Datastore: "Unable to load data using the supplied configuration"

[jarrednicholls]

Hey Seth,

Are you on Windows (XP or Vista/7?), OS X, or Linux? There's a local storage SQLite database you can delete to reset your settings (proxy config included). I'll give you the path to that file, depending on your OS.

Vista 7 (Pro). Sorry, I should have included that in my original post. Thanks, Jarred!

[jarrednicholls]

No worries. If you browse to C:\Users\<username>\AppData\Local\Sencha, Inc\Sencha Designer\ and delete the .localstorage file, that'll take care of clearing out your proxy config

[freshyseth]

Perfect! Thanks. The only change I had to make to your path (and it is minor) was to change:
"...\Sencha Designer\" to "...\Sencha Designer 1.2\".

Just in case anyone else tries navigating that filepath exactly. You're awesome.

I'm running into the same errors. There might be two bugs:

If the URL Prefix is set with an/ at the end and the Ajax Proxy's url with an starting / it won't work (obviously): http://www.domain.com/data/ + /users/users.json = http://www.domain.com/data//users/users.json

However: if you put http://www.domain.com/data/- in the URL Prefix and -/users/users.json in the Proxy's url, then you get: http://www.domain.com/data/-/-/users/users.json So I'm guessing Ext Designer is helping a bit too much Removing the trailing and leading / will fix this.

Second bug: https:// cannot be resolved or something like that. Putting the exact same content in a public_html 'fixes' that (logically).

I'm having the same problem...

I've created a Json.Store in XDS...

Ext.define('MyApp.store.langListStore', {
    extend: 'Ext.data.Store',

    constructor: function(cfg) {
        var me = this;
        cfg = cfg || {};
        me.callParent([Ext.apply({
            autoLoad: true,
            storeId: 'langList',
            sortRoot: 'id',
            clearOnPageLoad: false,
            proxy: {
                type: 'ajax',
                simpleSortMode: true,
                timeout: 15000,
                url: '/blog/getLang.php?limit=90',
                reader: {
                    type: 'json',
                    idProperty: 'id',
                    root: 'langs'
                }
            },
            fields: [
                {
                    mapping: 'id',
                    name: 'id',
                    type: 'int'
                },
                {
                    mapping: 'name',
                    name: 'name',
                    type: 'string'
                },
                {
                    mapping: 'roman',
                    name: 'roman',
                    type: 'string'
                },
                {
                    mapping: 'rtl',
                    name: 'rtl',
                    type: 'boolean'
                },
                {
                    mapping: 'ISO639',
                    name: 'ISO639',
                    type: 'string'
                }
            ]
        }, cfg)]);
    }
});

Using the URL in a typical browser, I see the following (sample) output:

{"total":3,"langs":[{"id":"1","name":"\u4e2d\u6587","roman":"Chinese","rtl":"0","ISO639":"ZH"},{"id":"2","name":"English","roman":"English","rtl":"0","ISO639":"EN"},{"id":"3","name":"Espa\u00f1ol","roman":"Spanish","rtl":"0","ISO639":"ES"}]}

I know the backend is working perfectly.
However, when I attempt to get Designer 1.2.2 r48 to load the data, it fails with the "Unable to load data using the supplied configuration" error.
It's worth noting that I am using Designer at a client's office behind a proxy. I had successfully managed to bypass the NTLM proxy using CYGWIN virtual environment with NTLmaps.

I'm not that experienced with ExtJS 4.x (but I'm working on it). ExtJS 3.x works with no major issues. I'm currently migrating one of my apps to ExtJS 4. I'm fairly certain my JS code above is correct.

Can someone point me in the correct direction?

ok... so, on XP the pathway is:

C:\Documents and Settings\%username%\Local Settings\Application Data\Sencha, Inc\Sencha Designer 1.2\*.localstorage

[peterversnee]

Check your project settings:

and then your stores url:

Schermafbeelding 2011-10-26 om 20.09.37.png

this should add up to http://localhost/somedir/somefile.php

Yours will add up to http://localhost/C:\Documents and Settings\%username%\Local Settings\Application Data\Sencha, Inc\Sencha Designer 1.2\*.localstorage

@peterversnee:
My reply was for the location of the SQLite DB file that Designer creates with the proxy info used to register the Designer... It's not directly related to how the Designer concatenates the preference (URL Prefix) with your store's (proxy) URL property.

C:\Documents and Settings\%username%\Local Settings\Application Data\Sencha, Inc\Sencha Designer 1.2\*.localstorage

is not the URL of a store...

[lorezyra]

The error message displays the correct full URL expected to grab the json data. And, when I click on the provided link the browser displays the json data with no errors.

So, my question remains... Why would Designer error out on loading the data? Is my store config correct?
