Brian Leathem resolved SEAMFACES-82.
------------------------------------
Resolution: Done
Fixed in WELD-846
> Injection in faces Converters broken
> ------------------------------------
>
> Key: SEAMFACES-82
> URL: https://issues.jboss.org/browse/SEAMFACES-82
> Project: Seam Faces
> Issue Type: Bug
> Components: CDI Integration
> Affects Versions: 3.0.0.Beta2
> Environment: jboss AS 6 final, windows, war deployment
> Reporter: yangju
> Assignee: Brian Leathem
> Priority: Critical
>
> I have a big war with seam 3 faces, persistence, internationalization, xml
> config, solder modules in the web-inf/lib.
> I have tried to inject managed beans into the jsf converter, but it does not
> matter it is my own bean or seam's bean or weld's bean, the bean is always
> null. It seems that the injection fails silently. The converter code is as
> follows:
> package com.pearson.epen.managedBean.converter;
> import java.io.Serializable;
> import java.util.List;
> import javax.annotation.PostConstruct;
> import javax.enterprise.context.SessionScoped;
> import javax.faces.component.UIComponent;
> import javax.faces.context.FacesContext;
> import javax.faces.convert.Converter;
> import javax.faces.convert.FacesConverter;
> import javax.inject.Inject;
> import javax.persistence.EntityManager;
> import org.slf4j.Logger;
> import com.pearson.epen.account.model.api.TestAdmin;
> import com.pearson.epen.cdi.qualifier.CentralRepo;
> import com.pearson.epen.cdi.qualifier.StaticData;
> @SessionScoped
> @FacesConverter("convert.TestAdmin")
> public class TestAdminConverter implements Converter, Serializable {
> private static final long serialVersionUID = 1L;
> @Inject
> @StaticData
> private List<TestAdmin> admins;
> @Inject
> private FacesContext context;
> @Inject
> @CentralRepo
> private EntityManager em;
> @Inject
> private Logger log;
> @PostConstruct
> public void init() {
> log.info("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%init");
> }
> @Override
> public Object getAsObject(FacesContext context, UIComponent component,
> String value) {
> try {
> Long id = Long.valueOf(value);
> for (TestAdmin admin : admins) {
> if (admin.getId().longValue() == id.longValue()) {
> return admin;
> }
> }
> } catch (Throwable t) {
> log.error("got exception", t);
> }
> return null;
> }
> @Override
> public String getAsString(FacesContext context, UIComponent component,
> Object value) {
> TestAdmin testAdmin = (TestAdmin) value;
> return Long.toString(testAdmin.getId());
> }
> }
> In above code, all injections are null and the @PostConstruct method is never
> called. However, getAsObject(FacesContext context, UIComponent component,
> String value) and getAsString(FacesContext context, UIComponent component,
> Object value) did get called.
> According to some other users, the injection works for them. But I am not
> sure they have multiple seam modules being used in the same war.
> Our war is big and it is difficult to isolate our application to just use
> seam faces, not others. So I am not creating a sample war. But it should be
> easy for seam faces developer to test this.
> I ended up doing bean lookup in my converter and it seems working and the
> bean is found in my converter.
> public List<T> findBeanRef(FacesContext context, String beanELName) {
> BeanManager bm = (BeanManager) (((ServletContext)
> context.getExternalContext().getContext())
>
> .getAttribute("org.jboss.seam.faces.javax.enterprise.spi.BeanManager"));
> Bean bean = bm.getBeans(beanELName).iterator().next();
> CreationalContext ctx = bm.createCreationalContext(bean);
> List<T> list = (List<T>) bm.getReference(bean, bean.getClass(), ctx);
> return list;
> }
