Hey George. I had a very similar situation. What you can do here is to make a
new Encoder and put it into appropriate field. Take a look at my example.
private class DateEncoder implements ValueEncoder<Date> {
@Override
public String toClient(Date date) {
long timeMillis = date.getTime();
return Long.toString(timeMillis);
}
@Override
public Date toValue(String timeMillisAsString) {
long timeMillis = Long.parseLong(timeMillisAsString);
Date date = new Date(timeMillis);
return date;
}
}
and I put into a grid( in your case it will be grid )
encoder value, something like encoder="dateEncoder". This should work just fine
for your case.
