I'm trying to present a drop-down list for users to select from which is built from a list queried from the database. I will attach the selected entity to another entity. The problem is that I get value="0" for every in the list and I get this exception (full dump at bottom) when submitting the form with a selected value: javax.servlet.ServletException: Provided id of the wrong type. Expected: class java.lang.Long, got class java.lang.String So I put a breakpoint in EntityConverter.getAsString and see that whereas the examples have the value parameter set to an object of an actual class (e.g. Continent in seam-ui), I have a Provider_$$_javassist_21 object. Looking into the object, the handler.target object is the data that I care about. Yet the getIdFromEntity() call returns null as found directly in the javassist subclass. Given that all my code is very similar to the example code I don't know where to look from here. thanks Web page: | <s:decorate id="recentDecor" template="/WEB-INF/template/edit.txml"> | <ui:define name="label">#{messages.referralSpecialistLabelRecent}</ui:define> | <h:selectOneMenu value="#{referralController.recentChoice}"> | <s:convertEntity/> | <s:selectItems value="#{recentSpecialists}" var="spec" label="#{spec.lastName}, #{spec.firstName} #{spec.middleInitial}, #{spec.suffixName}" noSelectionLabel="#{messages.referralSpecialistNoRecent}"/> | <a:support event="onchange" action="#{referralController.pickRecentSpecialist}"/> | </h:selectOneMenu> | </s:decorate> | Controller: | @DataModel | @SuppressWarnings("unused") | private List<Provider> recentSpecialists; | | @Factory("recentSpecialists") | @SuppressWarnings("unchecked") | public void loadRecentSpecialists() | { | recentSpecialists = entityManager.createQuery("select p from Provider p") | .setMaxResults(25) | .getResultList(); | } | Entity Definition (getters/setters removed but completely standard): | | @Entity | public class Provider extends PracticeStaff { | | // private fields ****************************** | | // Should never be null.
