    (Very) weird error involving classes and loaded SWF

    I had the following problem in my project:

    My project is about a header.swf that calls a nav.swf (with a menu and other stuff) and also inits a slideshow through a Slideshow class.

    This is in header.swf:

    Code:
    		private function topLoaderHandler(e:Event):void
    		{
    			topContainer = e.target.content;  // nav.swf is the loaded swf
    			topContainer.y = 10;
    //			topContainer.x = (stage.width - topContainer.width) /2;
    			addChild(topContainer);
    			
    			new XmlParser("xml/slides.xml").addEventListener("XML_PARSED", initSlideShow);
    		}
    		
            private function initSlideShow(e:Event):void
            {
    			slideshow = new Slideshow(e.target.myXML, 5000, 2, 0);
    			// xml, delay, fade, delayBetween
    			
    			slideshow.addEventListener("LOADING_START", onStartLoading);
    			slideshow.addEventListener("LOADING_COMPLETE", onCompleteLoading);
    			slideshow.addEventListener("FIRST_IMAGE_LOADED", startAnimation);
    
    			slideshow.start();
    	
    			ss_container.addChild(slideshow);
            }
    The slideshows loads correctly but the nav doesn´t show.
    I tried lot of things and then discovered that if I remove the line
    " new XmlParser("xml/slides.xml").addEventListener("XML_PARSED", initSlideShow);", the nav.swf would show perfectly.

    So what did I do ?

    I renamed the XmlParser class to "XmlParser2.as" (as well as other references to it) and then...it worked !!!

    what the hell was going on here?

    obs: I tried that also: I commented all the code inside the "initSlideShow" function, keeping the XmlParser instantiation, and the nav.swf didn´t show as well.

    obs2 : i didn´t had XmlParser.as imported cause it was in the root directory. ( i explicitely imported it and tried to compile but same thing happened)

    obs3: nav.swf uses the XmlParser.as to load two menus, however I don´t believe it has anything to do it since it´s a file that is already compiled, at the point I try to load it into header.swf, right?

    Well I luckely solved the problem in about one hour but i would like to know was that all about . I got no clue.
    Thanks a lot !

    Why aren't you assigning the new XmlParser to a var? I'm guessing because you're doing the loading inside the constructor? IMO not a good idea.

    Also, when you're loading an external swf, it's usually enough to just add the loader() object you're using.

    PHP Code:

    var l:Loader = new Loader();
    l.load(new URLRequest("nav.swf"));

    topContainer.addChild(l);

    var 
    xp:XmlParser = new XmlParser("xmlfile.xml");
    xp.addEventListener("XML_PARSED"init);

    //etc 
    I (Love | Hate) Flash.

    Save a version back so others may help you!

    I tried that - assigning the new XmlParser to a var and then adding the listener in a new statement. it didn´t change anything.

    is that a bad practice to do it the way I did ?

    I didn´t try to add just the loader instead of "e.target.content".... what´s the difference ? I´ll try that. Though I don´t think that will solve the problem.

    cause I actually solved the problem in a very strange way (renaming the class). it was really intriguing for me. i don´t know if I explained it clearly...

    thanks!
