Hi Chudak,
well the locationCrudImpl is like so:
PHP Code:
package is.webui;
import is.model.DataStatus;
import is.model.Location;
import java.util.Calendar;
import java.util.List;
import javax.faces.model.SelectItem;
public class LocationCrudImpl extends EntityCrudImpl<Location, Long> {
SelectItem[] locations;
public LocationCrudImpl(Class<Location> entityClass) {
super(entityClass);
}
@Override
public String create() {
entityItem.setEntryDate(Calendar.getInstance());
entityItem.setStatus(DataStatus.P);
return super.create();
}
public List<Location> getChildLocations(Location location) {
List<Location> childLocationList = dao.findListByProperty("parentLocation", location);
return childLocationList;
}
public SelectItem[] getLocations() {
return getSelectItemsByProperty("parentLocation", entityItem.getParentLocation());
}
public SelectItem[] getParentLocation() {
return locations;
}
public void setLocations(SelectItem[] location) {
this.locations = location;
}
}
EntityCrudImpl, which locationCrudimpl implements is like so:
PHP Code:
@Transactional
public class EntityCrudImpl<T, PK extends Serializable> implements
EntityCrud<T, PK> {
static Log log = LogFactory.getLog(EntityCrudImpl.class);
// This is currently being used to create a new
// instance of the entity type
Class<T> entityClass;
String outcomePrefix;
// The current entity (or "backing bean") being worked on
// wired from the applicationContext.xml file
T entityItem;
PagingState pager;
Dao<T, PK> dao;
List<T> pagedItems;
// used to convert an entity from a string to object, or
// object to a string

And the bean declaration is like so:
PHP Code:
...
<bean id="locationVO" class="is.vo.LocationVO">
<property name="locationCrudImpl" ref="locationCrud" />
</bean>
...
Thanks, hope this helps
BeanCreationException: Error creating bean with name 'locationVO'
