PrimeFaces - Set a JSF component as mandatory

I am using PrimeFaces and JSF - I need to be able to set a component on the page as mandatory in response to an AJAX event. Is the best way to accomplish this using the following code or is there also a way to accomplish it using JQuery ?

Thanks

UIInput componentToChange = (UIInput)  facesContext.getViewRoot().findComponent("ComponentId");
componentToChange.setRequired(true);

Thanks

Just set the component's required attribute with the desired EL expression.

E.g.

<h:inputText ... required="#{bean.required}" />

There are even EL ways without needing an additional bean property, but it's impossible to propose one based on the sparse information provided so far.

Use findComponent() with care. Think twice if it really can't be done just in the view (XHTML) side.
