Grid Refresh Question

Hello,

I'm trying to figure out how to refresh the grid after doing the following in a JSP.

var aUrl = action + ".do?actionType=" + actionType;
var r = new AW.HTTP.Request;
r.setURL(aUrl);
r.setRequestMethod("POST");
r.request();

In my example I'm calling r.request(), the grid is still displaying the original data and not the re-retrieved data.

Can anyone help me on how to do this? If I use a regular form submit the grid is refreshed correctly.

Thanks in advance!

Gary
