Class FileUploadField

All Implemented Interfaces:
Serializable, Iterable<Component>, IEventSink, IEventSource, IFeedbackContributor, IConverterLocator, IGenericComponent<List<FileUpload>,FormComponent<List<FileUpload>>>, IMetadataContext<Serializable,Component>, IFormModelUpdateListener, IFormVisitorParticipant, ILabelProvider<String>, IHeaderContributor, IRequestableComponent, IHierarchical<Component>, IClusterable

Form component that corresponds to a <input type="file">. When a FileInput component is nested in a Form, that has multipart == true, its model is updated with the FileUpload for this component.

NOTEThe model of this component is reset with null at the end of the request because FileUpload instances do not survive across requests since the input streams they point to will be closed. Because of this, the FileUpload instance should be processed within the same request as the form containing it was submitted.
