Trying to compare elements in a list and aggregate quantity

I have based this code off of the VF Quote tool created by Salesforce.com Labs a couple of years back.

 

Esentially, I'm trying to take similar line items and get rid of them from the List and aggregate the quantity.  I end up with extra lines in my list for some reason.  I have a feeling it's because I'm trying to remove elements while in the loop, but I can't figure out another way to do this.

 

Any help is appreciated.

 

 

Quote_Item__c[] items = new Quote_Item__c[]{};
Quote_Item__c[] qiList = new Quote_Item__c[]{};

for(OpportunityLineItem oli:[select Maintenance_End__c, Maintenance_Start__c, quantity, unitprice, ListPrice, pricebookEntry.product2.name, pricebookEntry.product2id, pricebookEntry.product2.sort__c from opportunitylineitem where opportunityid = :opptyId order by pricebookEntry.product2.sort__c ASC]) 
{
	qiList.add(new Quote_Item__c(quantity__c = oli.quantity, unit_price__c = oli.unitprice, List_Price__c = oli.ListPrice, quote__c = renewalQuote.id, name = oli.pricebookentry.product2.name, sort__c = oli.pricebookentry.product2.sort__c, product__c = oli.pricebookentry.product2id, Maintenance_End__c = oli.Maintenance_End__c, Maintenance_Start__c=oli.Maintenance_Start__c));
}

// Iterate through working list
while(qiList.size()>0){
	Set<Id> removeAddress = new Set<Id>();
	Quote_Item__c qiTemp = qiList.get(0);
	removeAddress.add(qiTemp.Id);
	for(Quote_Item__c qi :qiList){
		If(qi.name==qiTemp.name && qi.unit_price__c==qiTemp.unit_price__c && qi.Maintenance_End__c==qiTemp.Maintenance_End__c && qi.Maintenance_Start__c==qiTemp.Maintenance_Start__c)
			{
				removeAddress.add(qi.id);
				qiTemp.Quantity__c += qi.Quantity__c;
			}
	}
	items.add(qiTemp);
	for(Id a : removeAddress){
		for(Integer i=0; i < qiList.size(); i++){
			if(a == qiList.get(i).Id)
			{
				qiList.remove(i);
			}
		}
	}
}

I don't know if this is the best way to do it, but it generally works for me. Essentially set your iterator back 1 since you removed an item and the indices have shifted.

 

 

 

 

for(Id a : removeAddress){
		for(Integer i=0; i < qiList.size(); i++){
			if(a == qiList.get(i).Id)
			{
				qiList.remove(i);
                                i--;
			}
		}
	}

I think you're correct that my issue is in the remove address loop, however, just moving the cursor back doesn't work either.  In my unit test where I should end up with 1 group, it works fine, but in my test where I shoul end up with 2 groups, I only have 1.

Okay, I think I'm following the code... here's another way of approaching it (if I understand it correctly). The idea being rather than trying to remove the indices after adding them, check your condition, and don't add them to the list in the beginning. Do you think this would work>

 

 

 

 

Quote_Item__c[] items = new Quote_Item__c[]{};
Quote_Item__c[] qiList = new Quote_Item__c[]{};

for(OpportunityLineItem oli:[select Maintenance_End__c, Maintenance_Start__c, quantity, unitprice, ListPrice, pricebookEntry.product2.name, pricebookEntry.product2id, pricebookEntry.product2.sort__c from opportunitylineitem where opportunityid = :opptyId order by pricebookEntry.product2.sort__c ASC]) 
{
	q = new Quote_Item__c(quantity__c = oli.quantity, unit_price__c = oli.unitprice, List_Price__c = oli.ListPrice, quote__c = renewalQuote.id, name = oli.pricebookentry.product2.name, sort__c = oli.pricebookentry.product2.sort__c, product__c = oli.pricebookentry.product2id, Maintenance_End__c = oli.Maintenance_End__c, Maintenance_Start__c=oli.Maintenance_Start__c);
	
	Boolean found = false;
	for(Quote_Item__c q_i : qiList)
	{
		if(qi.name==q.name && qi.unit_price__c==q.unit_price__c && qi.Maintenance_End__c==q.Maintenance_End__c && qi.Maintenance_Start__c==q.Maintenance_Start__c)
		{
			found = true;
		}
	}
	if(!found)
	{
		qiList.add(q);
	}
}

//DO THE AGGREGATING

Here is my query

 

orderHistListRec33 = [Select Name,Account__c,Order_Status__c, Case_Number__c, Product_Description__r.Is_Package__c, Product_Description__r.Name,CreatedDate
From Order_History__c order by createdDate dsc ];

 

I get 

 

 

List is 

 

OrderHistoryNumber (Name): 123    Product_Description__r.Name:Branding    CreatdeDate : 6/25/13

OrderHistoryNumber(Name) : 124    Product_Description__r.Name:CHAT    CreatdeDate : 6/25/13

OrderHistoryNumber (Name): 125    Product_Description__r.Name:Branding   CreatdeDate : 6/22/13

OrderHistoryNumber(Name) : 126     Product_Description__r.Name:CHAT    CreatdeDate : 6/22/13

 

I want to eleiminate duplicate Product_Description__r.Name and get most recent i.e. 

 

 

OrderHistoryNumber (Name): 123    Product_Description__r.Name:Branding    CreatdeDate : 6/25/13

OrderHistoryNumber(Name) : 124    Product_Description__r.Name:CHAT    CreatdeDate : 6/25/13

 

how do i modify my query .
