rerender and required=true?

[nimo22]

I have that:

<rich:panel>
 <h:inputText id="login" value="#{myBean.login}" required="true"/>
</rich:panel>

<rich:panel>
 <h:inputText id="name" value="#{myBean.name}">
 <a4j:support event="onblur" reRender="output" />
 </h:inputText>
</rich:panel>

<rich:panel>
 <h:outputText id="output" value="#{myBean.name}" />
</rich:panel>

When I enter a value in the inputText (id="name"), then it should immediately rerender the outputText (id="output"). But it does NOT!

You can see, in h:inputText (id="login"), I have set required="true".
When I set required="false", then the rerendering works !!!

But I need to set the required="true" and I need to rerender other attributes, too.

How can I do that ?

(immediate=true in h:inputText id="name" does not work)
