UIInput and UIOutput Tags
UIInput and UIOutput Tags
An editable text component in a JavaServer Faces application is represented by a UIInput
component. One example is a text field. A read-only text component in a JavaServer Faces
application is represented by a UIOutput component. One example is a label.
The UIInput and UIOutput components can each be rendered in four ways to display more
specialized text components.
lists all the renderers of UIInput and UIOutput and the
tags that represent the component and renderer combination. Recall from
that the name of a tag is composed of the name of the
component and the name of the renderer. For example, the inputText tag refers to a UIInput
component that is rendered with the Text renderer.

The UIInput component tags support the following tag attributes in addition to those described
at the beginning of
. This list does not include all the attributes supported by the UIInput component tags,
just those that page authors will use most often. Please refer to the html_basic.tld file for the
complete list.

for more information on how to use this
