My Test method covered the wrapper class at only 63%:  Lines 11 - 14 were not covered.

My Test Method calls this ref via the controller extenstion.  Why are these lines omitted?  Thanks

Some extension excerpts are:

public List<OpportunityLineItem> getOpportunityItemListNotDeleted(){
//List for display on the view.
List<OpportunityLineItem> listToDisplay = new List<OpportunityLineItem>();
for (OpportunityLineItem item : opportunityLineItemList){
if (item.isDeleted != true){
listToDisplay.add(item);
}
}

return listToDisplay;
}

---

private List<TripOpportunityAssociation__c> opportunityList {
get{
List<TripOpportunityAssociation__c> returnValue = new List<TripOpportunityAssociation__c>();
if(opportunityList == null && reportId != null) {
returnValue = TripRptManager.getOpportunitiesForReport(reportId);
}
return returnValue;
}
set;
}

//List of wrapper objects.
private List<OpportunityLineItem> opportunityLineItemList{
get{
if (opportunityLineItemList == null){
opportunityLineItemList = new List<opportunityLineItem>();

//Only loaded on isUpdate.
if (isUpdate){

for(TripOpportunityAssociation__c opportunity : opportunityList ){
opportunityLineCount ++;
OpportunityLineItem lineItem = new OpportunityLineItem( opportunityLineCount , opportunity);
opportunityLineItemList.add(lineItem);
}
}
}
return opportunityLineItemList;
}
set;
}

//Renumber the lines in the list.
private void renumberOpportunityLineItemList(){
opportunityLineCount = 0;
for ( OpportunityLineItem item : opportunityLineItemList ){
item.lineNumber = 0;
if (item.isDeleted == false){
opportunityLineCount++;
item.lineNumber = opportunityLineCount;
}
}
}

The class is:
