Icefaces tutorial3/18/2023 ![]() This state (the current index) exists in the UIComponent class but will be maintained by the renderer since it knows when rendering of the current data point has completed and it is time to move on to the next data point. In order to properly render the IDs of the DOM Elements, the iterative renderer must maintain the current index of the data set that is being rendered. Public void decode(FacesContext facesContext, UIComponent uiComponent) If the component is a UIInput, then any new value is extracted from the request and put on the component as the submittedValue. Next, the method ignores all but UIInput components. The first thing the method does is to validate the context and component parameters, checking to ensure that they are not null. This method is responsible for taking any parameters that were passed in from a form post and setting the value on the component. The first method to look at is decode(FacesContext, UIComponent). The encodeBegin and encodeChildren methods do not need to be implemented for this renderer. With a standard component, such as a UIInput with no children, you need only implement the encodeEnd method. This is the encoding of the component which is done in the encode methods of the renderer. The renderer is also responsible for translating a component into a W3C DOM Element. This is the decoding of the component which is done in the decode method of the renderer. The renderer is responsible for processing the form data for the component. The source code for this tutorial is included in the basicInputText sample tutorial application. This tutorial guides you through the process of creating a Direct-to-DOM renderer for a standard component. Creating a Direct-to-DOM Renderer for a Standard UIInput Component ![]()
