TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@64e6ca1 to fla

[Zainuu]

Hi all,

I'm getting this error pop-out window when I pressed on a button. The button listener contains the following code:

btn_start.addEventListener(MouseEvent.CLICK, gotoStart);
function gotoStart(e:MouseEvent):void{ 
     btn_start.removeEventListener(MouseEvent.CLICK, gotoStart);
     gotoAndStop("START");
}

TypeError: Error #1034: Type Coercion fai led: cannot convert flash.display::MovieClip@64e6ca1 to flash.display.SimpleButton

at flash.display::MovieClip/gotoAndStop()

at attendanceCheck/gotoStart()[attendanceCheck::frame2:31]

After searching for the cause for a while, I can't find what is wrong with it...

Help me please...

Thanks,

Zainuu

There is nothing wrong with that code, so if there is a problem with it, it might be due to something else in the file.  Since you show the error message in two pieces it gives the impression you are not showing the entire error message, as though you left out a middle section.  If so, the start of the missing section is where you are likely to find the true error indication.

Hi Ned Murphy,

That is the entire error msg. Sorry for the wrong impression... I have other buttons going to other frames which does not gives me any errors. But for the button that brings me to frame "START", it gives me that error.

As I said, there is nothing wrong with that code.  So since the error is indicating you are trying to treat a MovieClip as if it is a SimpleButton, somewhere in your design you have done something to attempt to coerce that MovieClip into being a Button (or possibly vice versa if it is actually a Button).  Check the properties panel and elsewhere to see if you have selected something that would be trying to make that button a different type of object than what it is.

Try creating a new movieclip and assign it that name (removing it from the other) and see if you still get the error.  If that works, then I recommend just creating a new movieclip and replacing it for the current one that is giving you the problem.

Thnaks for this, Ned. i was getting the same # 1034 error, which was happening inconsistently, i.e. sometimes yes, sometimes no error. i realized i was using an instance name of play_btn when in fact, that was for a MovieClip and not a simple button. So i fixed the code and instance name to reflect the MovieClip. I think the issue's been fixed.
