New rows are not shown when using databinding with bindcolumns

    I don't know if it is by design but if I bind the a sheet to a datasource (a simple array) for the first time, all rows are shown.
    If I now add a record to the datasource array, the sheet does not show this row even after calling spread.refresh() or even setting the datasource again.

    Is this by design? How would I update the sheet to reflect the new row?

    (see attached an example)

    Thank you!

    Hi Gerald,

    For adding a new row you may use the addRows method. Please refer to the following code snippet and let us know if you face any issues.

    let newItem = new Item();
    newItem.itemId = 500;
    newItem.itemName = "hello, a new one";
    newItem.parentItemId = 500;
    newItem.rowIndentLevel = 2;
    newItem.rowIndex = 2

    this.dataSource.items.splice.apply(this.dataSource.items, [this.sheet.getRowCount()-1, 2,newItem]);

    You may also refer to the attached updated sample.
