[Form] Unexpected interaction between storeMixin and referenceMixin

[rodolpheV]

Unexpected behaviour

I have a main form which need the reference list 'countryList'.
If the 'countryList' reference is reloaded, this form does a this.setState(this._getStateFromStores()).
Problem: If I am editing an item with this main form, and if another view reload the 'countryList' reference, I lose my current modifications in the main form because it reload its state from the store.

Expected behaviour

I would expect the store behaviour to do a getStateFromStore only for the updated nodes of the store, not for all my listening nodes.

Versions

Focus-core: 2.1.1
Focus-components: 2.1.7-1

@rodolpheV Indeed it is problematic. The handlers are not as precised as needed.
To avoid this problem, you can override this by using onChange on your form :
https://github.com/KleeGroup/focus-components/blob/5af5f0e8244fadee88cb733c737a7cd25d855d18/src/common/mixin/store-change-behaviour.js#L60
That way, you can decide to trigger or not the this.setState(this._getStateFromStores(), () => this._afterChange(changeInfos));

If I have time, I will come and see you today.
