[Wicket-user] Validations

[Manuel Corrales]

Hi, here i go, for my third question of the day (Thats the bad thing of a real nice community, one can get dense asking :)).

I have a form and i added some RequiredTextFileds, if i understand correctly, if i do not enter data on that field, an error should appear on a feedback or something like that??
The thing is that i get an exception:

Caused by: java.util.MissingResourceException: Unable to find resource: RequiredValidator


i am missing something? How can i set the error message displayed?

Sorry for so much questions.
