when i commented both of the h:selectOneMenu component after login click the page redirected to another, and if i uncomment one of them button does not work.

You've probably got errors occuring on the coversion, validation or update model phase. Put an h:messages component on the page to see.

hi petemuir,
u're right i put h:messages into login page and i got an error like this :

 . value could not be converted to the expected type

i wrote my own converter as you told me

@Transactional
 public Converter getApplicationConverter() {
 return new Converter() {

 @Transactional
 public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException {
 if (arg2 == null) {
 return null;
 }
 try {
 return ((EntityManager) Component.getInstance("entityManager")).find(Application.class, Integer.valueOf(arg2));
 } catch (NumberFormatException e) {
 throw new ConverterException("Cannot Find Selected Language", e);
 }
 }

 @Transactional
 public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException {
 if (arg2 instanceof Language) {
 Application application = (Application) arg2;
 return application.getName().toString();
 } else {
 return null;
 }
 }

 };
 }

here is my entity bean :

@Entity
@Table(name = "APPLICATION",schema="BillAdmin")
@Name("application")
@Scope(ScopeType.SESSION)
public class Application implements Serializable {

 @Id
 @Column(name = "APPLICATION_ID", nullable = false)
 private BigDecimal applicationId;

 @Column(name = "NAME")
 private String name;

 @Column(name = "CODE")
 private BigInteger code;

 @Column(name = "DESCRIPTION")
 private String description;

 @Column(name = "REMARK")
 private String remark;

 @Column(name = "REC_STATUS")
 private BigInteger recStatus;

 @Column(name = "USER_ID")
 private BigInteger userId;

 @Column(name = "REG_DATE")
 @Temporal(TemporalType.DATE)
 private Date regDate;

 @Column(name = "UPD_DATE")
 @Temporal(TemporalType.DATE)
 private Date updDate;

 @OneToMany(cascade = CascadeType.ALL, mappedBy = "applicationId")
 private Collection<ApplicationsConfig> applicationsConfigCollection;

 public Application() {
 }

 public Application(BigDecimal applicationId) {
 this.applicationId = applicationId;
 }

 public BigDecimal getApplicationId() {
 return this.applicationId;
 }
 public void setApplicationId(BigDecimal applicationId) {
 this.applicationId = applicationId;
 }

 public String getName() {
 return this.name;
 }

 public void setName(String name) {
 this.name = name;
 }

 public BigInteger getCode() {
 return this.code;
 }
 public void setCode(BigInteger code) {
 this.code = code;
 }

 public String getDescription() {
 return this.description;
 }

 public void setDescription(String description) {
 this.description = description;
 }

 public String getRemark() {
 return this.remark;
 }

 public void setRemark(String remark) {
 this.remark = remark;
 }

 public BigInteger getRecStatus() {
 return this.recStatus;
 }

 public void setRecStatus(BigInteger recStatus) {
 this.recStatus = recStatus;
 }

 public BigInteger getUserId() {
 return this.userId;
 }
 public void setUserId(BigInteger userId) {
 this.userId = userId;
 }
 public Date getRegDate() {
 return this.regDate;
 }
 public void setRegDate(Date regDate) {
 this.regDate = regDate;
 }
 public Date getUpdDate() {
 return this.updDate;
 }
 public void setUpdDate(Date updDate) {
 this.updDate = updDate;
 }
 public Collection<ApplicationsConfig> getApplicationsConfigCollection() {
 return this.applicationsConfigCollection;
 }
 public void setApplicationsConfigCollection(Collection<ApplicationsConfig> applicationsConfigCollection) {
 this.applicationsConfigCollection = applicationsConfigCollection;
 }
 @Override
 public int hashCode() {
 int hash = 0;
 hash += (this.applicationId != null ? this.applicationId.hashCode() : 0);
 return hash;
 }
 @Override
 public boolean equals(Object object) {
 if (!(object instanceof Application)) {
 return false;
 }
 Application other = (Application)object;
 if (this.applicationId != other.applicationId && (this.applicationId == null || !this.applicationId.equals(other.applicationId))) return false;
 return true;
 }

 @Override
 public String toString() {
 return "com.magti.seam.beans.billAdmin.Application[applicationId=" + applicationId + "]";
 }
}

can u tell me why i got this error ?

[grdzeli_kaci]

i tryed to use another ways.

here is fragment of my program :

1. login page:

<h:selectOneMenu styleClass="font_style" value="#{application.name}" converter="#{converters.applicationConverter}">
 <s:selectItems value="#{applications.resultList}" var="application" label="#{application.name}"/>
 </h:selectOneMenu>

2. components.xml

 <framework:entity-query name="applications" ejbql="select a from Application a" />
 <framework:entity-home name="applicationHome" entity-class="com.magti.seam.beans.billAdmin.Application"/>
 <factory name="application" value="#{applicationHome.instance}" />

3. My Converter :

@Transactional
 public Converter getApplicationConverter() {
 return new Converter() {

 @Transactional
 public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException {
 if (arg2 == null) {
 return null;
 }
 try {
 return ((EntityManager) Component.getInstance("entityManager")).find(Application.class, Long.valueOf(arg2));
 } catch (NumberFormatException e) {
 throw new ConverterException("Cannot Find Selected Language", e);
 }
 }

 @Transactional
 public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException {
 if (arg2 instanceof Application) {
 Application application = (Application) arg2;
 return application.getApplicationId().toString();
 } else {
 return null;
 }
 }

 };
 }

4. and entity bean i posted above, but i remove @Name annotation.

but error still appears,

/login.xhtml @37,153 value="#{application.name}": Exception setting property name of base with class com.magti.seam.beans.billAdmin.Application, Bean: com.magti.seam.beans.billAdmin.Application, property: name, argument type mismatch

#{application.name} references a String, you are trying to set it with a Application object. Likewise for language. Read up on JSF converters and what they do. And take a look at the EntityConverter on the wiki as it does what you are trying to do for you...

hi again,
for background i read JSF converters,
then i go to wiki for SeamEntityConverter (http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityConverter)
i download zip file ant tryed to understand.

after all i deside to do my job.

1.i added xmlns:ec="http://jboss.com/products/seam/entityconverter/taglib" into my facelet. and change selectonemenu component tag like this :

<s:decorate>
 <h:selectOneMenu styleClass="font_style" value="#{application.name}">
 <s:selectItems value="#{applications.resultList}" var="name" label="#{application.name}"/>
 <ec:convertEntity entityClass="com.magti.seam.beans.billAdmin.Application"/>
 </h:selectOneMenu>
 </s:decorate>

2. i modifyed my component.xml file :

<framework:entity-query name="applications" ejbql="select a from Application a" />
 <framework:entity-home name="applicationHome" entity-class="com.magti.seam.beans.billAdmin.Application"/>
 <factory name="application" value="#{applicationHome.instance}" />

3. i put entityconverter.jar file into my WEB-INF/lib.

but page did not load :

Value is no String (class=com.magti.seam.beans.billAdmin.Application, value=com.magti.seam.beans.billAdmin.Application[applicationId=4]) and component _id17:_id26with path: {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /login.xhtml][Class: javax.faces.component.html.HtmlForm,Id: _id17][Class: org.jboss.seam.ui.UIDecorate,Id: _id25][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: _id26]} does not have a Converter

is there any mistake i did ?

[grdzeli_kaci]

i can't resolve this problem yet,
anybody knows about it ?

[grdzeli_kaci]

[pmuir]

At the very least it should be this

<h:selectOneMenu styleClass="font_style" value="#{foo.application}">
 <s:selectItems value="#{applications.resultList}" var="name" label="#{application.name}"/>
 <ec:convertEntity />
</h:selectOneMenu>

[pmuir]

Oops, no, this is better

<h:selectOneMenu styleClass="font_style" value="#{foo.application}">
 <s:selectItems value="#{applications.resultList}" var="application" label="#{application.name}"/>
 <ec:convertEntity />
</h:selectOneMenu>

[grdzeli_kaci]

sorry petemuir for my disturb :(

i tryed it for a week and could not resolve this problem,

i added ur jar file into build.xml file

<copy todir="${war.dir}/WEB-INF/lib">
 <fileset dir="${lib.dir}">
 <include name="ajax4jsf.jar" />
 <include name="oscache*.jar" />
 <include name="jsf-facelets.jar" />
 <include name="jboss-seam-*.jar" />
 <include name="entityconverter.jar" />
 <exclude name="jboss-seam-gen.jar" />
 </fileset>
 </copy>

for copping this jar into war file(WEB-INF/lib)

<h:selectOneMenu styleClass="font_style" value="#{foo.application}">

what did u mean in foo?sorry i can't understand :(

[pmuir]

<h:selectOneMenu styleClass="font_style" value="#{foo.application}">

Foo is the backing bean on which you wish to set the application property. It could be just #{application} - though I'm not sure how well this works on the whole.

ok,
1. i had entityconverter.jar into my war file
2.my project component.xml file looks like :

<framework:entity-home name="applicationHome" entity-class="com.magticom.billing.businesslayer.entitybeans.billAdmin.Application" />
 <factory name="application" value="#{applicationHome.instance}" />
 <framework:entity-query name="applications" ejbql="select a from Application a" />

"applicationHome" is baking bean for login page.
"application" is name of this baking bean instance.
"applications" is is entity query.

3. my login page looks like

<h:selectOneMenu styleClass="font_style" value="#{application}">
 <s:selectItems value="#{applications.resultList}" var="application" label="#{application.name}"/>
 <ec:convertEntity />
 </h:selectOneMenu>

in "h:selectOneMenu" component "#{application}" is name of the baking bean,
in "s:selectItems" component "#{applications.resultList}" is the result of entity query
the var attribute point to the factory.
ant at list this is <ec:convertEntity /> is for converting entity.

but always i got the same error

Value is no String (class=com.magti.seam.beans.billAdmin.Application, value=com.magti.seam.beans.bil
lAdmin.Application[applicationId=4]) and component _id17:_id26with path: {Component-Path : [Class: j
avax.faces.component.UIViewRoot,ViewId: /login.xhtml][Class: javax.faces.component.html.HtmlForm,Id:
 _id17][Class: org.jboss.seam.ui.UIDecorate,Id: _id25][Class: javax.faces.component.html.HtmlSelectO
neMenu,Id: _id26]} does not have a Converter

is another way to resolve this problem? without entity converter ?
or what i did wrong ?

oo and i put entityconverter.jar into jboss server lib folder. is it needed ?

[pmuir]

No. Don't put it in the lib folder. Follow the examples provided for packaging.

It looks like converter isn't getting used. As for why... You should check with a breakpoint whether the converter is used. You could also try registering the converter by id - org.jboss.seam.EntityConverter iirc.
