When removing object from array, left with null instead of complete removal at index

[avishaan]

When I remove something like the below:

it looks like it get's removed, but when I go back to the document I see it as a blank entry

when checking in the database, I see that null is left behind instead of the array element being removed

it really should remove the entire element of the array, not replace it with null

because this package depends on https://github.com/aldeed/meteor-simple-schema#validating-data I realized I could just delete those null values upon save with a simple one-liner as follows in the autoValue function

Layouts.attachSchema(new SimpleSchema({
  'orgID': {
    'type': String,
    'label': 'Unique Id',
    'max': 50,
  },
  'categoryIds': {
    'type': [String],
    'label': 'Category Ids the schema applies to',
  },
  'graphs': {
    type: [ChartSchema],
    'autoValue': function() {
      // remove the null in array on update https://github.com/orionjs/orion/issues/429
      return this.value.filter(value => value !== null);
    },
  },
}));

Although it seems this issue presents itself in the actual dependency, I thought it would be helpful to have a post here as well for future reference
