Using storeId on a Ext.data.Store isn't making unique instances

Question

I have a store APP.store.Posts that I want to instantiate 3 different times. They will all hold the same type of data, but will be using different parameters when reloading, paging, etc. In a controller, I do this in the onLaunch function.

onLaunch: function() {

    Ext.create('APP.store.Posts',{
        storeId: 'unclassifiedPosts'
    });
    Ext.create('APP.store.Posts',{
        storeId: 'positivePosts'
    });
    Ext.create('APP.store.Posts',{
        storeId: 'negativePosts'
    });
},

Then later, in the beforerender listener methods I created on the controller, I do this:

beforeRenderPostsGrid: function(grid) {
    var store = Ext.getStore('unclassifiedPosts');
    store.load();
},
beforeRenderPositivePostsGrid: function(grid) {        
    var store = Ext.getStore('positivePosts');
    store.getProxy().extraParams = {'some_param' : 'some_value'};
    store.load();
    var checkOtherStore = Ext.getStore('unclassifiedPosts'); //THIS STORE NOW HAS SAME PARAMS AS positivePosts STORE
},

The problem is, whichever beforerrender grid is called last, all 3 stores have those parameters. So the initial load is fine, but if I do any refresh, paging, etc. They all show the same data b/c the proxies for each store have identical extraParams somehow.

From what I understood, the storeId parameter was supposed to make my store unique, so am I missing a step?

Answer 1

I ran into this same problem. My store instances were unique, they each got the same proxy for some reason though. The only way I found to solve this was to include the proxy config when I created the store. The full proxy config had to be included though, here was the actual code:

missingStore = Ext.create('ST.store.Attendance', {
    storeId: 'Missing_Attendance',
    proxy: {
        type: 'ajax', 
        url: 'query',
        extraParams: {
            resource: 'Attendance',
            parameters: '6'
        },
        writer: 'pipe'
    }
}),
partialStore = Ext.create('ST.store.Attendance', {
    storeId: 'Partial_Attendance',
    proxy: {
        type: 'ajax', 
        url: 'query',
        extraParams: {
            resource: 'Attendance',
            parameters: '5'
        },
        writer: 'pipe'
    }
}),
attendedStore = Ext.create('ST.store.Attendance', {
    storeId: 'Attended_Attendance',
    proxy: {
        type: 'ajax', 
        url: 'query',
        extraParams: {
            resource: 'Attendance',
            parameters: '4'
        },
        writer: 'pipe'
    }
}),
