Passing URL to SWF

Hello  All,

I have started learning Adobe Flex recently for purpose of my project. We are planning to use Flex 4.0 Charts. So I need your help regarding the same.

I am creating my swf object using Eclipse and Flex SDK. I need to use mxml httpService for fetching xml data from a query template. I am able to create swf object when my url is hard-coded in my mxml code. But the requirement is to send it dynamically from web page depending on selection of inputs. If I pass my url as a parameter of swfobject, the url is send to object but it does not get/plot any data.

Please help with the same soon.

Regards,

Snehal
