(Very) weird error involving classes and loaded SWF

[ziriguidum]

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:

		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 !
