Pessoal, estou utilizando CDI, Seam3 e Primefaces. Na construção de uma tela onde existe um combobox e qual mudar o seu valor uma requisição ajax é realizada para atualizar outro combo. Porem, a primeira vez que o combo é alterado tudo funciona, na segunda vez, corre esse erro abaixo. Alguem tem alguma luz?
SEVERE: javax.faces.FacesException: Unexpected error restoring state for component with id fProd_Produto_somProduto. Cause: java.lang.ClassCastException: org.primefaces.component.behavior.ajax.AjaxBehavior cannot be cast to java.util.List.

Descobri que o problema ocorre quando tenho um componente dentro de uma composite component com ajax. Se for fora funciona.

Did you find a solution? I have the same problem. I use
selectManyCheckbox, that are submitted via Ajax.

If you-re using seam and a conversation, you neet to serialize the ajax requests to the backing bean.
I think that maybe you will need the same thing with CDI.
Maybe this URL could help you:

Voltei a atualizar o sistemas e o erro esta ocorrendo agora com um datatable que não fica dentro de um componente, mas agora não sei mais qual pode ser a solução.
