Hmm, {context.root} should have been replaced at compile time by the context root.
 
Are you using mxmlc to compile this on the command line or are you browsing to the .mxml file? If you are using the command line, are you specifying a context root?

Subject: [flexcoders] web services suddenly stopped working!!

I have a very inexplicable problem and I have exhausted everything I know to check, twiddle, verify, etc.  Perhaps someone can think of something else.  My application has a set of webservices that have been working for months.  I have not changed anything related to the deployment environment.  I have not changed the WSDLs.  I have not changed the web services that are called.  When my application starts up it makes a web service call for a list of items.  This particular web service call has been operational for nearly a year.  The only major change I have made is switching over to Flex 1.5, but I did this last week and all of my web services have working up until now.  So I do not see how 1.5 is a factor.
 
Like I stated, when my application launches an initial window comes up and a web service call is invoked.  It looks like the call is never issued by Flex.  I use a tcp monitor and the request never shows.  What I do get is 5 alerts.  All five are completely blank and the title is simply Error.  If I click around blindly at the bottom of the alerts I can find the Ok button and it closes.  But, I have no idea what, if any, message is supposed to be viewable.  I have 5 wsdls so I think the 5 alerts is not coincidental.  However, like I said, they have not changed.  The way I deploy has not changed.  I have no idea what else I can look at or check on.
 
The flashlog shows no problems.  Each WSDL has the following in the flashlog:

The Flex log doesn't show any problems, nor does anything appear in the server console.
 
The method for calling the first service is below.  Everyone of those trace stmts appears in the Flash log, so the method is not blowing up.
 
 public function fetchDSNList() : Object
 {
trace("UserWebServiceImpl - fetchDSNList()");
     var request : XML = new XML();
var root : XMLNode = request.createElement(Constants.DSNLIST_REQUEST_TAG);
var dNode : XMLNode = request.createElement(Constants.LIST_TAG);
var tNode : XMLNode = request.createTextNode("Get List.");
     dNode.appendChild(tNode);
     root.appendChild(dNode);
     request.appendChild(root);
trace("UserWebServiceImpl - calling: " + "FetchDSNList");
trace("UserWebServiceImpl - _userServices: " + _userServices);
     _userServices.FetchDSNList.request = request;  
     var userCall = _userServices.FetchDSNList.send();
trace("UserWebServiceImpl - userCall: " + userCall);
    userCall.resultHandler = mx.utils.Delegate.create(this, fetchDSNListResult);
    userCall.faultHandler  = mx.utils.Delegate.create(this, fetchDSNListFault);
trace("UserWebServiceImpl - creating return call");
    userCall.returnCall = new Object();
trace("UserWebServiceImpl - returning return call");
    return userCall.returnCall;
 }
