I have a button that submits my page and I want some fiels to be validated at this time but other field need to be validatet later on.

Another choice could be the use of ajax (I suggest ajax4jsf). Maybe, but not sure about it, could be usefull also the "immediate" property (it is in every UICommand and EditableValueHolder component).
