Hi All, I am coming from a struts back ground, and I am lost for where to start trying to debug this problem. I have an Object (Delivery) with an association from a pick list (Status) I created a seam-gen project and played around with it, but I don't want to have to navigate to a different web page just to pick the status for my delivery. I want to provide a DDLB on the delivery edit page, and allow the user to select from a list that is in the status DB. Seems simple enough, in Struts I'd simply put this list into a context and reference it. What I did in Seam may not be right. In the components.xml file, I defined a framework query like this: <framework:entity-query name="allStatus" | entity-manager="#{em}" | ejbql="select s from Status s" | order="s.description"/> Then I reference it in my xhtml file as follows: <s:decorate id="statusDecoration" template="layout/edit.xhtml"> | <ui:define name="label">status</ui:define> | <h:selectOneMenu id="status" value="#{deliverableHome.instance.status}"> | <s:convertEntity /> | <s:selectItems value="#{allStatus.resultList}" | var="deliverableHome.instance.status" | label="#{status.description}"/> | </h:selectOneMenu> | </s:decorate> The list of status codes show up in a drop down list, but when I try to save the record, I get an HBM mapping error: java.lang.IllegalArgumentException: Unknown
