Hello,
We have come across an issue that occurs in the combination of
myfaces-extval and primefaces.
We use the following configuration:
myfaces-extcdi-bundle-jsf20 (1.0.6)
myfaces-extval-core (2.0.6)
myfaces-extval-bean-validation (2.0.6)
myfaces-extval-property-validation (2.0.6)
primefaces-3.5 (revision 8433)
The new primefaces uses a JSF System-Event-Listener to register a widget
builder in the context.
<system-event-listener>
<source-class>javax.faces.component.UIViewRoot</source-class>
<system-event-class>javax.faces.event.PreRenderViewEvent</system-event-class>
<system-event-listener-class>org.primefaces.webapp.PreRenderViewListener</system-event-listener-class>
</system-event-listener>
with the following content:
public class PreRenderViewListener implements SystemEventListener {
public boolean isListenerForSource(Object source) {
return true;
}
public void processEvent(SystemEvent event) throws
AbortProcessingException {
FacesContext.getCurrentInstance().getAttributes().put(Constants.WIDGET_BUILDER_ATTR,
new WidgetBuilder());
}
}
However, this system event listener seems to be called too late, as the
ExtValLazyRendererProxy tries to encode components first. This leads to an
exception at application start:
java.lang.NullPointerException

Primefaces rejected this an an error in their code. Is there a way that
within myfaces-extval-core, it can be made sure that system event
listeners are called before the lazy renderer starts its work?
Thank you very much for your help,
Best regards,
Heiko
