New Rotator query - Sitefinity - Front- & Back-End Development

Hi,

I have created a Dynamic Module that I am using to display ads. I have adapted your NewsRotator example to fit my scenerio. Everything seems to work fine until I run the query to join my dynamic content and the image.

Below is the query used for the NewsRotator example:

var dataSource = App.WorkWith().NewsItems().Publihed()

.Get().Take(this.NewsLimit)

.ToList()

.Join(

App.WorkWith().Images().Publihed()

.Get()

.Where(i => i.Parent.Title == "Thumbnails"),

item => item.Title.Value,

image => image.Title.Value,

(item, image) => new NewsItem = item, NewsImage = image

);

And here is my code,

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();

Type businessPremiumListingType = TypeResolutionService.ResolveType(PremiumListingContentType);

var imagesQuery = App.WorkWith().Images().Publihed()

.Get()

.Where(i => i.Parent.Title == "Thumbnails");

var datasource = dynamicModuleManager.GetDataItems(businessPremiumListingType)

.Where(i => i.Status == ContentLifecycleStatus.Live && i.Visible == true)

.Take(this.BusinessLimit);

var ds = datasource.Join(imagesQuery,

item => item.GetValue<Guid>("ad"),

image => image.Id,

(item, image) => new BusinessItem = item, BusinessImage = image );

My Dynamic module has a field called ad the holds the id of the image that I want to display. This query looks fine to me but when it executes, I get the following error:

Incorrect number of parameters supplied for lambda declaration

I do not see what the difference is between my code and the NewsRotator example. Can anyone shed some light on why this is happening and the correct implementation for what I am trying to accomplish?

Thanks,
Bobby
