You need a 'return' before the recursive call:
class com.research.StaticRecurse
{
public static function
getOuterMostParent(mc:MovieClip,mcRoot:MovieClip):MovieClip
{
if (mc._parent._name == "garden")
{
trace("inside getOuterMostParent: " + mc);
return mc;
}
else
{
// Add a return here:
return getOuterMostParent(mc._parent);
}
}
}
