Key: RF-8616
URL: https://jira.jboss.org/jira/browse/RF-8616
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Environment: JBoss 6 M2, Tomcat 6.0.24, RichFaces 4.0.0-SNAPSHOT
Reporter: Pavol Pitonak
The following code doesn't work. However, it works fine with f:ajax or if
prependId="false" is removed.
<h:form prependId="false">
<h:outputLabel value="Name:" for="nameInput" />
<h:inputText id="nameInput" value="#{richBean.name}">
<a4j:ajax event="keyup" render="output" />
</h:inputText>
<h:panelGroup id="output">
<h:outputText value="Hello #{richBean.name}!" rendered="#{not empty
richBean.name}" />
</h:panelGroup>
</h:form>
