WICKET-6482 delegate to nested behaviors
> CompoundValidator should implement all Behavior methods
> -------------------------------------------------------

> Key: WICKET-6482
> URL: https://issues.apache.org/jira/browse/WICKET-6482
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 7.8.0
> Reporter: Sven Ackermann
>
> Hi,
> I recently had an issue with a {{CompoundValidator}} using a
> {{StringValidator}} inside.
> The problem was that the {{TextField}} which had the validator assigned did
> not have a "maxlength" attribute in its HTML representation. Normally
> {{StringValidator}} outputs this attribute automatically when the maximum is
> not null and the HTML field is of type "input". This is handled in
> {{StringValidator.onComponentTag}}.
> Unfortunately, {{CompoundValidator}} does not delegate its own
> {{onComponentTag}} method to the contained validators, so the
> {{onComponentTag}} method of the included {{StringValidator}} is never called.
> I think, all {{Behavior}} methods should be implemented by
> {{CompoundValidator}} to delegate to the contained validators because this is
> the expected behavior.
> For {{onComponentTag}} it could look like this:
> {code:java}
> @Override
> public void onComponentTag(Component component, ComponentTag tag) {
> for (IValidator<T> validator : validators) {
> if (validator instanceof Behavior) {
> Behavior behavior = (Behavior) validator;
> behavior.onComponentTag(component, tag);
> }
> }
> }
> {code}
