[Cayenne-dev] validation exceptions in ROP

Validation exception messages in three tier are pretty unhelpful by
the time they get to the client. We've been extending them by adding
this to ValidationException:


/**
* Returns message that includes the details of the validation
failures.
*/
public String getMessage() {
String message = super.getMessage();
if (result.hasFailures()) {
message = message + " validation failures: ";
for (int i = 0; i < result.getFailures().size(); i++) {
message = message + ((ValidationFailure)
result.getFailures().get(i)).toString();
if (i < result.getFailures().size() - 1) {
message = message + ", ";
}
}
}
return message;
}


Any thoughts about side effects this might have for anyone?


As an aside, what would be even more helpful is if three tier
returned not a CayenneRuntimeException, but a ValidationException to
the client. I don't know if that is hard to change.
