Adrian Tarau commented on VELOCITY-467:
---------------------------------------
However, I'm still convinced that in this case(and maybe some other cases) I
would like to be informed when a wrong object is passed to a #foreach. I agree,
this should be done on the application side, your code should be protected for
this kind of "failures" - passing wrong types.
Of course, some logging/listeners which can provide support for the application
to distinguish and take action for this kind of "problems" would be preferable.
I would really love to see that happening in 1.7.
> Throw more exceptions and log less errors

> Key: VELOCITY-467
> URL: https://issues.apache.org/jira/browse/VELOCITY-467
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.5 beta1
> Reporter: Will Glass-Husain
> Priority: Minor
> Fix For: 1.6
>
>
> Now that Velocity application exceptions are based on RuntimeException, we
> have more opportunity to use exceptions to signal application level problems.
> I'm particularly concerned about initialization problems that are logged and
> may be missed. We need to review all logged error messages and see if it
> would be more appropriate to throw an exception instead. Some of these
> places we may need to leave as is for backwards compatibility reasons. (e.g.
> macro in the global macro library doesn't parse properly).
> Llewellyn Falco made a good case for this on the dev list recently:

> I still would like to put in my vote that sending error's to the log is an
> incredibly BAD idea.
> If something is not working, it should be LOUDLY shown as an exception.
> If it is working I don't really need a log.
> The (velocity) log should be there for velocity developers (those programming
> the actual velocity code) not users.
> I don't ever care to see tomcat's log, I care to see the things I log while
> in tomcat.
> Most of all, many many many people do not check the log at all, let alone
> frequently.
