Question

I am trying to create a grid panel using ExtJS 4.1. It gets its data from the server using an AJAX proxy:

var store = Ext.create('Ext.data.Store', {
    model: 'myModel',
    pageSize: pageSize,
    proxy: {
        type: 'ajax',
        url: "../search",
        actionMethods:  {
            create: "POST",
            read: "POST",
            update: "POST",
            destroy: "POST"
        },
        headers: {
            'Content-Type': 'application/json'
        },
        limitParam: false,
        startParam: false,
        pageParam: false,
        extraParams: JSON.stringify({
            rows: pageSize,
            role: "Admin",
            index: myIndex,
            question: searchPhrase
        }),
        reader: {
            type: 'json',
            root: 'results.results',
            totalProperty: 'numFound',
            model: 'myModel'
        }
    }
});

store.loadPage(1);

but it doesn’t seem to work.

I get an error message saying that the JSON could not be read. What is more, in Firebug, the sent parameters are not human readable.

When I try to make an Ajax call with the same parameters, everything seems to be OK:

Ext.Ajax.request({
    url:"../search",
    method: "POST",
    params: JSON.stringify({
        rows: pageSize,
        role: "Admin",
        index: myIndex,
        question: searchPhrase
    }),
    success: function(){
        console.log("ok");
    },
    failure: function(response, opts){
        console.log("failed");
    },
    headers: {
        'Content-Type': 'application/json'
    }
});

Even in Firebug, every parameter in the request looks just fine.

What does the framework do different when using a Proxy?

It seems that it is yet another ExtJS issue.

I have found a fix here:
