The ampersand is causing a problem. Try doing & in the url string instead in your MXML. If you do it programmatically in a Script block you'll need to have a CDATA block in there.
<mx:Script> <![[CDATA ]]> </mx:Script> Matt -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Raheen M Shabbazz Sent: Sunday, January 22, 2006 1:02 PM To: [email protected] Subject: [flexcoders] Re: HTTPService -- Generic error code Thanks for all your continued help. The service returns the image itself and, based on your recommendation, I have been trying to simply set the source of the image to the URL of the service. When I do this, however, very strange things begin to happen. In the validator, I get an XML error for any variable past the first encoded variable in the URL string. So, for example, if I try to set the source to "http://www.mydomain.com/services?var1=val1&var2=val2&var3=val3";, I will get validaton errors for var2 and var3 that say "undetermined entity reference [XML]" and "entry Var2 was not found [XML]". If I ignore these errors and run the app, I get the following error: "The reference to entity "var2" must end with the ';' delimiter." Is there a proper way to embed these parameters into the URL that I'm missing? I even tried to build a URL string and programmatically set the image source to the URL string -- but that gave me the same errors as well.
