I'm using Apache Wicket 9. I'm looking at field validations and feedback
messages and I'm wondering how to do this properly:
I've got a form of the nature
<input type="password" wicket:id="field1" label="password"/>
<span wicket:id="feedback">field feedback will be here</span>
<input type="password" wicket:id="field2" label="confirm password"/>
<span wicket:id="feedback">field feedback will be here</span>
<hr>
<span wicket:id="feedback">global feedback will be here</span>
---
ComponentFeedbackMessageFilter:
https://nightlies.apache.org/wicket/guide/9.x/single.html#_displaying_feedback_messages_and_filtering_them
works well for the field feedbacks.
But that supposing that I'm checking that password and confirm password
should match, and if they don't I post an error message in the 'global
feedback' feedback that is for the form.
What would be a good way to do that? As it seemed
ContainerFeedbackMessageFilter would simply include messages from all
the child fields.
I need to flag a ValidationError or FeedbackMessage as 'global' and pass
that such that I can perhaps construct a custom FeedbackMessageFilter to
look for 'global' error messages, e.g. to say that password and confirm
password do not match.
But it'd seem FeedbackMessage passed in public interface
IFeedbackMessageFilter
boolean accept(FeedbackMessage message);
And FeedbackMessage neither contains a link to the original
ValidationError() nor can a custom FeedbackMessage be passed sub-classed
say in ValidationError.setMessage(String message). e.g. that setMessage
uses a custom sub-classed FeedbackMessage instead of a string.
Thanks in advance
