Tag commandButton


Renders an HTML "input" element. <br /> During Decoding: Obtains the Map from the "requestParameterMap" property of the ExternalContext. If the value in the Map for the value of the "clientId" property of the component is not null, create a javax.faces.event.ActionEvent around the component, and pass it to the queueEvent() method of the component. If the request is Ajax-performed, add its target IDs of the reRender property to the rendered areas list of the nesting AjaxContainer. <br /> During Encoding: Builds an AJAX.Submit JavaScript call for the "onclick" event. Renders the clientId of the component as the value of the "name" attribute. Renders the current value of the component as the value of the "value" attribute. If the "styleClass" attribute is specified, render its value as the value of the "class" attribute. Renders child components inside the HTML "input" element.
