Product Approval

Here, im using a wrapper class to display the list of products from the opportunity and using a checkbox when the user selects the products and clicks "approve" button i update a field with the value "Approved"  in the product record.

The problem im facing here is, when i select all the products and click "approve" the update works. And for the first time if i select one product of the two products and click "approve", the update works. But the next time if i select the other product and click "approve" the button is not getting fired. While the second time i click the same "approve" consecutively it works. Im not able to figure out whats the reason for this behaviour.

Please suggest what to do.

Code:

public class cls_Approve
{
    public cls_Approve(ApexPages.StandardController controller)
    {
        opp = (opportunity)controller.getRecord();        
        oppLineItem = [Select PricebookEntry.Product2.id,PricebookEntry.Product2.name , PricebookEntry.Product2.HD_Product_Approval__c from OpportunityLineItem where OpportunityId  =: opp.id];
    }
    public class wrapProduct
    {
        public boolean chkProduct{get;set;}       
        public string wrapLineItemName{get;set;}
        public string wrapLineItemId{get;set;}
        public Opportunity wrapOpp{get;set;}      
        public wrapProduct(Opportunity op)
        {
            wrapOpp =  op;
        }
    }       
    public List<wrapProduct> getwrapProdList()
    {
        queryResults = new List<wrapProduct>();
        for(opportunityLineItem oli : oppLineItem)
        {
            wrapProduct wpObj = new wrapProduct(opp);          
            if(oli.PricebookEntry.Product2.name != null)
            {                
                wpObj.wrapLineItemName = oli.PricebookEntry.Product2.name;
            }
            wpObj.wrapLineItemId = oli.PricebookEntry.Product2.id;                            
            queryResults.add(wpObj);
        }        
        return queryResults;            
    }                 
    public List<string> updateProdId = new List<string>();
    public List<product2> updateProd2 = new List<product2>();
    public List<product2> pList = new List<product2>();   
    public pagereference approveProduct()
    {                                         
        for(wrapProduct wpList:queryResults)
        {                                         
            if(wpList.chkProduct == true)
            {
                updateProdId.add(wpList.wrapLineItemId);                         
            }                       
        }        
        if(updateProdId.size() >0)
        {                        
            pList = [select HD_Product_Approval__c from  product2 where id in: updateProdId];           
        }
        for(product2 p2:pList)
        {            
            p2.HD_Product_Approval__c = 'Approved';
            updateProd2.add(p2);                                       
        }       
        update updateProd2;          
        return null;
    }

In the contract object i have added a custom look up field for products. This lookup shows all the products in the organisation. But i want to filter the display in such a way that only the Opportunity Line Items(opportunity products) of the opportunity associated with this contract to appear in the lookup dialog from which the user can choose.

Any suggestions??

How do i do this?  

In visual force page i use a standard controller contract and the extension as wrapper class.
