Service Repository for this issue

Description of problem:

Old DataMapper was divided to two(three) separate editors (DataInputSet/DataOutputSet and Assignments editor) now it is just one editor - Assignments (See https://docs.google.com/document/d/1hq_veY_eBLiweKb0TWdjP27RQKuWGaubUHl4TJoMR04/edit).

Each of editor had individual value string in his fields ([VarName=,Var2Name=] for DataInputSet/DataOutputSet field and {[din]sourceVar->targetVar,[dout]souce2var->target2var} for Assignments field).

For now Assignments DataMapper editor have just one correct value for it's field: {[din]sourceVar->targetVar,[dout]souce2var->target2var}, but if you will import some service with predefined variables, add it to your Business Process and activate it you will see another string in Assignments file: [VarName=,Var2Name=] as it was for old DataInputSet/DataOutputSet. But if you open DataMapper and just save it (without any changes) this string disappear (and will be like it have to be for new DataMapper). See attached video. Services repository also attached.
