I don't have the info in front of me, but I remember reading something about validators that are composed of other validators. So if you have two validators A and B. You can define a third 'C' which is composed of the other two.
Hunt through the doco, you should find it.
After further research, it appears that there is no known solution to obtain a ConstraintValidator instance for a given constraint, portable or not. A helper class seems to be the only way to do this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
