    Default Extjs4 Grid Report Error: reader is indefined


    I am facing an issue while trying to generate multiple grids in EXTJS 4. I am facing this issue only while pulling up a grid for the 3rd time. (Either when I load 3rd grid in the same page or when I load the 3rd grid in different tabs within the application). The first 2 grids come fine but the third grid is the one that fails with the below message

    reader is undefined:

    if (reader.isReader) { ext-all-debug.js (line 25941)

    I am using the following code to define the reader.

    //Define a reader for the XML file
    Ext.define('GridReader', {
    extend: '',
    fields: XMLFields
