Hi,
I am new to Vaadin and I’m using it with Spring Roo.
I created a Form object built with this FormFieldFactory (just paste the code that does not work) :
else if (propertyId.equals("country")) {
ComboBox countryField = new ComboBox();
countryField.setCaption("Pays");
countryField.setImmediate(false);
// Configure container
JPAContainer<Country> containerForCountries = new JPAContainer<Country>(Country.class);
containerForCountries.setEntityProvider(EntityProviderUtil.get().getEntityProvider(Country.class));
countryField.setContainerDataSource(containerForCountries);
countryField.setItemCaptionPropertyId("name");
// Configure converter
Container container = countryField.getContainerDataSource();
PropertyConverter<Country, Long> converter = new BeanFieldPropertyConverter<Country, Long>(Country.class, container, "id");
converter.setPropertyDataSource(item.getItemProperty("country"));
countryField.setPropertyDataSource(converter);
// Configure validator
this.configureValidators(propertyId, countryField, converter);
return countryField;
}
More information : an AccidentBean is bind to the form. This AccidentBean has a ManyToOne relationship with the CountryBean.
The problem is that when I select a Country from the combobox and validate my form, I have the following error :
java.lang.IllegalArgumentException: You have provided an instance of an incorrect PK class for this find operation. Class expected : class java.lang.Long, Class received : class com.declasin.entity.Country.
Is it a problem with my converter ?
Thanks in advance for the help
