Proxy changes if you set it on the store vs the model

Why is the proxy different when I set it on the model, versus when I set it on the store?

Click on the button "View Proxy" to see the difference.

This should have the SAME URL. In old Ext JS 4, if you set a proxy on the model, the store using that model would inherit the proxy. Not anymore.

I need to set the proxy on the STORE when I want to load a store in a viewmodel with extraparams. (this is an annoyance btw), for example:

Code:

stores: {
                    addresses: {
                        type: 'Address',
                        autoLoad: true,
                        proxy:{
                            extraParams:{
                                CustomId:1
                            }
                        }
                    },

i cannot do this:

Code:

addressWithModelProxy: {
                        model:'AddresswProxy',// 'AddressWithModelProxy',
                        autoLoad: true,
                        proxy:{
                            extraParams:{
                                CustomId:1
                            }
                        }
                    }

So when I use this store, 1st one, in a row/cell editor, and I listen to the rowedit event, I need to add the proxy (THE SAME ONE), to the model as well. Not very DRY. The below code will fail without the extra added proxy on the model.

Code:

onRowEdit:function(editor,context){
context.record.save()
}

This could all be fixed by allowing one to load a model with custom parameters, like you can for a store.

Regardless if this is a "bug" or not, I would like a solution to not have to repeat the proxy and get the intended result, without any code duplication.

Thanks.
