Data Mapping for multilingual strings using Code

Question

I asked a question related to a configuration of mappings via code some time ago. I have an issue with adding of multilingual strings to a target(Sitecore) item.

Initial question: Data Mapping Using Code

I found that I have to add 1 more step (Select Languages) comparing with a default flow. Also, I used "Resolve Multilanguage Sitecore Item Dictionary" pipeline step instead of "Resolve Sitecore Item". I could populate at least shared fields before the changes above, but can't do it now.

Have following error in the log:

ManagedPoolThread #6 17:12:28 ERROR [Data Exchange] Pipeline step processing will abort because no source object could be resolved from the pipeline context. (pipeline: Single Attribute Sync Pipeline, pipeline step: Apply Mapping, pipeline step identifier: acc13c65-140a-484a-bb6c-11d0cb999774, target location: ec64487d-e7e6-40b0-a86c-40c74b95e04e)

As I understand, my custom ValueMappingSet is not valid anymore. Does somebody have any example of mapping multi-language data via code?

Update:

My steps:

Select languages

Resolve Multilanguage Sitecore Item Dictionary

Apply Mapping

Thanks in advance.

If I rightly understand you don't want to use configuration for mapping and you need to implement multi language support for mapping Sitecore items.

I will begin form the end.

There is Update Sitecore Item Pipeline Step - pipeline step that can create or update Sitecore item(s).

This pipeline step can handle 2 target objects. It checks whether types are:

1. ItemModel
2. IDictionary<string,ItemModel> where key is language

Here is how you can use code mapping:

var target = GetTarget(); //returns IDictionary<string,ItemModel>
var source = GeSource();  //returns source object

//Check if item model exist by language before map data

target["en"]["fieldTitle"] = source["en"].Title;
target["en"]["fieldDescription"] = source["en"].Description;

target["uk"]["fieldTitle"] = source["uk"].Title;
target["uk"]["fieldDescription"] = source["uk"].Description;

When target is Dictionary?

Target is dictionary when Select Languages Pipeline Step and Resolve Multilanguage Sitecore Item Dictionary Pipeline Step are used.

• Select Languages Pipeline Step - allows to specify supported languages.
• Resolve Multilanguage Sitecore Item Dictionary Pipeline Step - resolves item by language and creates target dictionary for specified languages if it does not exist.

Update from Maxim:

I had a wrong configuration in pipeline step "Resolve Multilanguage Attribute Item" ("Resolved Object Location" was empty). Vlad helped me to find this missing setting and solve my exception.

To populate the fields I used the following logic (based on Vlad's suggestions):
