reference_many: TypeError: Cannot read property 'identifierValue' of undefined

[matheo]

Scope

reference_may field throwing an exception following the documentation example. I'm using ng-admin 1.0.0

Description

I'm setting up an Array Of Foreign Keys on my Services entity, to edit the related Subservices, but the edition form is throwing a weird error. I'm using the following form for my service:

  service.identifier(nga.field('_id'));
  service.editionView()
    .title('Edit a Service')
    .fields([
      nga.field('name'),
      nga.field('description', 'text'),
      nga.field('subservices', 'reference_many')
      .targetEntity(nga.entity('subservices'))
      .targetField(nga.field('name'))
      .singleApiCall(ids => ({'_id': ids })),
    ]);

My MongoDB _ids works ok in the panel in general, but this field type is throwing:

I see that loading the form, the main entity (service) is GETted but also a list of my subservices GET /rest/subservices?limit=30&skip=0 (cache I think?), then there's a query of the related subservices (or multiple queries if singleApiCall is used, but then comes the exception handling the identifiers :(

Steps to Reproduce

I tried to build my App to see if there was a better trace of the error with no joy, I'm thinking that it has something to do with the "_id" that is not being usedd from the configuration.

Any tips are really appreciated!

For the record, the error is triggered at maReferenceManyFields.js line 20

I've added the .remoteComplete(true) option with no joy. The related entries are queried but the error persist. A problem with the dataStore?

In another entity I have a embedded_list not being filled properly either, the select options are loaded tho, but I cannot select any, a binding problem I think.

Nevermind... my mistake was this line:

.targetEntity(nga.entity('subservices'))

which had to be:

.targetEntity(admin.getEntity('subservicios'))
