There should always be a submitted value for an input if it is rendered, its form is submitted, and it is not disabled or read-only.
This is a difference from JSF-RI that does not process input is no value is submitted without any warning (i.e. it is recognized as a normal behavior). It happens when you use ajaxSingle attribute directly or one of the component (suggestionbox, simpleTogglePanel etc) works in this mode.
You can limit the processing part of the component tree with <a4j:region> tag.
