Ok, but I don't understand... ^^
Here is my Action:
public class CatalogueAction extends ActionSupport {
private Catalogue catalogue;
(...)
@RequiredStringValidator(message = "Titre obligatoire", fieldName =
"catalogue.titre")
public String save() {
if (logger.isInfoEnabled()) {
logger.info("[WEB] Sauvegarde du catalogue");
}
this.catalogueService.saveOrUpdateCatalogue(catalogue);
this.addActionMessage(this.messageResources.getMessage("catalogue.save.success",
getLocale()));
return Action.SUCCESS;
}
}
In my edit.jsp, I have this form:
<s:form action="save" validate="true">
<s:hidden name="catalogue.id" value="catalogue.id" />
<tr>
<td><s:textfield id="titre" label="Titre"
name="catalogue.titre" /></td>
</tr>
<tr>
<td><s:textfield id="description" label="description"
name="catalogue.description"/></td>
</tr>
...
When the user submits this form, I get the catalogue in my Action but just
with the new values, and the others are set to null.
So, when I have to re-attach the object ? before the save action ?
