Thomas Götz commented on WICKET-2986:
-------------------------------------
I would greatly appreciate that. The usecases you mentioned are exactly what we
are already doing with the feedback messages. Currently we are limited to error
messages though (including metadata) ;-)
> Feedback messages should be String not Serializable.

> Key: WICKET-2986
> URL: https://issues.apache.org/jira/browse/WICKET-2986
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 1.4.10
> Reporter: Maarten Billemont
> Priority: Minor
>
> Component#error currently accepts a Serializable as message parameter. This
> is inconsistent with #info, #fatal and #warn. What's more, Serializable is a
> really bad idea, because a message should always be a String, not a random
> object that can be toString'ed.
> toString is really bad practice for generating messages for user consumption.
> 1. It (generally) bleeds implementation details.
> 2. It (generally) isn't localized and often impossible to localize.
> That also means FeedbackMessage#message should be a String and not a
> Serializable, for the exact same reasons.
