Enum in Seam

[rbcdexia]

I have this factory to show the enum values in my seam application:

@Factory("tiposPoder")
 public TipoPoder[] getTipoPoder() {
 return TipoPoder.values();
 }

This is the code of my enum:

public enum TipoPoder implements Serializable {

 MANCOMUNADO("M")
 , SOLIDARIO("S");
 private String value;
 private TipoPoder(String value){
 this.value = value;
 }
 public String getValue(){
 return value;
 }
 public static TipoPoder fromValue(String s){
 for (TipoPoder obj : TipoPoder.values())
 {
 if (obj.getValue().equals(s))
 return obj;
 }
 return null;
 }
}

Then in my xhtml page I refer to this using the following code:

<s:decorate template="layout/display.xhtml">
 <ui:define name="label">Tipo</ui:define>
 <h:selectOneMenu value="#{apoderadoList.apoderado.tipo}">
 <s:selectItems value="#{tiposPoder}" var="tiposPoder" label="#{tiposPoder.value}" />
 <s:convertEnum/>
 </h:selectOneMenu>
 </s:decorate>

I recived the following exception in my application:

javax.faces.el.EvaluationException: /ApoderadoList.xhtml @75,62 rendered="#{empty apoderadoList.resultList}": Exception getting value of property resultList of base of type : action.SeamApplication1.model.ApoderadoList_$$_javassist_144


Caused by: java.lang.IllegalArgumentException: Unknown name value for enum class action.SeamApplication1.action.enums.TipoPoder: S

Can you help me?

Looks like you've got bad data in your database - hibernate is trying to convert get the enum TipoPoder.S which doesn't exist in your code.

[rbcdexia]

In my database I have 'S' and 'M' data. What I want to display is MANCOMUNDO for 'M' and SOLIDARIO for 'S' in a h:selectOneMenu.
Is there another way to do this?
It still doesn't work.
Thanks for all.

[pmuir]

public enum TipoPoder {

 M("MANCOMUNADO"), S("SOLIDARIO");

 private String label;
 TipoPoder(String label){
 this.label = label;
 }
 public String getLabel(){
 return label;
 }
}

@Enumerated(STRING) TipoPoder tipoPoder;

Pete,

Thanks for the example. What if a number is stored in the database instead of a string? When I try to do this:

public enum TypePayment
{
1("ANNUAL"),
2("SEMIANNUAL");

I get a compile error. Is there a way I could still use and enumeration when the data stored in the database is numeric?

[pmuir]

Sorry, no idea. Try asking on the hibernate forums

[smartbinary]

Hi - just in-case you didn't find a solution to this...and are willing to just use the ordinals from the enum...you should be able to use:

 public enum Status implements Serializable {
 ACTIVE,
 CANCELLED,
 SIGNED;
 }

Then:

 @Column(name = "doc_status_cd")
 @Enumerated(EnumType.ORDINAL)
 public Status getStatus() {
 return status;
 }

Just make sure that your db field (doc_status_cd) in the above example is a numeric type of some sort.

Todd
