DataModel must implement org.primefaces.model.SelectableDataModel when selection is enabled

Question

I was trying to implement one DataTable Editable with RowSelection enabled.

But it is throwing out an exception:

DataModel must implement org.

Answer 1

Possibly the error is because the row.id is empty or null in my case the solution be change this:

rowKey="row.id" 

to this:

rowKey="row" 

And the Object of datatable, for example

List collectionOfDataTable = new ArrayList<>();

Row (Object) implements Serializable:

public class Row implements Serializable{...}
