reloading mx:list with new data

[Andy]

I have an RSS reader Flex widget on YourMinis.

I want a button on click to reload data into an mx:list

Right now, the data for the mx:list is set this way:
dataProvider="{rssData1.channel.item}"

When I run the feed loader, it seems to process the feed but it
doesn't update the data.

Is there a way to force update the mx:list?

Thanks,
Andy

I am not much of a flex guy but good with flash as3 and its probably
the browser caching your feed. You just need to append a random
number var to the end of your url so it sees the feed as new every
time.
