I solved the problem, i hope that it gonna help other users who has the same problem. By using the service of ConversionServiceFactoryBean. First, i used the ' form:select ' and 'form:input' , there is my new jsp code :
<td><form:input path="email" type="text"/></td>
<td>
<form:select path="refUniteOrganisParent.id" items="${listeuos}" itemValue="id" itemLabel="nom"/>
</td>
As you can see i retried the id value of the selected item.
Secondly i used this converter:
public class UorgConverter implements Converter<Long, UorgVO>{
@Autowired
private UorgService uo;
@Override
public UorgVO convert(Long id) {
// actions dealing with the service, to retrieve Uorg object from the id sended by the jsp page
return uorgItem;
}
}
After that i configure my xml file by doing this:
<mvc:annotation-driven conversion-service="conversionService"/>
<bean id="conversionService" class="my.package.ConversionServiceFactoryBean">
<property name="converters">
<list>
<bean class="converter.package.location.UorgConverter"></bean>
<!--List of my converters -->
</list>
</property>
</bean>
Thank's to everybody who participates in this post to solve the problem.
Mouhie.
