Re: Ajax validation error messages
Why not just put a filter on your 'global' feedbackpanel and filter out
the messages that you already display for each component? E.g. I have
the following code in a form:
private void addGlobalSubmitPanel() {
final List components = getFormComponents();
final FeedbackPanel feedback = new FeedbackPanel(FEEDBACK);
feedback.setFilter(new IFeedbackMessageFilter() {
public boolean accept(FeedbackMessage message) {
return !components.contains(message.getReporter());
}
});
add(feedback);
}
private List getFormComponents() {
final List components = new
ArrayList();
visitFormComponents(new FormComponent.IVisitor() {
public Object formComponent(IFormVisitorParticipant
formComponent) {
final FormComponent fc = (FormComponent)formComponent;
components.add(fc);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return components;
}

Re: Ajax validation error messages
May be you can use AjaxFormSubmitBehavior? steve222 wrote: > > Hi.

Ajax validation error messages
Hi. Can anyone recommend a good strategy for handling and dislplaying validation error messages when using Ajax? I want my basic field validation error to show next to the relevant input text boxes, and have used my own FormComponentFeedbackBorder to do this. I still want a feedback panel for more fatal backend errors - eg, "record already exists", "concurrent record modification", etc. Problem. If I put a feedback panel on the page, and repaint this in my button's onError with target.addComponent(feedback) - then I get duplicates of my field validation errors in my panel. Not what I want. If I only repaint the feedback onSubmit then I can catch the backend error and display my message. But subsequent Ajax form submissions don't refresh the page, so the error message in the feedback panel "sticks" on the page. Not sure how to clear out existing errors in the feedback panel when using Ajax, so have now used a label on my page instead, and manually clean up after myself. But is this the best way to go? -- View this message in context: http://www.nabble.com/Ajax-validation-error-messages-tp19190006p19190006.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
