>          Components: wicket
>    Affects Versions: 1.4.10

> 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.
