[FIX] when switching between actions like a madman, there seem to be cases when a search view *should* be ready (on_loaded has finished executing) yet not all widgets are fully rendered (has only happened on the Date one so far, YMMV)

just raise an invalid search error instead of blowing up, I can't find what the actual problem is for now
