How to set the xmlconnector properties (xmlconnector.url) using a combobox

hi guys, I’m tryin to make an application using a combobox component, xmlconnector component, dataset and datagrid component. The application should be able to load an xml file choose by the user using a combobox instance on the stage, sounds pretty simple, until I hit the fact that the xmlConnector.url method wouldn’t load the local xml I was trying to load, it keeps saying “Error opening URL” eventhough the trace result of the variable already correct…
can anybody help me?.. I’ve surfed the net and found other people have been asking the same problem, but not an answer, not even the ADOBE/Macromedia people have a clue in their website.
my deadline is approaching, and all I get so far is a headache,:upset:
