java.lang.UnsupportedOperationException for removing a row from the javafx tableview

Question

I am trying to delete the selected record from the tableview in javafx. Below is how I am populating the table with the data:

public void setMainApp(MainAppClass         


        

Answer 1

Remove the data from the underlying list, not the filtered/sorted list:

FileModel selectedItem = fileTable.getSelectionModel().getSelectedItem();
if (selectedItem != null) {
    mainApp.getFileData().remove(selectedItem);
}
