How to inset a customer location through graph - acumatica

Question

Hello I am banging my head against the wall trying find the correct way to insert a customer location using a graph. I am currently using the PX.Objects.CR.CustomerLocationMaint graph. But when I insert or set current location it is always null.
Here is my code
private PX.Objects.CR.Location UpdateCustomerLocation(PX.Objects.AR.Customer cust, ListingRead currentListing, ListingContactRelnListing contact)
{
PX.Objects.AR.CustomerLocationMaint g = new PX.Objects.AR.CustomerLocationMaint();
g.Clear(PXClearOption.ClearAll);
g.BusinessAccount.Current = cust;
PX.Objects.CR.Location loc = new PX.Objects.CR.Location();
loc.BAccountID = cust.BAccountID;
loc.LocationCD = "RL" + contact.contact.id;
loc.Descr = currentListing.property.system_search_key;
loc.DefContactID = cust.DefContactID;
loc.IsActive = true;
loc.LocType = "CU";
g.Location.Current = loc;
loc = g.Location.Insert(loc);
PX.Objects.CR.Address addr = new PX.Objects.CR.Address();
addr.BAccountID = cust.BAccountID;
addr.AddressType = "BS";
addr.CountryID = "NZ";
addr.AddressLine1 = currentListing.property.adr_street_number + " " + currentListing.property.adr_street_name;
addr.AddressLine2 = currentListing.property.adr_suburb_or_town;
addr.AddressLine3 = currentListing.property.adr_state_or_region;
addr = g.Address.Insert(addr);
loc.DefAddressID = addr.AddressID;
g.Location.Update(loc);
g.Actions.PressSave();
return loc;
}
