Question

We are working on a project with JSF and PrimeFaces and we are looking to add dynamic inline validation on our forms. I’m not sure if PrimeFaces can handle this (correct me if I am wrong) so I am looking for some alternatives

Does anyone know of any plugins we could use to do this? Prefer something that incorporates JSF too…

I’m not a developer but a UX guy so sorry if some of the terminology is incorrect.

Standard JSF supports server side validation by ajax (live example here) and PrimeFaces definitely also supports it (live example here). You can add <f:ajax event="blur" render="message_id" /> inside input components to perform validation directly on blur (see also this tutorial).

<h:inputText id="foo" value="#{bean.foo}" required="true">
    <f:ajax event="blur" render="foo_message" />
</h:inputText>
<h:message id="foo_message" for="foo" />
