Found a solution: - Changed the Java servlet to concatenate the time in milliseconds to the filename, ensuring it will be unique. Earlier, the filename for that record was the same as its ID; this increased the likelihood of caching. - Modified the Flex app to refresh the dataProvider for the grid with each upload. Based on a tip by a blogger (http://joelhooks.com/2008/02/07/flex-preventing-datagrid-scrolling-when-the-dataprovider-is-updated/), I'm able to put the user back at the same record again after the refresh.
Hope this helps others running into this issue. --- In [email protected], "oneworld95" <[EMAIL PROTECTED]> wrote: > > I've got a datagrid which displays an image (if one has been uploaded) > for each record.
