ParticipantHi, until Smart UI v12.0.0 i used to initialize an empty grid like this :
const data = null;
Smart(‘#myEmptyGrid’, class {
get properties() {
return {
dataSource: data,
columns: [myDefinedColumns]
}
}
});after updating to Smart UI v14.0.0 i get this error at smart.grid.js:1437:
Uncaught TypeError: Cannot read properties of undefined (reading ‘set’)

KeymasterHi,
We will need more information about that, because we are unable to reproduce it https://codepen.io/jqwidgets/pen/OJQNmZJ?editors=1112

Participantwindow.onload = function () {
initGrid();
};
function initGrid() {
Smart(“#grid”, class {
get properties() {
return {
selection: {
enabled: false,
allowRowSelection: false,
checkBoxes: {
enabled: true
}
},
onCommand: function (args) {
if (args.name === “commandColumnRowMenuCommand”) {
const row = args.details;
const menu = document.getElementById(“menuGrid”);
args.event.preventDefault();
let contextMenuGridOpenedOn = args.details;
window.numOrdine = contextMenuGridOpenedOn.data.NumeroOrdine;
menu.open(args.event.pageX – 30, args.event.pageY – 80);
args.handled = true;
}
},
editing: {
enabled: true,
mode: “row”,
action: “none”,
dialog: {
enabled: true
},
commandColumn: {
visible: true,
position: “near”,
dataSource: {
commandColumnMenu: {
visible: true
},
commandColumnRowMenu: {
visible: true
}
}
}
},
dataSource: [],
columns: [
{
label: “IDCliente”,
dataField: “IDCliente”,
dataType: “number”
},
{
label: “IDAzienda”,
dataField: “IDAzienda”,
dataType: “number”
},
{
label: “aziNome”,
dataField: “aziNome”,
dataType: “string”
}
]
};
}
}
);
}the problem seems to be commandColumn property inside editing,If i remove it the grid work fine.
In your codepen commandColumn has no problem, is it because u call an instance of smart.dataAdapter?

KeymasterHi,
Unfortunately, we cannot reproduce this and we will need a complete codepen sample or something similar. Here is our test code based on your last post:
Smart('#grid', class { get properties() { return { sorting: { enabled: true }, editing: { enabled: true, mode: 'row', action: 'none', dialog: { enabled: true }, commandColumn: { visible: true, position: "near", dataSource: { commandColumnMenu: { visible: true }, commandColumnRowMenu: { visible: true } } } }, locale: 'de', selection: { enabled: false, allowRowSelection: false, checkBoxes: { enabled: true } }, filtering: { enabled: true }, behavior: { allowColumnReorder: true }, onCommand: function (args) { if (args.name === "commandColumnRowMenuCommand") { const row = args.details; const menu = document.getElementById("grid"); args.event.preventDefault(); let contextMenuGridOpenedOn = args.details; window.numOrdine = contextMenuGridOpenedOn.data.NumeroOrdine; menu.open(args.event.pageX - 30, args.event.pageY - 80); args.handled = true; } }, dataSource: [], columns: [ { label: 'First Name', dataField: 'firstName', filterMenuMode: 'excel' }, { label: 'Last Name', dataField: 'lastName' }, { label: 'Date', dataField: 'date', align: 'right', cellsAlign: 'right', }, { label: 'Product', dataField: 'productName' }, { label: 'Quantity', dataField: 'quantity', align: 'right', cellsAlign: 'right', } ] } } });
No errors in the console. The grid displays with columns and empty data source.

there you go.
if u inspect the page u can see this sample trigger the error :
Uncaught TypeError: Cannot read properties of undefined (reading ‘set’).
if u remove commandColumn property the grid works fine.
