Re: highlight invalid fields with custom Validation Framework?
Martin,
Thank you so much. I was exactly in the position where delta458 was and
almost got through with it.
After following your suggestions, the ValidationMsgBehavior looks like this:
pre
public class ValidationMsgBehavior extends Behavior
{
@Override
public void onRendered(Component c)
{
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {
error =
fc.getFeedbackMessages().first(FeedbackMessage.ERROR).toString();
} else {
error = Your input is invalid.;
}
fc.getResponse().write(
div class=\validationErrorMessage\ + error +
/div);
}
}
}
/pre
I'm using Wicket 6.3.0 and there is no onRendered method in Behavior.
I should be using afterRender(Component component) now, right?
That will make this code compatible with the latest wicket version.

Or you may use the default registered converter to transform it to

2) Do you know any good wicket tutorials/example where I can learn how to

The source code is the best. It is really simple.

Re: highlight invalid fields with custom Validation Framework?
Hi,
are you looking for a generic way to highlight invalid components? If
so, have a look at
https://code.google.com/p/londonwicket/downloads/detail?name=LondonWicket-FormsWithFlair.pdf
as an inspiration point. Depending on the wicket version, you might
have to adopt the code a bit.
Hope that helps

Hello,
How can I highlight my form fields when I use a custom validation framework.
The validation process itself is already working. I am using Oval Validation

FormInvoice form = new Form(inputForm, formModel) {

if (violations.size() 0) {

}
}

form.add(new TextFieldString(Empfänger));
form.add(new TextFieldString(Details));
...
Code of HTML File:
It would be great if you give me a short example on how to do that. Or links
with good tutorials?

Since RequiredBorder is a behavior, you can just #add() it.
c.add(new ValidationMsgBehavior());
c.add(new ErrorHighlightBehavior());
}

return *IVisitor.CONTINUE_TRAVERSAL*;
IVisitor has been improved for Wicket 1.5.0.
Example:
new IVisitorComponent, Void()
{
public void component(final Component component, final
IVisitVoid visit)
{
add(component);
visit.dontGoDeeper();
}
});
I.e. you need to use visit#XYZ methods to stop the visitor. Don't call
anything and it will continue.
}
private class RequiredBorder extends BorderBehavior {
public void renderAfter(Component component) {
FormComponent fc = (FormComponent) component;
if (fc.isRequired()) {
super.afterRender(component);
}
}
}
*//AbstractBehaviour could not be found*
private class ValidationMsgBehavior extends *AbstractBehavior* {
AbstractBehavior is renamed to Behavior.
public void onRendered(Component c) {
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {

private class ErrorHighlightBehavior extends *AbstractBehavior* {
public void onComponentTag(Component c, ComponentTag tag) {
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
tag.put(class, error);
}
}
}
}
You face all these problems because you migrate code from version X to
version X + Y, where Y is 1, i.e. you need to read the migration
guides for all the steps.
Or just ask here and we will try to help you :-)
