It happens when i want to display a datable. And it seems it was caused by the using of an hashmap, if i try by a list it works. But my displaying is to complex to use it. Of course all my custom objects are serialisable . I use this méthod to diplay rows

<h:outputText id="lib_pn" value="#{bean.map[element].myvalue}"/>

bean = my managedBean

map = my hashMap contenig the list of elements

element = the current line given by rich:datatable

myValue = An anttibut of a custom object stored in the map

I'm using richfaces 3.3.3 and an old version pf Jboss 4.2.2GA

Thank you very much for your help

After digging i implemented au listener on the session and i founf that

ERROR [AttributeSerializationDebugger] 2299998 Attribute => {org.ajax4jsf.application.AjaxStateHolder, class org.ajax4jsf.application.AjaxStateHolder} is not serializable.

it seems the problem was caused by  AjaxStateHolder, i'm continuing searching.

In fact this is a problem with jstl c:forEach and Map which are incompatible. As a4j:repeat .

I finally create a custom EL which convert a Map into List and everything works fine
