as 3.0 error #1034

im getting the following error on the output window, although the .swf file works just fine when tested and published.

menu
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1e878881 to flash.display.SimpleButton.

this is the code that is generating the error:

apps.addEventListener(MouseEvent.CLICK, clickapps);
function clickapps(event:Event):void{
trace("apps");
gotoAndStop("apps");
}
entrees.addEventListener(MouseEvent.CLICK, clickentrees);
function clickentrees(event:Event):void{
trace("entrees");
gotoAndStop("entrees");


any ideas?
thanks,

}

Are you sure it is that code? There is nothing wrong with the code, which should give such error. You would only get this error if you cast a SimpleButton object to a MovieClip.

I am trying to create a sub-menu within the main time line ( a website for a restaurant). under the Scene 1, there is a tab menu with the following code:

home.addEventListener(MouseEvent.CLICK, clickhome);
function clickhome(event:Event):void{
trace("home");
gotoAndStop("home");
}
menu.addEventListener(MouseEvent.CLICK, clickmenu);
function clickmenu(event:Event):void{
trace("menu");
gotoAndStop("menu");
}
reviews.addEventListener(MouseEvent.CLICK, clickreviews);
function clickreviews(event:Event):void{
trace("reviews");
gotoAndStop("reviews");
}
catering.addEventListener(MouseEvent.CLICK, clickcatering);
function clickcatering(event:Event):void{
trace("catering");
gotoAndStop("catering");
}
hosts.addEventListener(MouseEvent.CLICK, clickhosts);
function clickhosts(event:Event):void{
trace("hosts");
gotoAndStop("hosts");
}
photos.addEventListener(MouseEvent.CLICK, clickphotos);
function clickphotos(event:Event):void{
trace("photos");
gotoAndStop("photos");
}
contact.addEventListener(MouseEvent.CLICK, clickcontact);
function clickcontact(event:Event):void{
trace("contact");
gotoAndStop("contact");
}

under the "menu" tab, i pretty much recreated a smaller version of the main tab menu to contain the appetizers, entrees, etc.. the script for that menu is as following:

apps.addEventListener(MouseEvent.CLICK, clickapps);
function clickapps(event:Event):void{
trace("apps");
gotoAndStop("apps");
}
entrees.addEventListener(MouseEvent.CLICK, clickentrees);
function clickentrees(event:Event):void{
trace("entrees");
gotoAndStop("entrees");
}

when i run the movie, and click on the "entrees" tab the following error occurs:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1ce882e1 to flash.display.SimpleButton.

When i click on the "apps" tab, the following two erros occur:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at barcelona_fla::MainTimeline/barcelona_fla::frame10()
entrees
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1ce882e1 to flash.display.SimpleButton.

both buttons have the appropriate instance names, and the navigation is correct when tested or exported as .swf, i just can't figure out the errors. any ideas?
thank again

Have a look at your timeline and make sure there is only one keyframe... ie your frames look continuous and there's no gaps or key frames breaking up things.

I've just had the same problem myself. A bit of detective work revealed that it has nothing to do with the code, but occurs when:

• The swf is being run from a remote server.
• You have a custom class on the stage which has an instance name.
• The class is NOT declared as "Export in first frame".
• An instance of the class doesn't appear on the first frame of the movie.

So the solution, in my case, was just to tick "Export in first frame" in the library symbol linkage options. This made everything work fine, but if anyone knows why this is then I'd be interested to know.

Just to get past the error you can use the wildcard * when you declare your variable.

var mc:*

Probably not best practice but it worked for me.
