Problem loading Raids and Ts

[prani95]

I have a problem when i try to load the instances like TS and Raids. This is the error:

Here the code where the load crashes:

Here the Database (is just test):

There is a NullReferenceException
Set breakpoints and try to find out which value is null.
If you did, add an if condition like

if (myVariable == null)
{
    continue; // or rather "return;"
}

The problem is here:

public IEnumerable<ScriptedInstanceDTO> LoadByMap(short mapId)
        {
            using (var context = DataAccessHelper.CreateContext())
            {
                foreach (ScriptedInstance timespaceObject in context.ScriptedInstance.Where(c => c.MapId.Equals(mapId)))
                {
                    if (_mapper.Map<ScriptedInstanceDTO>(timespaceObject) != null)
                    {
                        yield return _mapper.Map<ScriptedInstanceDTO>(timespaceObject);
                    }
                }
            }
        }

But i can t find a solution :/

Since I have neither the source nor the time to do that for you,

set a breakpoint at the marked line and step over to find out whose value is null.

_mapper is null:

Thanks for all your help, i will find a way to solve this (hope that) or i will wait someone who can help me

Okay that's what I thought.
Then use the following code

public IEnumerable<ScriptedInstanceDTO> LoadByMap(short mapId)
{
    using (var context = DataAccessHelper.CreateContext())
    {
        foreach (ScriptedInstance timespaceObject in context.ScriptedInstance.Where(c => c.MapId.Equals(mapId)))
        {
            // Insert following if clause
            if (_mapper == null)
            {
                continue;
            }
            // until here
            if (_mapper.Map<ScriptedInstanceDTO>(timespaceObject) != null)
            {
                yield return _mapper.Map<ScriptedInstanceDTO>(timespaceObject);
            }
         }
    }
}

And from now on you shouldn't get this error at this point anymore.

For any reason _mapper doesn't get intialized, maybe later I have time to have a look at the source.
Which files do you have? And did you change something?

[prani95]

Thanks, i m using nosmagic files and adding a lot of things from the latest update in opennos.

Then you did something wrong.

You should search for a null initialization (_mapper = <return value which is null>) or have to search if it gets initialized at all.

Sorry i had forget to put here the mapper. Thanks for all of your time.
