JSF 2.x Tip of the Day: RichFaces Programmatically Creating an <a4j:commandLink/>

This example of how to create an <a4j:commandLink/> uses another library called jsf-utils to handle the heavy lifting.

The method below will create the <a4j:commandLink/> component, any additional configuration will need to be performed programmatically, or using the tag attributes.

public UICommandLink createUICommandLink(final FacesContext context, final String value, final String render, final String methodExpression) {     Class<?>[] clazz = new Class<?>[]{};     UICommandLink link = (UICommandLink) context.getApplication().createComponent(UICommandLink.COMPONENT_TYPE);     link.setValue(value);     link.setRender(render);     link.setActionExpression(JSFUtils.createMethodExpression(methodExpression, String.class, clazz));     return link; }

You would bind it to a backing bean to a UICommandLink component;
