Some troubles with XML-array

[eugene ledak]

Hello, FlexXB Team.

I need to serialize XML-array. And I've got some troubles with it. The array's element is defined as follows

package loggingTools
{
    [XmlClass(alias = "message")]
    [ConstructorArg(reference="timeStamp")]
    [ConstructorArg(reference="item")]
    [ConstructorArg(reference="action")]
    [ConstructorArg(reference="arguments")]
    [ConstructorArg(reference="success")]
    [ConstructorArg(reference="stackTrace")]
    [Bindable]
    public class MessageLog
    {
        [XmlAttribute()]
        public var timeStamp:Date;
       
        [XmlAttribute()]
        public var item:String;
       
        [XmlAttribute()]
        public var action:String;
       
        [XmlAttribute()]
        public var arguments:String;
       
        [XmlAttribute()]
        public var success:Boolean;
       
        [XmlAttribute()]
        public var stackTrace:String;
       
        public function MessageLog(timeStamp:Date, item:String, action:String, arguments:String, success:Boolean, stackTrace:String) {
            this.timeStamp = timeStamp;
            this.item = item;
            this.action = action;
            this.arguments = arguments;
            this.success = success;
           
        }
       
    }
}

It serializes good and I have no problems, while dealing with a single object. But i need an array. Of course, it's possible to serialize all items one by one in loop, but I dislike this idea. Array's definiton is looking in the following way:

package loggingTools
{
    [XmlClass(alias = "Log")]
    [ConstructorArg(reference="timeStamp")]
    [ConstructorArg(reference="testScenarioName")]
    public class TestCaseLog
    {
        [XmlAttribute()]
        public var timeStamp:Date;
       
        [XmlAttribute()]
        public var testScenarioName:String;
       
        [XmlArray(alias = "Log", type="loggingTools.MessageLog")]
        [ArrayElementType("loggingTools.MessageLog")]
        public var messages:Array;
       
        public function TestCaseLog(timeStamp:Date, testScenarioName:String)
        {
            this.timeStamp = timeStamp;
            this.testScenarioName = testScenarioName;
            messages = new Array();
        }
       
        /**
         * Adds a message to the log
         * @param control -- tested control
         * @param arguments -- action's params (if any)
         * @param stackTrace -- stack trace (if any)
         *
         **/
        public function addMessage(timeStamp:Date, control:String, action:String, arguments:String, success:Boolean, stackTrace:String):void {
            var testMessage:MessageLog = new MessageLog(timeStamp, control, action, arguments, success, stackTrace);
            messages.push(testMessage);
        }
    }
}

And I try to serialize it with the following code:

package loggingTools
{
    import com.googlecode.flexxb.FlexXBEngine;

    //import com.googlecode.flexxb.serializer.BaseSerializer;
   
    public class PlainXMLLogger
    {
        private var logFile:XML;
        public var logData:TestCaseLog;
....
....

        public function close():void {
            // TODO: uncomment
           
            var logXML:XML = FlexXBEngine.instance.serialize(logData.messages);
           
            trace(">> XML LOG ");
            trace(logXML.toString() );
           
                   
        }
}

'serialize()' method raises an exception. 'logData' object is created and isn't null yet. It's 'messages' member contains 70 elements.

The exception's call stack is
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Could you tell me, how can I solve this problem?

Hello Eugene,

I see that in the close method you have the following line:

var logXML:XML = FlexXBEngine.instance.serialize(logData.messages);

Did you try with serializing the logData itself? I will runt a quick
test with the config you sent and see how it goes.

Thank you, your advise was a very helpful. FlexXB created a file, which is looking in the following way:

<Log timeStamp="Tue Apr 10 16:09:37 GMT+0300 2012" testScenarioName="LOC_Locations_CRUD">
  <Log>
    <message item="Pause: 10000" arguments="" timeStamp="Tue Apr 10 16:10:28 GMT+0300 2012" stackTrace="" success="false" action=""/>
    <message item="SelectText: textInputName" arguments="" timeStamp="Tue Apr 10 16:10:28 GMT+0300 2012" stackTrace="" success="false" action=""/>
    ....
  </Log>
</Log>

It's nice. But can you give me a little hint about how to remove this blue tag?

[Alexutz]

Try setting alias to "*" for the messages array

Thanks, again :)
