Taher,
I think you misunderstood what Scott said. What I understood is he was speaking about the 1st block of code in ModelService.validate() which ends with
a return.
I agreed that this clock of code is not needed in isValid() and removed it in
my proposition.
Because isValid() does not makes sense to be called with a context with a
RESPONSE_MESSAGE which could be RESPOND_ERROR or RESPOND_FAIL.
You should simply call isValid() with IN parameters to validate the service and
its context before calling the service with this context.
BTW maybe I should make this more clear in the Javadoc?
So it's not about returning a response message and a boolean perfectly fits
there. Scott please confirm.
Thanks
Jacques

I tend to also prefer a response message. Adding something new like a
boolean flag puts more information for people to process needlessly. Less
is more I think.

Yes, I wondered about that.
In my case the following simplified code would work, because it's used
before running the service.
I guess it's how it should be used (why running isValid() before
running?). So I guess we can simply use that
public boolean isValid(Map<String, Object> context, String mode,
Locale locale) {
try {
validate(context, mode, locale);
} catch (ServiceValidationException e) {
return false;
}
return true;
}
Other opinions?

I guess it depends on how this will be used but I think there is a big
difference between " // do not validate results with errors" and returning
false from an isValid method. IMO an error output response is perfectly
valid.

Log:
Implemented: Add a isValid() method to the ModelService class
(OFBIZ-9158)
The idea is to use validate() to render a boolean result. I needed that
in
a
custom project, I think it's worth contributing.
