We've got the same problem with our seam 1.1 project running on JBoss 4.0.5 (current jems 1.2 installer).
We get the following error:
javax.faces.el.EvaluationException: /view/manage/user_search.xhtml @118,174 value="#{messages[selectedObject.title]} #{selectObject.academicTitle}": Cannot get value for expression '#{org.jboss.seam.core.messages}'
