org.apache.wicket.protocol.http.MultipartFormComponentListener

All Implemented Interfaces:

AjaxRequestTarget.IListener

public class MultipartFormComponentListener
extends Object
implements AjaxRequestTarget.IListener

This listener updates the Form's enctype whenever a multipart FormComponent is added to the AjaxRequestTarget. This is needed because the multipart form component may change its visibility/enablement and thus change the multipart-ness of the whole form.
