Guys, I just moved to jboss 4.2.0 GA w/ seam cvs. Could you please help me get out on it ? After solve some javascript problems adding on f:view the contentType="text/html" I am facing a new problem: (it was working on 4.0.2 and seam 1.2.0GA) The "component has no value attribute: .." message rises in a selectOneMenu like this: <h:outputLabel for="workspace"> #{messages['labels.taskEdit.workspace']} * </h:outputLabel> <s:decorate id="workspaceDecoration"> <h:selectOneMenu value="#{taskHome.instance.workspace}" id="workspace" converter="workspaceConverter" immediate="true" onchange="this.form.submit();" disabled="#{taskHome.managed}" valueChangeListener="#{taskHome.workspaceChanged}"> <f:selectItem itemValue="" itemLabel="" id="workspacenullitem" /> <f:selectItems value="#{workspaceList.allFromLoggedActor}" /> </h:selectOneMenu> </s:decorate> my workspaceConverter: public class WorkspaceConverter implements Converter { /** Creates a new instance */ public WorkspaceConverter() { } public Object getAsObject(FacesContext facesContext, UIComponent uIComponent, String string) throws ConverterException { if (string == null || string.equals("")) { return null; } Workspace vo = ((EntityManager) Component.getInstance("entityManager")).find(Workspace.class, Integer.valueOf(string)); return vo; } public String getAsString(FacesContext facesContext, UIComponent uIComponent, Object object) throws ConverterException { if (object == null || object.equals("")) { return (String) object; } return String.valueOf(((Workspace) object).getId()); } what I am doing wrong? 1) this same error happens in other parts in my system (I have used this selectonemenus + this same king of converter everywhere 2) I am getting no errors on jboss start.
