My solution is put this in action method like you say, but i have a lot of relationships in the client, with address, sex, etc... i think this give a lot of work and make my code ugly.... That why i say that ognl null handler thats ww use is cool if getAddress return null he instanciates a new one the time i need, so if no address was typed no address is create, that saomething like that in EL???
