Create class that extends UIOutputPanel and override its isKeepTransient() method:

public class UIOutputPanelWorkaround extends UIOutputPanel { public boolean isKeepTransient() { // or just return false; Boolean value = (Boolean) getStateHelper().eval(Properties.keepTransient, false); return value; } }

and in faces-config:

<component> <component-type>org.richfaces.OutputPanel</component-type> <component-class>com.example.UIOutputPanelWorkaround</component-class> </component>

Description

Facelets exception occurs on postback phase if there's <a4j:outputPanel> on the page. After this exception further work is not possible as it prevents all other actions. On Richfaces 4.2.0 and older exception doesn't occur. Exception text:
