How to force ListGrid.fetchData() to fetch data from server?

Smart GWT Technical Q&A

Hi,

I understand that SmartClient will always try to avoid requests to server by checking if the criteria is more or less restrictive.

But what i need is to force fetchData to get rows from server. Note that i don’t want invalidaCache() because my criteria is different.

So, is there a way to explicitly force fetchData to request rows from server?

Thanks.

You’re saying that on any criteria change you want to hit the server?
If so - sounds like you need to setCriteriaPolicy to dropOnChange.
