1. This, "url="url"" is wrong. What are you expecting form an URL
that is the string "url"? Are you attempting to bind the url property
to a variable?
2. If so, then do url="{_url}". ( and don't use a property name
for a variable name.) But that will require the var _url be declared as
an instance variable.
3. In your combo click handler, assign the url string to the
instance variable, not to a local variable.
Actually my preference would be to assign the url directly in the
handler, instead of binding:
var sURL:String = "http://localhost/cgi-bin/dbRecords.cgi?ini="; + ini;
trace("sURL=" + sURL); //copy and paste this into a browser to test it.
dbRecords.url = sURL;

Subject: [flexcoders] Multi Query HTTPService Functions Variables
DataGrid. Error with 2nd URL query
Hi,
Im trying to get this app working. currently Working it query's the
database with <mx:XML> and populates <mx:ComboBox> on the selection
is captures the user selection. Here on out Im having issues.
I need to pass the variables through a url so I bound the comobox
selection to a variable and then the new URL to a variable with the
combobox selection + added on.
It then connects to the new Url with <mx:HTTPService> and populates a
datagrid with the return XML from the Http request.
my code complies with no problems but when run it errors out
at
mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal:
<http://www.adobe.com/2006/flex/mx/internal:>

The inital query to a URL works and populates a combox im unsure what
is exactly wrong with my code. I have been staring at it for about 2
days now have issues. I found this website that helped.
