I did this with an IVisitor, that traverses all form components and adds an
AbstractBehavior to each required inputfield. This Behavior writes an
span*/span right after the component has been painted.
Watch this pdf for an example:
http://code.google.com/p/londonwicket/downloads/list and than
LondonWicket-FormsWithFlair.pdf
As setComponentBorder is deprecated in newer wicket versions i left the
componentBorder part out, no need for it.
For making it work with ajax, i had also to implement
AbstractBehavior.isTemporary()
and to add the forms parent as a target oft he calling button

Subject: Easier using of FormComponentFeedbackIndicator for many fields?!
Hi Folks,
i've to implement many form-pages with a lot of (more than 30) input fields,
and each of them should be validated at least of required or not.
but the request is to show the validation-errors behind the depeding
component.. so iam using FormComponentFeedbackIndicator now and everything
works fine with:
searchfield = new RequiredTextFieldString(seachfield, new
PropertyModelString(SearchPanel.this, searchString));
add(searchfield);
indicator = new FormComponentFeedbackIndicator(searchfield_indicator);
indicator.setIndicatorFor(searchfield);
indicator.setOutputMarkupId(true);
indicator.setOutputMarkupPlaceholderTag(true);
add(indicator);
this is an ajax-form so i have to add this to onSubmit too for each
validating field.
protected void onError(AjaxRequestTarget target, Form? form) {
target.addComponent(indicator);
}
Is there any Hint to easier this implementation?
What i imagine is something like:
searchfield = new *RequiredValidatedTextField*String(seachfield, new
PropertyModelString(SearchPanel.this, searchString));
and inside this child class iam building a indicator
but how could i add the indicator-Span dynamically to the markup and how
could i do the target.addComponent than?
Thanks for any hints.
