I'm trying to do implement a select component on a page.
I have this :
*CreerClient.java:*
*.....*
// value encoders
@Property
private ApplicatifDtoEncoder applicatifDtoEncoder;
@Property
private TypeClientDtoEncoder typeClientDtoEncoder;
// select models for client types and applications
@Property
private SelectModel selectType;
@Property
private SelectModel selectApplications;
@Inject
SelectModelFactory selectModelFactory;
// data transfer pojos for data retrieving client types and applications
@Property
private List<TypeClientDto> typeClientList;
@Property
private List<ApplicatifDto> applicatifList;
// selected objects for each select and their ids for select value
@Property
private ApplicatifDto selectedApplication;
@Property
private TypeClientDto selectedClientType;
.....
// prepare rendering of the page
void setupRender() {
// retrieve client types and applications id
applicatifList = serviceApplicatif.findAllApplicatifDto();
typeClientList = serviceTypeClient.findAllTypeClientDto();
// initialize selectmodels
selectType = selectModelFactory.create(typeClientList, "nomType");
selectApplications = selectModelFactory.create(applicatifList, "nom");
}
*CreerClient.tml :*
....
<t:Label t:for="typeClientList" />
:
<t:Select value="selectedClientType" t:id="typeClientList"
model="selectType" encoder="typeClientDtoEncoder" />
.....
<t:Select value="selectedApplication" t:id="selectApplications"
model="selectApplications" encoder="applicatifDtoEncoder"
t:zone="applicationsZone" />
.......
*ApplicatifDtoEncoder:*
public class ApplicatifDtoEncoder implements ValueEncoder<ApplicatifDto>,
ValueEncoderFactory<ApplicatifDto> {
@Inject
private IServiceApplicatif serviceApplicatif;
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toClient(java.lang.Object)
*/
@Override
public String toClient(ApplicatifDto value) {
// return the given object's ID
return String.valueOf(value.getId());
}
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toValue(java.lang.String)
*/
@Override
public ApplicatifDto toValue(String clientValue) {
// find the ApplicatifDto object of the given ID in the database
return serviceApplicatif.findApplicatifDto(Long.parseLong(clientValue));
}
// let this ValueEncoder also serve as a ValueEncoderFactory
/*
* (non-Javadoc)
*
* @see
* org.apache.tapestry5.services.ValueEncoderFactory#create(java.lang.Class)
*/
@Override
public ValueEncoder<ApplicatifDto> create(Class<ApplicatifDto> type) {
return this;
}
*TypeClientDtoEncoder :*
public class TypeClientDtoEncoder implements ValueEncoder<TypeClientDto>,
ValueEncoderFactory<TypeClientDto> {
@Inject
private IServiceTypeClient serviceTypeClient;
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toClient(java.lang.Object)
*/
@Override
public String toClient(TypeClientDto value) {
// return the given object's ID
return String.valueOf(value.getId());
}
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toValue(java.lang.String)
*/
@Override
public TypeClientDto toValue(String clientValue) {
// find the typeclientdto object of the given ID in the database
return serviceTypeClient.findTypeClientDto(Long.parseLong(clientValue));
}
// let this ValueEncoder also serve as a ValueEncoderFactory
/*
* (non-Javadoc)
*
* @see
* org.apache.tapestry5.services.ValueEncoderFactory#create(java.lang.Class)
*/
@Override
public ValueEncoder<TypeClientDto> create(Class<TypeClientDto> type) {
return this;
}
}
But when I try to run this page I get :
Render queue error in BeforeRenderTemplate[CreerClient:typeclientlist]:
org.apache.tapestry5.ioc.internal.util.TapestryException
In the console :

[INFO] AppModule.TimingFilter Request time: 205 ms
I am certainly doing something wrong in the definition of mly select, but I
don't see what.
