why are the keys contained in the state if the thing is null? null is the default value, we should probably not state save this case. Same with the default values of valid and localValueSet... best regards, Martin > On Fri, Jul 23, 2010 at 6:07 AM, Martin Marinschek <mmarinsc...@apache.org> > wrote: >> >> Hi guys, >> >> >> > Unfortunately, try to save the state directly on the child components is >> > not >> > possible.
