Jakob Korherr commented on MYFACES-2618:
----------------------------------------

If you use the JSF 2.0 built-in AJAX mechanism this should not happen, because 
this mechanism only processes necessary components. So I guess you're using 
your own AJAX mechanism, right?

> Don't warn if there is no submitted value in the current request for every 
> EditableValueHolder

> Take a look at HtmlRendererUtils.decodeUIInput(): There we do a check for 
> paramMap.containsKey(clientId) and if this returns false (meaning that there 
> is no submitted value for the given component in the request parameter map) 
> we add a warning message to the log.
> I think we should get rid of this warning, because as a reason of AJAX it is 
> on my opinion normal to not submit all values of a form in every request. 
> Furthermore it has no impact on the lifecycle, because if the submitted value 
> is null it just isn't processed any further.
