Hi Sammy,

Try this one

valueChangeListener="#{valueChangeManager.valueChanges}"

instead

valueChangeListener="#{valueChangeManager.valueChanges()}"

Regards,

Tamas

Sorry, I just realized that this issue is possibly related to a4j:keepAlive:

...
at org.jboss.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:186)
at org.jboss.seam.jsf.UnifiedELValueBinding.getValue(UnifiedELValueBinding.java:46)
at org.ajax4jsf.taglib.html.facelets.KeepAliveHandler.apply(KeepAliveHandler.java:76)
at com.sun.facelets.tag.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:47)
...

Could You check what happens if You remove this line from the xhtlm code?

<a4j:keepAlive beanName="valueChangeManager.valueChanges()"></a4j:keepAlive>

Or modify it like this:

<a4j:keepAlive beanName="valueChangeManager"/>
