Anyone know the specific function or process to add a row in a sublist *in SS2? Context is i've added a sublist via

context.Form.addSublist()

, and have successfully added fields with values, but have not found any documentation regarding adding "lines" or rows to it.

Sublist.setSublistValue on the line you want to set

for context, I'm inserting a sublist in a record that mirrors a pre-existing sublist with values. As an example, the pre-existing sublist has three lines with values in each field. When I run this specific code block with the intent of "mirroring" the sublist,

Sublist.setSublistValue()

doesn't insert another row past the first one.

var _r = record.load({ 
  type: "customrecord_slip", 
  id: _id
});
var _sub = _r.getSublist({ 
  sublistId: "recmachcustrecord_rec2"
});
var linecount = _r.getLineCount({ 
  sublistId:'recmachcustrecord_rec2' 
});

var slist = _f.addSublist({
  id : 'custpage_sublistid',
  type : ui.SublistType.LIST,
  label : 'Test Sublist'
});

      for(var i = 0; i < linecount; i++) {

		if(i == 0) {
          var sublist1 =  slist.addField({ id: 'sl_' + i + '_a', type: ui.FieldType.TEXT, label: 'Item' });
          var sublist2 =  slist.addField({ id: 'sl_' + i + '_b', type: ui.FieldType.TEXT, label: 'Reference' });
          var sublist3 =  slist.addField({ id: 'sl_' + i + '_c', type: ui.FieldType.TEXT, label: 'Quantity' });
          var sublist4 =  slist.addField({ id: 'sl_' + i + '_d', type: ui.FieldType.TEXT, label: 'Address' });
          var sublist5 =  slist.addField({ id: 'sl_' + i + '_e', type: ui.FieldType.TEXT, label: 'Date' });
        }

        var getVal1 = _r.getSublistValue({ sublistId:'recmachcustrecord_rec2',fieldId:'custrecord_tslipc_a',line:i });
        var getVal2 = _r.getSublistValue({ sublistId:'recmachcustrecord_rec2',fieldId:'custrecord_tslipc_b',line:i });
        var getVal3 = _r.getSublistValue({ sublistId:'recmachcustrecord_rec2',fieldId:'custrecord_tslipc_c',line:i });
        var getVal4 = _r.getSublistValue({ sublistId:'recmachcustrecord_rec2',fieldId:'custrecord_tslipc_d',line:i });
        var getVal5 = _r.getSublistValue({ sublistId:'recmachcustrecord_rec2',fieldId:'custrecord_tslipc_e',line:i });

        var setval1 = slist.setSublistValue({ id:'sl_' + i + '_a', line: i, value: getVal1});
        var setval2 = slist.setSublistValue({ id:'sl_' + i + '_b', line: i, value: getVal2});
        var setval3 = slist.setSublistValue({ id:'sl_' + i + '_c', line: i, value: getVal3});
        var setval4 = slist.setSublistValue({ id:'sl_' + i + '_d', line: i, value: getVal4});
        var setval5 = slist.setSublistValue({ id:'sl_' + i + '_e', line: i, value: getVal5});
      }

Am I missing a specific step here?

your field ids for your sublist arent sane

I see the issue now; an oversight in my planning for the for loop. Thanks.
