Is it okay to leave a controller without a view?

You call this controller using AJAX? Or what exactly do you do?

If you call it using AJAX, then it's fine if it does only return a blank page, no ones gonna see it anyway.
You don't have to use a view file, but as soon as you want to display content it's appropriate to do so, as a bunch of echo commands are pretty ugly xD
