Ok, it turned out the problem has nothing to do with AJAX submission. The form has a hidden field which I bound it to sendToFriend.entityIdField property. If I remove this property, everything works fine. But I do need this property to pass the id of the entity to sendToFriend bean. Here is the view code related to the hidden field: | <h:form> | ... | <h:inputHidden value="#{listing.id}" binding="#{sendToFriend.entityIdField}"/> | </h:form> | and the entityIdField property in sendToFriend bean: | private UIInput entityIdField; | Isn't that weird? Binding a UIInput field interferes with injection of entityManager. Any help? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058292#...
