Entities not annotated with @Name problem

[barbacena]

I am receiving a error using the s:convertEntity with entities not annotated with @Name. Do i have to annotate my entities with @Name to have this working?

This is the stacktrace:

19:20:31,802 ERROR [STDERR] 26/09/2008 19:20:31 com.sun.facelets.FaceletViewHandler handleRenderException

In my opinione the @Name isnt a requirement for the EntityConverter to work properly.

From your last entry of your stacktrace pointing at:

org.jboss.seam.Entity$NotEntityException: Unable to establish name of entity class br.gov.tse.secad.modulos.endereco.Municipio_$$_javassist_4
        at org.jboss.seam.Entity.mergeAnnotationAndOrmXml(Entity.java:181)

I would check/do following:

1. is the @Entity set


2. is the equeals(Object o) overwritten


3. make sure u either use XLM-Config or Annotations for ur entities. I dont know the exactly behevior in case of both. Normally, the XML-Config has higher precedence/priority in SEAM. Maybe any (optional?) ORM-XML-Config could cause some confusions what i guess from the merge-Exception of your stacktrace

Greetings

Hi,

It is annotated with @Entity. equals and hashCode overridden with id equality. No XML config is been used and there isn't a "empty" xml.
Any other thoughts for what is happening?
I debug it and it really looks for a @Name config. Using Seam 2.0.2.SP1.

Can you post the backing bean and XHTML code?

In my opinione the @Name is not just not a requirement, is plain wrong to use it in an @Entity

Hi Marcell,

Whats your seam version ? i got same problem using 2.0.2 and 2.0.3 seam versions. It works fine in 2.0.1.GA and i dont know with 2.1.X versions.

[barbacena]

Using 2.0.2.SP1. I'll retrofit to 2.0.1.GA and post results.

[pmuir]

Marcell, please report this in JIRA with an example I can use to reproduce.

[sandeep123.sandeep.mavenir.com]

I faced the same problem with convertEntity,

Setting the fk to fetch = FetchType.EAGER , instead of Lazy fixed it for me.

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "COD_OBJETO_MUNIC_CAPITAL")
private Municipio capital;

Hope this will work for u too.

[barbacena]

I detected the problem but I don't know if it is a bug or not, and if it is a bug it is a JSF or Seam.

Here is the code that do not work:

@Name("municipioPorUfSelectAction")
@Scope(ScopeType.PAGE)
public class MunicipioPorUfSelectAction extends BaseActionBean {

 private Uf uf;

 private Municipio municipio;

 @In
 private MunicipioManager municipioManager;

 @SuppressWarnings("unused")
 @Out(value = "selects_municipiosPorUf", required = false)
 private List<Municipio> municipios;

 @Factory("selects_municipiosPorUf")
 public void listMunicipios() {
  if (uf != null) {
   municipios = municipioManager.recuperaPorUf(uf);
  } else {
   municipios = Collections.emptyList();
  }
 }

 @Observer(value = "selects.uf", create = false)
 public void ufChanged(Uf uf) {
  this.uf = uf;
  listMunicipios();
 }

 public Municipio getMunicipio() {
  return municipio;
 }

 public void setMunicipio(Municipio municipio) {
  log.debug("Setando município: #0", municipio);
  this.municipio = municipio;
  events.raiseEvent("selects.municipio", municipio);
  log.debug("Setado município.");
 }

}

Here is after the fix:

@Name("municipioPorUfSelectAction")
@Scope(ScopeType.PAGE)
public class MunicipioPorUfSelectAction extends BaseActionBean {

 private Uf uf;

 private Municipio municipio;

 @In
 private MunicipioManager municipioManager;

 @Factory("selects_municipiosPorUf")
 public List<Municipio> listMunicipios() {
  if (uf != null) {
   return municipioManager.recuperaPorUf(uf);
  } else {
   return Collections.emptyList();
  }
 }

 @Observer(value = "selects.uf", create = false)
 public void ufChanged(Uf uf) {
  this.uf = uf;
  Contexts.getPageContext().remove("selects_municipiosPorUf");
 }

 public Municipio getMunicipio() {
  return municipio;
 }

 public void setMunicipio(Municipio municipio) {
  log.debug("Setando município: #0", municipio);
  this.municipio = municipio;
  events.raiseEvent("selects.municipio", municipio);
  log.debug("Setado município.");
 }

}

As you see the problem is in a conflict of @Out updating the List.

[pmuir]

Please, still file the bug.
