    [CLOSED] problems loading Store similar to how coolite does for static data

    I'm trying to simulate the coolite store that is created and am having troubles. I keep getting an "object not found" on the store creation. The offending code is below, and I've also attached my example code that is a complete failing stand alone html file (js with tags).
    
    
    
    var sessionData = [

    RE: [CLOSED] problems loading Store similar to how coolite does for static data

    Hi Piter,

    The Ext.data.PagingMemoryProxy is non ExtJS standart class. Stamdarts ExtJS js files don't include this class. This class placed in separated file. If you have ExtJS distributive then you can find it in

    ext-2.2\examples\locale\PagingMemoryProxy.js

    Please note that Ext.data.PagingMemoryProxy which was included to the Coolite Toolkit is differ than standart PagingMemoryProxy (there are few changes).

    The coolite version of file you can find in Coolite distributive

    Coolite.Ext.Web\Build\Resources\Coolite\coolite\co olite-data.js

    Hope this help

    Thanks,

    Now I don't get the error, but my data is not getting loaded. I've included in the below code what I have updated my code to. (I also used the coolite store. I assume that is necessary?)

    Hi,

    The GridPanel store property requires store object but you set a string. Try remove quotes

       change  - store: 'ctl00_blankContent_Store1'
       by - store: ctl00_blankContent_Store1,

    still, after unquoting the store, I get no data. :(

    Hi Piter,

    I found only one problem - trailing comma in your Data array (IE hates trailing comma and brokes).
    After removing this comma your example works without errors and data displayed.

    Change
    
    "Id": 2
    },
    By
    
    "Id": 2
    }

    One useful tool which you can use for check your javascript code

    http://jslint.com/

    Hope this help.

    Let me know if the example still doesn't work

    Thanks Vladimir,

    This worked for me! My bad. It was a cut and paste error on my part. I will definitely start using jslint. Thanks for the tip.

    Hillarious.

    The answer was looking right at you the whole time...

    I didn't know that. He's spoken at our last 3 code camps. He works at Yahoo and has been a huge help to making the event successful. Our all volunteer event was just last week and he had about 250 people in his sessions. He likes to grab the first two sessions Saturday morning and does not stop for a rest in the middle.

    It was not, until very recently, been at all interested in JavaScript. Now I see how big a person he is in the JS community. Next year, I'll have to bring him water. :)
