Description
FormComponentFeedbackIndicator is not work. FormComponentFeedbackIndicator always invisible because:
first render forms contain no errors,
method FormComponentFeedbackIndicator.onBeforeRender (line 78) sets component invisible.
onBeforeRender() not call for invisible components.
workaround: override isVisible method :
@Override
public boolean isVisible()
method onBeforeRender don't need override in org.apache.wicket.markup.html.form.validation.FormComponentFeedbackIndicator
same situation with FormComponentFeedbackBorder .
