I make mini example seams app (typical user-rol tables). The source code was generated with hibernate-tools beta4 and was fixed some errors of generator.
usuario (usuario,password) --> Id (usuario) rol(rol) --> Id (rol) usuario_rol(usuario, rol) --> Composite id (usuario, rol) Jboss throws this error when I go to "http://localhost:8080/seamapp/editUsuarioRol.jsf"; : 10:29:27,361 ERROR [[/seamapp]] Cannot set value for expression '#{usuariorolEditor.instance.id}' to a new value of type java.lang.String | javax.faces.el.EvaluationException: Cannot set value for expression '#{usuariorolEditor.instance.id}' to a new value of type java.lang.String | at org.apache.myfaces.el.ValueBindingImpl.setValue(ValueBindingImpl.java | :304) | . | . | Caused by: java.lang.IllegalArgumentException: argument type mismatch | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl. | java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAcces | sorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.apache.myfaces.el.PropertyResolverImpl.setProperty(PropertyResolv | erImpl.java:368) | ... 33 more The source code composite id : | // Generated 23-feb-2006 17:09:37 by Hibernate Tools 3.1.0.beta4 | | import javax.persistence.Column; | import javax.persistence.Embeddable; | | | /** | * UsuarioRolId generated by hbm2java | */ | @Embeddable | | public class UsuarioRolId implements java.io.Serializable { | | | // Fields | | private String usuario; | private String rol; | | | // Constructors | | /** default constructor */ | public UsuarioRolId() { | } | | | /** full constructor */ | public UsuarioRolId(String usuario, String rol) { | this.usuario = usuario; | this.rol = rol; | } | | | | // Property accessors | @Column(name="usuario", unique=false, nullable=false, insertable=true, updatable=true, length=20) | | public String getUsuario() { | return this.usuario; | } | | public void setUsuario(String usuario) { | this.usuario = usuario; | } | @Column(name="rol", unique=false, nullable=false, insertable=true, updatable=true, length=20) | | public String getRol() { | return this.rol; | } | | public void setRol(String rol) { | this.rol = rol; | } | | | | | public boolean equals(Object other) { | if ( (this == other ) ) return true; | if ( (other == null ) ) return false; | if ( !(other instanceof UsuarioRolId) ) return false; | UsuarioRolId castOther = ( UsuarioRolId ) other; | | return ( (this.getUsuario()==castOther.getUsuario()) || ( this.getUsuario()!=null && castOther.getUsuario()!=null && this.getUsuario().equals(castOther.getUsuario()) ) ) | && ( (this.getRol()==castOther.getRol()) || ( this.getRol()!=null && castOther.getRol()!=null && this.getRol().equals(castOther.getRol()) ) ); | } | | public int hashCode() { | int result = 17; | | result = 37 * result + ( getUsuario() == null ? 0 : this.getUsuario().hashCode() ); | result = 37 * result + ( getRol() == null ? 0 : this.getRol().hashCode() ); | return result; | } | | } | This error is throwing when i select one rol for one user. I have in "editUsuarioRol.jsf" one inputText box for id. How introduce "id" in this box if "id" is a object not a String ???
