    Ext js gridpanel reconfigure is displaying the column headers jumbled


    Im having the ext js grid panel 4.0,
    im loading the columns and store dynamically on to it, on select event of a combobox,

    the headers are displayed properly when we load it for the first time ,

    however for the consecutive combo value selections, the headers are not displayed properly,

    I've tried following options:
    doLayout(), view refresh, on Grid objects with no luck.

    i would be of great help if someone can give some pointers for this problem

    Grid View definitions in form:
    {
    xtype: 'iq_gridpanel',
    id: 'inserSFsecRolesGrid',
    columns: [{ name: 'Loading...', type: 'string', locked: true}],
    cls: 'dirtyCellFalse',
    columnLines: true,
    stateful: false,
    }

    Code for constructing the model fields and loading store for the grid:
    var myFields = [];
    for (var i = 0, len = r[0].raw.columnInfo.fields.items.length; i < len; i++) {
    var field = r[0].raw.columnInfo.fields.items[i];

    var this_field = {};
    if (Ext.util.Format.lowercase(field.dataIndex) == 'memberid') {
    this_field['name'] = 'memberid';
    this_field['type'] = 'string';
    }
    else if (Ext.util.Format.lowercase(field.dataIndex) == "secicon") {
    this_field['name'] = 'secicon';
    this_field['type'] = 'string';
    }
    else if (Ext.util.Format.lowercase(field.dataIndex) == "displayname" || Ext.util.Format.lowercase(field.dataIndex) == 'name') {
    this_field['name'] = 'displayname';
    this_field['type'] = 'string';
    }
    else {
    this_field['name'] = field.dataIndex;
    this_field['type'] = 'bool';
    }

    myFields.push(this_field);
    }


    var store2 = Ext.create("Ext.data.Store", {
    fields: myFields
    });


    debugger;
    Ext.getCmp("iq_insertSF_windowpanelid").items.items[1].btn.show();
    store2.loadData(r[0].raw.GridData);
    r[0].raw.columnInfo.fields.items[1].renderer = renderSecurityIcon;
    var columnInfo = r[0].raw.columnInfo.fields.items;
    var hdrObj = Ext.grid.header.Container(columnInfo);
    secRolesGridObj.reconfigure(null, hdrObj);
    // secRolesGridObj.query('panel')[0].componentLayout.initialized = false;
    // secRolesGridObj.query('panel')[1].componentLayout.initialized = false;
    // secRolesGridObj.query('panel')[0].doLayout();
    // secRolesGridObj.query('panel')[1].doLayout();
    //secRolesGridObj.bindStore(store2);
    secRolesGridObj.doLayout();
    secRolesGridObj.getView().refresh();

    Thanks
