afArrayField reactivity bug because of name property on element removal and add

[horodnicdragos]

I am using afArrayField with two fields using properties from the same collection (Fa). The collection has nested values and on the second field of the form (fi.$.uni), it returns an option list depending on the selected value from the first field (fi.$.fac).

Everything works well, until I remove on of the array's elements by clicking the '-' button. Afterwards the second field will not show the corresponding options. I did find something that I hope to be helpful.

First of all, here is my schema:

Schemas.CV = new SimpleSchema(
  fi: type: [ Object ]
  'fi.$.uni':
    type: String
    autoform: options: ->
      Fa.find().fetch().map (obj) ->
        {
          label: obj.title
          value: obj.title
        }
  'fi.$.fac':
    type: String
    autoform: options: ->
      uni = AutoForm.getFieldValue(@name.replace('.fac', '.uni'))
      console.log @name
      if !uni
        []
      else
        Fa.findOne(title: uni).fac.map (obj) ->
          {
            label: obj
            value: obj
          }
)

Template:

{{> afArrayField name='fi' fields="fi.$.uni, fi.$.fac"}}

After some brief debugging. it appears that @name does not update on array removal. Here is an example: I have the following name values for two elements in the array:

fi.0.fac fi.1.fac

I add another one:

fi.0.fac fi.1.fac fi.2.fac

I remove the middle element and what remains is:

fi.0.fac fi.2.fac

Adding another element will result in:

fi.0.fac fi.2.fac fi.3.fac

I am pretty sure this is the cause of not being able to reactively alter options list after removing an element from the array.

Hi @horodnicdragos I have experienced the same issue when creating my custom templates. I cannot access the AutoForm.getFieldValue correctly because the template.data.name property does not update.

If you find any solution or clue, please, let me know. Thanks
