Why form is not 'dirty' after adding/removing object in array?

[olegkalyta]

I need to save added objects in array & be able to save state, if objects were deleted from array.
In other words, i try to accomplish this behavior:

1. I have initialised array with 1 object inside
2. After adding, removing any objects in this array, i expect to have dirty form, but it is not.

Please check gist with this example:

Shallow equality cannot detect when you change an element inside an array. You need to return a new array without the element you want to remove rather than mutating the existing array.

You mean, explicitly mutate state in my own handle array methods and do not use

formReducer.plugin 'redux-form/ADD_ARRAY_VALUE' ?

[olegkalyta]

In my gist, i use standard methods for adding/removing array elements and i thought, they should return new arrays to change form status to dirty.
Anyway, as @clayne11 adviced, i manually return new arrays in plugin, but it still does not work for me.

@erikras is there some sort of best practise for such task?

This is unfortunately a known bug (#391, #484) that is being taken into consideration for the next version, but for now, I'm afraid you're going to have to do array length checks yourself.

+1 for this being implemented. WRT to form dirtiness, if I touch a field, the form is dirty, so why not apply the same at the form level? If I touch the form by adding or removing fields, the form itself should be dirty.

Please continue the discussion in #391.
