Hi,
I have a grid that has three textfield filters (name, city, county), based on which i filter the grid remotely. Everything works fine, except with paging. Since JsonStore is in charge of paging, I found on api docs I can pass any values I want with baseParams property collection.
So I have created three methods for each textfield filter. Each of them get the value, validates and returns it.

Code:
owner.filters = new Object();
owner.filters.store = function () {
    var obj = Ext.get('storeFilter');
    var val = '';
    if (obj != null) {
        val = obj.getValue();
        if (val == owner.grid.foodstoreFilterEmptyText)
            val = '';
    }

    return val;
}

owner.filters.county = function () {
    var obj = Ext.get('countyFilter');
    var val = '';
    if (obj != null) {
        val = obj.getValue();
        if (val == owner.grid.countyFilterEmptyText)
            val = '';
    }

    return val;
}

owner.filters.city = function () {
    var obj = Ext.get('cityFilter');
    var val = '';
    if (obj != null) {
        val = obj.getValue();
        if (val == owner.grid.cityFilterEmptyText)
            val = '';
    }

    return val;
}
And here is how I set baseParams for the store
Code:
baseParams: { storeName: owner.filters.store(), city: owner.filters.city(), county: owner.filters.county() }
When I look at the network traffic, I see these params are being sent along with the request, but they are always empty. This does not work for paging because I am loading initially with Ext.Direct (so I pass these params manually).

So where do I do wrong or can I override paging event with my own code?

Thanks in advance,
Aleksandar
