Can anyone provide a sample code to update Customer address sublist?
I need to check if a customer has address and if it is there update the address otherwise add the address.

I have sample code for adding sublist.

 function addAddress(cusRecord, dataIn) {        cusRecord.selectNewLineItem('addressbook');        cusRecord.setCurrentLineItemValue('addressbook', 'defaultshipping', 'T');          cusRecord.setCurrentLineItemValue('addressbook', 'defaultbilling', 'T');           //create address subrecord        var subrecord = cusRecord.createCurrentLineItemSubrecord('addressbook', 'addressbookaddress');            //set subrecord fields        subrecord.setFieldValue('country', (dataIn.Country||'')); //Country must be set before setting the other address fields        subrecord.setFieldValue('addr1', (dataIn.Address1||''));        subrecord.setFieldValue('addr2', (dataIn.Address2||''));        subrecord.setFieldValue('city', (dataIn.City||''));        subrecord.setFieldValue('state', (dataIn.State||''));        subrecord.setFieldValue('zip', (dataIn.Zip||''));             //commit subrecord and line item        subrecord.commit();        cusRecord.commitLineItem('addressbook');    }
