Weired! data is getting mixed between models

Steps to reproduce

On client side, Vuex store clone creates objects of other model/ plugin (with the same id) randomly and thus saves other model instead of currently edited object. Have reviewed both the front end (quasar) and backend (feathers) codes and it all looks neat (no model/ service mixup).

While editing say a Tax object, it clones the tax object as say Promo model object with data from both. If saved it saves promo object. Tax.vue

    btnEdit(props) {
      if (!props || !props.row) {
        return;
      }
      this.thisTax = props.row.clone();
      debug("thisTax", this.thisTax);
      this.taxDialog = true;
    },
    btnSave() {
      this.$v.thisTax.$touch();
      if (this.$v.thisTax.$invalid) return;
      this.loading = true;
      this.thisTax
        .save()
        .then(response => {
          this.$q.notify({
            color: "positive",
            message: `Tax saved ${response.id} - ${response.name}`
          });
          this.$v.$reset();
          this.taxDialog = false;
          this.thisTax = {};
          this.loading = false;
        })
        .catch(e => {
          this.loading = false;
          this.$q.notify({
            color: "negative",
            message: `Error ${e}`
          });
        });
    },

Sample plugin in store/index.js. All plugins are delcared like this

class Tax extends BaseModel {
    // required
    constructor(data, options) {
        super(data, options)
    }
    // required
    static modelName = 'Tax'
}

const taxPlugin = makeServicePlugin({
    Model: Tax,
    service: client.service('tax'),
    enableEvents: false, // turn off socket event listeners. It's true by default
    idField: 'id'
})

Expected behavior

clone Tax object and save the edited Tax item

Actual behavior

Instead of creating Tax object it creats another model object randomly say Promo with clubbed object properpties.

Fixed in feathers-vuex@3.0.1

I’ve figured out the cause. copiesById is on the BaseModel, not on the extended Model. This means every Model shares the same copiesById. I just haven’t noticed it because MongoDB’s ObjectID is unique. I’m working on the fix, now.
