

Here is my page:

 

<apex:page standardController="Case" extensions="RequestViewExtension" tabStyle="My_Requests__tab">
<apex:stylesheet value="/resources/ForteStyles.css"/>
<apex:form >
    <apex:pageBlock >

You are not providing the parent Id

 

I just made the current record as the parent of the attachement

 

public class RequestViewExtension {
    public Case cs;
    ApexPages.StandardController controller;


    public RequestViewExtension(ApexPages.StandardController con) {
        controller = con;
        this.cs = (Case) con.getRecord();
    }
    public CaseComment objCaseComment {
        get;
        set;
    }
    public list < Case > case1 {
        get;
        set;
    }
    public list < Case > getcases() {
        case1 = [Select Priority, CaseNumber, (select CommentBody from CaseComments), id, Accountid, Subject, Description, Contactid, Ownerid, CreatedDate from
        case where CaseNumber = :
            ApexPages.currentPage().getParameters().get('CaseNumber')
        ];
        return case1;
    }
    public Attachment attachment {
        get;
        set;
    }

    public String Comment {
        get;
        set;
    }
    public string fileName {
        get;
        set;
    }

    public string fileParent {
        get;
        set;
    }

    public Blob fileBody {
        get;
        set;
    }
    public string fileDesc {
        get;
        set;
    }

    public PageReference upload() {
        PageReference pr;
        if (fileBody != null && fileName != null) {
            Attachment myAttachment = new Attachment();
            myAttachment.Body = fileBody;
            myAttachment.Name = fileName;
            myAttachment.Description = fileDesc;
            myAttachment.OwnerId = UserInfo.getUserId();
            myAttachment.ParentId = cs.Id;
            insert myAttachment;
            pr = new PageReference('/' + myAttachment.Id);
            pr.setRedirect(true);
            return pr;
        }
        return null;
    }
}

Error is in expression '{!Upload}' in page viewed_request_attachment
