Examples with AjaxBehavior javax.faces.component.behavior.AjaxBehavior used on opensource projects

Example 1 with AjaxBehavior

use of javax.faces.component.behavior.AjaxBehavior in project liferay-faces-alloy by liferay.

the class CommandLinkRenderer method processEvent.

    CommandLink commandLink = (CommandLink) componentSystemEvent.getComponent();
    // If the specified event indicates that the command link was added to the component tree, then
    if (componentSystemEvent instanceof PostAddToViewEvent) {

        // presence of a child f:ajax tag.

    } else // Otherwise, the specified event indicates that the command link is about to be rendered. If the ajax
    // attribute is true, then ensure that the AjaxBehavior is rendered. Otherwise, ensure that the AjaxBehavior is
    // not rendered.
