render="@none" works incorrectly with ajaxRendered="true"

[agori]

As far as I know, the default value for render attribute is @none. If render is @none, no ajaxRendered component is rendered after an AJAX request. Worse, rich:message are not automatically displayed if for example a validation rule is triggered by an inputText:

<h:inputText id="text" value="#{bean.text}" required="true">
     <a4j:ajax execute="blur" />
</h:inputText>
<rich:message for="text" />

This is a quite frequent piece of JSF code. If a user gives focus and then leaves the input, no message is displayed in RichFaces 4.3.2.Final. Instead if I render whatever component, for example

<h:inputText id="text" value="#{bean.text}" required="true">
     <a4j:ajax execute="blur" render="@this" />
</h:inputText>
<rich:message for="text" />

the message is displayed. This is not what I expect from RichFaces.

Do I really need to render something just to trigger the rendering of an ajaxRendered component like rich:message or a4j:outputPanel?

this looks a quite odd, I suppose you didn't want to execute a component named "blur"

<a4j:ajax execute="blur" />

if you are supposed to make use client side validation try the following code:

<h:inputText value="#{userBean.name}" id="name">

     <f:validateRequired />

   <rich:validator />

</h:inputText>

<rich:message for="name" />
