Calculated and summary column (ListGrid)

[escomvicto]

Hi everybody,

I have a listgrid with a calculated and summary column, the calculated value is showed correctly but the summary doesn't work. Can anybody give me some help ?

This is the code for the column:

ListGridField importeField = new ListGridField("importe", "Importe");
importeField.setType(ListGridFieldType.FLOAT);
importeField.setShowGridSummary(true);
importeField.setCanEdit(false);


importeField.setCellFormatter(new CellFormatter() {
public String format(Object value, ListGridRecord record, int rowNum, int colNum) {
if(record != null){
Double importe = new Double(ConvertUtil.convertIsNumberNull(record.getAttribute("valorunitario"))) * new Double(ConvertUtil.convertIsNumberNull(record.getAttribute("cantidad")));
NumberFormat nf = NumberFormat.getFormat("#,##0.00");

record.setAttribute("importe",importe);
return "$" + nf.format(((Number) importe).doubleValue());
} else {
NumberFormat nf = NumberFormat.getFormat("#,##0.00");
return "$" + nf.format(((Number) 0).doubleValue());
}
}
});
