Avoid .map to fill options

[luixal]

Hi,

Not sure if this project is still active... would be good to know :)

I'm having an issue with selectizeOptions, if I define a field this way:

rolesSchema = new SimpleSchema({
  projectId: {
    type: String,
    label: 'project',
    optional: true,
    autoform: {
      // type: "universe-select",
      type: "selectize",
      options: function () {
        return Projects.find().map(function (project, index, cursor) {
          return {
            label: project.name,
            value: project._id
          };
        });
      }
    }
  },

It works like a charm (slow, due to mapping I guess...). If I define it this way (to avoid mapping the entire collection):

projectId: {
    type: String,
    label: function () {
      return I18N.translate('project');
    },
    optional: true,
    autoform: {
      // type: "universe-select",
      type: "selectize",
      options: function () {
        return Projects.find().fetch();
      },
      selectizeOptions: {
        labelField: 'name',
        valueField: '_id'
      }
    }
  },

It doesn't work showing this kind of error on clients console (just one line here, it shows one line per item in the Projects collection):

duplicate id undefined in [...]
{name: "detailedRoles.0.projectId", label: undefined, value: undefined, _id: undefined, selected: false}

It seems it's not taking selectizeOptions in count. Any idea on how to make this work avoiding the .map?

Thanks!

PS: I can't make the mapping in the server and publishing it, I need _id and name values to stay put for showing, editing and other operations.
PS2: yep, I could replicate _id and name in value and label but it seems too much hardcore to me...
