If you're index page is supposed to render something and the
parameters are all wrong then you can return a 404 from there. The
strategy that I'm using is to gather up all my parameters in specific
onActivate methods and then the empty param onActivate checks the
context and returns 404 if it's not valid.
Object onActivate() {
if ( !isValidContext() ) {
return new ErrorCode(404, "The requested page was not found");
}
return null;
}
The code for implementing ErrorCode can be found in the archives of this list.
