Is your "system" object already in a DataContext (in the alterSystem() method)?
If "system" is already in a DataContext, you don't need to call DataContext.registeredObject(), because it is in your data context already. If "system" is NOT in a DataContext, all of your set methods (setNamSystem(), setSglSystem(), etc) will cause Cayenne to be unaware of those changes, so when you commit, Cayenne thinks they are clean and does nothing.
I'm not certain, but if "system" is in your DataContext and then you call registeredObject(), I suspect it'll discard all of your changes, but again, I'm not certain of that.

Tks Gentry,
But i have set the values of object in another class, its affect the object to persist?
Follow the method whith sets:
public String alterSystem(String nome, String sigla, String apelido, String versao, Short licencas, String nomeLicenca, boolean pacote, boolean codigoFonte){
//Cria as variaveis para gravação.
FindLicence findLicence = new FindLicence();
//Preenche os dados para cadastro.
system.setNamSystem(nome);
system.setSglSystem(sigla);
system.setNamAliasSystem(apelido);
system.setDscVersion(versao);
system.setQtdLicences(licencas);
//Carrega a Licença informada.
Licence licence = null;
if(nameLicence != null) licenca = findLicence.searchLicence(nameLicence);
//Preenche Pacote e Codigo Fonte
String strPack = null, strFont = null;
if(pack == true) strPack = "Y"; else strPack = "N";
if(font == true) strFont = "Y"; else strFont = "N";
sistema.setIndPack(strPack);
sistema.setIndFont(strFont);
//Valida informações informadas.
if(system.updateSystem(system) == false) {
String msgErr = new String("Error.");
return msgErr;
}
return null;
}
Tks,
Reinaldo.

Well, since you haven't edited the object, I wouldn't expect Cayenne to save anything, even if the original object in the database has "invalid" data. I would expect the validation routines to only be called for objects that have been edited and need to be saved. Also, keep in mind that if an object has a firstName of "frank" and you do a setFirstName("frank") on it, Cayenne is smart enough to know that the object didn't really change and it will not be flagged as dirty/edited, so nothing would be saved to the database on commit.
Hope that helps!

I´ve a update but this update don´t generate error, and don´t commit information, follow my code:
public boolean updateSystem(Sys system){
try{
con.registeredObject(system.getObjectId());
con.setValidatingObjectsOnCommit(true);
con.commitChanges();
return true;
}
catch(Exception e){
con.rollbackChanges();
return false;
}
}
Tanks,
Reinaldo.
