public class FilterForm<T> extends Form<T>
A form with filter-related special functionality for its form components.

This form uses an invisible button to be able to submit when the user presses the ENTER key. If there is a need to add an explicit IFormSubmittingComponent to this form then Form.setDefaultButton(org.apache.wicket.markup.html.form.IFormSubmittingComponent) should be used to specify this custom submitting component.
