actions.reset sets model value to undefined

[jameshy]

When I have a model like this:

{
    user: {
        anArray: []
    }
}

Calling actions.reset('user') multiple times results in anArray to become undefined.

Here is a gist that shows the problem (1.3.2):

The same gist without the problem (1.0.6)

Clicking 'Reset Form' multiple times will cause the model array to become undefined.

Does this also occur for you in 1.4.0 by any chance?

@davidkpiano this is 90% for sure the same issue I'm having.

I have store.payment which contains a meta.lineItems. lineItems is an array and is the only model affected by this bug. The rest of payment and payment.meta is reset correctly.

However, for each key of payment.meta.lineItems[0] a rrf/change is dispatched with no value thus clearing that key completely from the array.

      dispatch(actions.reset('payment')),

Which results in these actions being dispatched somehow:

However, if I switch my reset out for a change to the initialPayment object (the same object used in creating the form reducer, my problem is solved.

      dispatch(actions.change('payment', initialPayment)),

(@jameshy you can use that as a workaround for now also... instead of a reset, just change it to the initial on your own.)

Problem occurs in versions:

• 1.3.2
• 1.4.0
• 1.4.1

I don't have time to test each version but:

v1.0.15 works just fine!

@davidkpiano I am using version 1.14.1 and I am having the same issue @lasergoat had: I have store.sites[] and when dispatch(actions.reset(sites[0])) the key is updated in the model with undefined value.

[davidkpiano]

@agustingp That should be expected behavior - consider a non-empty array with more than one element. Choosing to reset a single value should result in, e.g., [undefined, 1, 2, 3, 4].

@davidkpiano thank you for answering! So, how can I do to reset (setting its initial value) the model of an object stored inside the array?

[davidkpiano]

If the array has dynamically loaded values, with actions.load('model.array[0]', 'something'), it should naturally reset to that 'something' as the initial value. If it doesn't, please open a separate ticket and I'll look at it.
