Examples of org.apache.wicket.validation.ValidationError

org.apache.wicket.validation.ValidationError
A versatile implementation of {@link IValidationError} that supports message resolution from{@link IErrorMessageSource}, default message (if none of the keys matched), and variable substitution. The final error message is constructed via the following process:
1. Try all keys added by calls to {@link #addKey(String)} via the providedIErrorMessageSource.
2. If none of the keys yielded a message, use the message set by {@link #setMessage(String)}, if any.
3. Perform variable substitution on the message, if any.
