Add new potition attribute

Hi Anton,
I try to add new attribute "stopingTime" to the position record as you did in "EngineHours".
as the flowing code:

//in the position class I added:
public static final String KEY_STOPING_TIME = "stopingTime";

//I added new handler:
package org.traccar.handler;

import io.netty.channel.ChannelHandler;
import org.traccar.BaseDataHandler;
import org.traccar.database.IdentityManager;
import org.traccar.model.Position;

@ChannelHandler.Sharable
public class StopingTimeHandler extends BaseDataHandler {

   private final IdentityManager identityManager;

   public StopingTimeHandler(IdentityManager identityManager) {
       this.identityManager = identityManager;
   }

   @Override
   protected Position handlePosition(Position position) {
       if (!position.getAttributes().containsKey(Position.KEY_STOPING_TIME)) {
           Position last = identityManager.getLastPosition(position.getDeviceId());
           if (last != null) {
               long stopingTime = last.getLong(Position.KEY_STOPING_TIME);
               if (last.getBoolean(Position.KEY_IGNITION) && position.getBoolean(Position.KEY_IGNITION)) {
                   if(!last.getBoolean(Position.KEY_MOTION) && !position.getBoolean(Position.KEY_MOTION))
                       stopingTime += position.getFixTime().getTime() - last.getFixTime().getTime();
               }
               else
                   stopingTime = 0;
               
               position.set(Position.KEY_STOPING_TIME, stopingTime);
           }
       }
       return position;
   }

}

in debug mode it come into the handler and set the attribute value but doesn't find in the database!!!
I didn't find the problem, can you help please?

did you get an solution?

Yes, I got it.

The problem was at the order of handlers
The wrong old order is:

        addHandlers(
                pipeline,
                FilterHandler.class,
                GeocoderHandler.class,
                SpeedLimitHandler.class,
                MotionHandler.class,
                CopyAttributesHandler.class,
                EngineHoursHandler.class,
                ComputedAttributesHandler.class,
                WebDataHandler.class,
                DefaultDataHandler.class,
                StopingTimeHandler.class,
                IdleHandler.class);

correct order is:

        addHandlers(
                pipeline,
                FilterHandler.class,
                GeocoderHandler.class,
                SpeedLimitHandler.class,
                MotionHandler.class,
                CopyAttributesHandler.class,
                EngineHoursHandler.class,
                StopingTimeHandler.class,
                IdleHandler.class,
                ComputedAttributesHandler.class,
                WebDataHandler.class,
                DefaultDataHandler.class);
