I am using an AjaxFormLoop component. There is no database involved, so
the code should be simple.
The add operation in onAddRowFromVehicles() works. I can see that
because the list of vehicles has alwas the correct size. But Properties
of Vehicle (like vehicle.model) are never updated, no matter what I type
into the for fields.
Any hints? I have no idea and think that it should work because my list
of vehicles is persisted.
Here is a snippet of my relevant parts:
class Page{
@Property @Persist
private List<Vehicle> vehicles;
@Property
private Vehicle vehicle;
Object onAddRowFromVehicles() {
Vehicle vehicle = new Vehicle();
vehicle.setType(VehicleType.PKW);
this.vehicles.add(vehicle);
return vehicle;
}
public ValueEncoder<Vehicle> getVehicleEncoder(){
return new VehicleValueEncoder();
}
public class VehicleValueEncoder implements ValueEncoder<Vehicle>{
private static final String SEP = "|";
@Override
public String toClient(Vehicle value) {
StringBuffer result = new StringBuffer();
result.append("vehicle");
result.append(SEP);
result.append(value.getType().name());
result.append(SEP);
result.append(value.getModel());
result.append(SEP);
result.append(value.getLicenseNumber());
result.append(SEP);
result.append(value.getLengthCentimeter());
result.append(SEP);
result.append(value.getHeightCentimeter());
result.append(SEP);
return result.toString();
}
@Override
public Vehicle toValue(String clientValue) {
String[] splitted = clientValue.split("\\" + SEP); // use a
regex
Vehicle vehicle = new Vehicle();
vehicle.setType(VehicleType.valueOf(splitted[1]));
vehicle.setModel(splitted[2]);
vehicle.setLicenseNumber(splitted[3]);
vehicle.setLengthCentimeter(Integer.valueOf(splitted[4]));
vehicle.setHeightCentimeter(Integer.valueOf(splitted[5]));
return vehicle;
}
}
}
