I think I got it. if I will use | <s:validateAll> | <h:inputText ... | <f:validateLength minimum="0" maximum="100" /> | </h:inputText> | </s:validateAll> | It will break hibernate validation. You can assume that f:validateLength does not need to be there, but what other validators, are they valid with hibernate validation?
