Question about listgridfield and formatting

[mathias]

Hello,

I have lots of listgridfields with different formatting needs. I have therefor implemented lots of custom cellformatters, for example like this:

public class ReportFloatFormatter implements CellFormatter {

    @Override
    public String format(Object value, ListGridRecord record, int rowNum, int colNum) {
        if (value == null) return null;
        try {
            Float flt = Float.parseFloat("" + value);
            return CommonConstants.defaultNumberFormat.format(flt);//this is '########0.##';
        } catch (Exception e) {
            return value.toString();
        }
    }
}

However, this means that when i have a databound listgrid for example, i still have to fetch out the individual fields and manually set the formatter in code for every place i want this custom format, like this:

ListGridField hoursField = grid.getField(NubaCommonConstants.[I]FIELD_HOURSFRACTION[/I]);
hoursField.setCellFormatter(floatFormatter);

This is a lot of code, and kind of counterintuitive since i define the fields in my datasource xml. It would be great if a listgrid somehow would know the formatting from the datasource xml definition.

So, my question:

Is there some better way to do this? I looked around at datasourcefield and found "setFormat", but i haven't been able to figure out if that could be used here somehow. Pointers would be much appreciated.
