Hi,

I could be able to figure out why there was an issue as mentioned above.

In my document types I was setting the Twitter authorize on a Document type composition , instead of setting it directly on the Home Page.

As it was part of Document type Composition, it could not get the property type and its values .

The reason for this was :

In PreValueHelpers.cs : Skybrud.Social is trying to get the Property type as follows:

publicstaticIDictionary<string, string> GetPreValues(string contentTypeAlias, string propertyAlias) { IContentType contentType = ContentTypeService.GetContentType(contentTypeAlias); PropertyType property = contentType == null ? null : contentType.PropertyTypes.FirstOrDefault(x => x.Alias == propertyAlias);
 return property == null ? newDictionary<string, string>() : GetPreValues(property.DataTypeDefinitionId);
}

By modifying above method  as follows fixes the issue.

publicstaticIDictionary<string, string> GetPreValues(string contentTypeAlias, string propertyAlias) { IContentType contentType = ContentTypeService.GetContentType(contentTypeAlias); PropertyType property = contentType == null ? null : contentType.PropertyTypes.FirstOrDefault(x => x.Alias == propertyAlias); if (property == null)
 {
 property = contentType.CompositionPropertyTypes.FirstOrDefault(x => x.Alias == propertyAlias);
 }
return property == null ? newDictionary<string, string>() : GetPreValues(property.DataTypeDefinitionId);
}

Before Skybrud.Social was getting property type which was available only on Content type page directly.

Now, I have modified such that if the property type is returning null or empty then it gets the property type available on Document type Composition.

Cheers,

Nikita
