Unable to update an entity with non-guid primary key

bugs
1

I was trying to create a flattened datastructure with data from two entities (inner join) to have a cartesian product lines, containing only few fields from both entities. Id columns weren’t present since they weren’t unique. In order to rows had primary key, I added the _mockPk column, which was of type integer. I made all fields of datastructure read-only. I added selection member Selected.

The datastructure was loaded by a workflow load step and then showed in a workflow UI step.

I was expecting I will be able to select rows.

Instead I’ve got an error on UpdateData UIController API call.

How to replicate

  1. Make sure you have at least one record in AllDataTypes where Guid1 column is filled.

  2. checkout the following branch
    GitHub - origam/origam at workflow-ui-step-with-mockpk-selection

  3. open workflow Two tables flattend with mockPk selection test

  4. check any checkbox
