Exception thrown when mapping .ToTarget() using context

[SlowLogicBoy]

Code that reproduces the problem:

var mapper = Mapper.CreateNew();
mapper.WhenMapping
    .From<FromModel>()
    .To<ToModel>()
    .Map((s, t) => s.Statistics) //Works Fine
    //.Map(ctx => ctx.Source.Statistics) //Exception thrown
    .ToTarget();

I changed my code to use .Map((s, t) => s.Statistics) instead of .Map(ctx => ctx.Source.Statistics) Just letting you know that this exist ;)

Exception:

System.InvalidOperationException: variable 'vToYvData' of type 'AgileObjects.AgileMapper.ObjectPopulation.IObjectMappingData`2[FromModel,ToModel]' referenced from scope '', but it is not defined

Thanks! I'll sort this out this week.

[SteveWilkes]

Fixed in the latest code, release to follow :)

[SteveWilkes]

Fixed in v0.25 (and now named ToTarget()). Thanks again for the feedback!
