Sorting numbers as string

[vnta]

Hi
I'm using the latest smart get build with gwt1.4. I have a list grid column as int but some values are suppose to be null/empty but show up as 0 bc the field and it's content is int. When I make the listgrid field text and my data string, it show the null as empty, which is great but when I sort ascending or descending, it sort the number by 1st digit only so 12 will go before 2 as the one is smaller. Please advise? Any feedbacks will be very appreciated. I have this as a bug for a few weeks now and is desperate to get it fix. Thanks in advance for your time.

Declare the field as int, it's still allowed to return nulls. They will not render as 0s unless your server is sending them that way.

Isomorphic, thank you so much for the quick response.
It does work as you said.

I do not know why I had to change the DataSourceField from Int to Text when I changed my data type. If the datatype is String and having the DatasourceField as Int it works and sort properly.

Thanks again.
