AS3: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::SimpleButton

February 07, 2009

If you get an error like this in an actionscript 3 Flash file:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::SimpleButton@61422481 to [symbolname].
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at classname()[/path_to/as/classname.as:34]

Check the symbol named in [symbolname] to make sure it is specified as a Movie Clip rather than a button.

Other possible reasons for the error are given in:

as 3.0 error #1034

Have you encountered this kind of error in Flex
"Type Coercion failed: cannot convert mx.charts.events::ChartIemEvent to ListEvent"

Thanks

Thanks for the tip. It lead me to my solution. I found that I had a button and a movie clip with the same instance name. I am building a prototype of a user interface and I just put an invisible button on top of a button graphic. I had both named the same thing. The 1034 error message was not very helpful. I supose it would be wise to just add an event listener to the movie clip and skip the invisible button :).
