I have a field editors with one custom snippet each. When I run the two pieces of code separately, they both load. When I run them together, I sometimes get this error:

Uncaught TypeError: Cannot read property ‘tid’ of undefined


Here are the two pieces of code:

PieceName

var params = argumentse0], $ = skuid.$;

var field = argumentse0];

var model = field.model;

var row = field.row;

var HtmlString = ‘’;

var ActName = row.Name;

var Piece = row.Piece__r;

if(Piece){

console.log(Piece.Name);

//var PieceWriterModel = skuid.model.getModel(“MMA_Music_Piece_Writer”);

//var MusicPieceCondition = PieceWriterModel.getConditionByName(“MMA_Music_PieceId”);

//var PieceId = Piece.Id;

var Piece_Name = Piece.Name;

HtmlString = ‘

’;

//var cellElem = field.element;
//console.log(HtmlString);
//cellElem.html(HtmlString);

}

else{

HtmlString = ActName + ‘’;

window.alert(ActName + ’ - There is no peice in thie Act.')

//cellElm = field.element;

}

var NoOfWriters = 0;

var MusicWriter =‘none’;

if(Piece){

var PieceWriterModel = skuid.model.getModel(“MMA_Music_Piece_Writer”);

var MusicPieceCondition = PieceWriterModel.getConditionByName(“MMA_Music_PieceId”);

var PieceId = Piece.Id;

PieceWriterModel.setCondition(MusicPieceCondition,PieceId);

console.log(‘After Set condition’ + PieceId + ’ PieceId ‘);

PieceWriterModel.updateData(function(){

NoOfWriters = PieceWriterModel.data.length;

if(NoOfWriters>0){

for(i=0;i<NoOfWriters;i++){

if(PieceWriterModel.dataWi].MMA_Music_Composer__c){

MusicWriter = PieceWriterModel.data)i].MMA_Music_Composer__r.Name;

HtmlString = HtmlString + ‘

’;

HtmlString = HtmlString + Writer_Role_String;

                    }

                else{

                    }}

                    else{

                        window.alert(Piece_Name + ' - This Piece does not have any associated Music Writers.');

                    }

            }

            var cellElem = field.element;

            cellElem.html(HtmlString);

        }

    });

   



    

}

else{

}
