Display offenses in the combo box

In this section you will add code to connect to a web service that contains the list of offenses (Forgot to Water Your Plants, and so on). The web service description language (WSDL) file is located at www.flash-mx.com/mm/firstapp/problems.cfc?WSDL. To see how the WSDL is structured, browse to the WSDL location.

The ActionScript code passes the web service results to the ComboBox instance for display. A function sorts the offenses in order of severity. If no result is returned from the web service (for example, if the service is down, or the function isn't found), an error message appears in the Output panel.

In the Actions panel, add the following code:

/* Define the web service used to retrieve an array of problems.
This service will be bound to the problems_cb ComboBox instance. */
var problemService:WebService = new WebService("http://www.flash-mx.com/mm/firstapp/problems.cfc?WSDL");
var myProblems:Object = problemService.getProblems();

/* If you get a result from the web service, set the field that will be used for the column label.
Set the data provider to the results returned from the web service. */
myProblems.onResult = function(wsdlResults:Array) {
    problems_cb.labelField = "name";
    problems_cb.dataProvider = wsdlResults.sortOn("severity", Array.NUMERIC);
};

/* If you are unable to connect to the remote web service, display the 
error messages in the Output panel. */
myProblems.onFault = function(error:Object) {
    trace("error:");
    for (var prop in error) {
        trace("  "+prop+" -> "+error[prop]);
    }
};

TIP

Press Control+S to save your work and then Control+Enter (or select Control > Test Movie) to test the application. The combo box should be populated with a list of offenses at this point and you should see the empty data grid that you created for Gift Ideas, along with the checkout button.
