MISSING_ARGUMENT, Id not specified in an update call

on button click on opportunity... i am showing opportunityline items records on a page with line number using repeat.

I have used wrapper class for showing line number.

My Problem

opportunityline items fields are editable on page..so user can update them...i am having problem updating it...how to specify id for updating...

 

in Constructor

List<OpportunityLineItem> oli;
oli=[Select Id,opportunityId From OpportunityLineItem where opportunityId=:id];
showsavedoppLineitems();

 

 wrapper class

public list<linenumberclass> wrapperopllist;//List used in repeat on page
public Class linenumberclass
{
    public integer lineNumber{get;set;}
    public OpportunityLineItem oppLineNo{get;set;}
    

   
     public linenumberclass(OpportunityLineItem oppLineNo,Integer lineNumber)
    {
        this.oppLineNo=oppLineNo;
        this.lineNumber=lineNumber;
    }

}

 method called from constructor

public void showsavedoppLineitems()
{   
    
 List<OpportunityLineItem> lOpp=[select id,Business_Type__c,pricebookentry.pricebook2id,pricebookentryid from OpportunityLineItem where id in:opplineIttems]; 
   for(OpportunityLineItem l:lOpp)
    {    
         opline = new OpportunityLineItem ();
         opline.OpportunityId=id;
         opline.pricebookentry=pre.get(l.pricebookentryid);
         opline.pricebookentryid=l.pricebookentryid;
         opline.Territory1__c=l.Territory1__c;
         wrapperopllist.add(new linenumberclass(opline,m));
          m++;
    }
}

 

i am calling this method on button click...so i have the updated record value in oplist...

 

public list<OpportunityLineItem > opllist{get;set;}

 



public void add{

for(linenumberclass ln:wrapperopllist)
        {
           opline = new OpportunityLineItem ();
           opline.opportunityid=id;
           opline.PricebookEntry=ln.oppLineNo.pricebookentry;
           opline.PricebookEntryid=ln.oppLineNo.pricebookentryid;
           opline.Line__c=ln.linenumber;
           opllist.add(opline);
        }

}

i dont know how to update oplist.... 

 

 

As i am showing the records in editable mode...if any user edits them and click on them records should be updated .

i dont know how to update existing records.i dont how to pass id.

please help me out this...thanks

So if you want to edit these records... change your method called to construct the list to...

 

public void showsavedoppLineitems()
{   
    //i would put my initializers in here
wrapperopllist = new List<linenumberclass>();
m = 0;
 List<OpportunityLineItem> lOpp=[select id,Business_Type__c,pricebookentry.pricebook2id,pricebookentryid from OpportunityLineItem where id in:opplineIttems]; 
   for(OpportunityLineItem l:lOpp)
    {    
         wrapperopllist.add(new linenumberclass(l,m));
          m++;
    }
}

 You dont need to construct new line items...then change your add method and add an update statement on the list...

public void add{
//initialize list
opllist = new List<opportunitylineitem>();
for(linenumberclass ln:wrapperopllist)
        {
           opllist.add(ln.oplineNo);
        }
update opllist;

}

hey thanks andrew for replying...

 

in showsavedoppLineitems() methods

 

Map<id,Pricebookentry> pre=new Map<id,Pricebookentry>();


         opline = new OpportunityLineItem ();//any way i can send id here
         opline.OpportunityId=id;
         opline.pricebookentry=pre.get(l.pricebookentryid);         opline.pricebookentryid=l.pricebookentryid;
         opline.Business_Type__c=l.Business_Type__c;

 on page i am also showing "oppLineNo.PricebookEntry.Product2.name" which i dont get if i use your way...i get an exception.any way i can send that to wrapperopllist.

 

System.SObjectException: SObject row was retrieved via SOQL without querying the requested field: PricebookEntry.Product2 

 

 

 

 

for(OpportunityLineItem l:lOpp)
    {    
         wrapperopllist.add(new linenumberclass(l,m));
          m++;
    }

Since you are querying an object and using it in your page...You must query every field you want in your SOQL. So you need to add any fields referenced in your controller or page in the soql.

thanks andrew...but...as i an using a map to show "oppLineNo.PricebookEntry.Product2.name" on page...

Map<id,Pricebookentry> pre=new Map<id,Pricebookentry>();

         opline = new OpportunityLineItem ();//any way i can send id here
         opline.OpportunityId=id;
         opline.pricebookentry=pre.get(l.pricebookentryid);                opline.pricebookentryid=l.pricebookentryid;
         opline.Business_Type__c=l.Business_Type__c;

 as i cant query this field on opportunitylineitem....using your way as i am not able to show everything on page....is there any other to send id...pl bear with me if i am wrong somewhere..as i am learning....

 for(OpportunityLineItem l:lOpp)
    {    
         wrapperopllist.add(new linenumberclass(l,m));
          m++;
    }
