You are correct, the formsValidationChange event is bound for the
formvalid property of the component.

[ChangeEvent("formValidChanged")]
public function get formValid():Boolean
{
      return _formValid;
}
           
public function set formValid( formValid:Boolean ):void
{
      setFormValid( formValid );
}

private function setFormValid( formValid:Boolean ):void
{
      if ( formValid != _formValid )
      {
            _formValid = formValid;
            dispatchEvent(new Event("formValidChanged"));
      }
}


I've put Alerts in the formsValid function and it's getting to the
function, but it doesn't seem to be recieving the
"formValidationChange" event everytime it's set to a new value. I'm at
a loss...

If I don't use a state and put in this button on the page initially
all is good.
