Huge problem when testing flash app in browser

something weird is going on. i am developing a website and when i test the movie on the flash IDE it works just fine, it also works on the standalone flashplayer.

the problem im having is that when on the browser, plugin or ActiveX players it throws errors like this

Property registerEventListener not found on app.projects.Projects_Model and there is no default value.

i know everything is there because it works on when i test it… but it seems that it cannot find the **registerEventListener **method from the inherited class

inheritance is as follows

EventBroadcaster which contains the [public function registerEventListene]
BaseModel
ProjectsModel

is this a bug in the flash player or am i missing something ??

thanks
