    Exclamation Error When Reloading GroupingStore with JsonReader

    Error When Reloading GroupingStore with JsonReader


    All,
    I have an editor grid with its store set to the GroupingStore below, the grid/store load fine on initialisation, however subsequent calls using the reload method fail.

    My code is as per below:

    The GroupingStore:

    Code:
        STORE_data = new Ext.data.GroupingStore({
            storeId: 'STORE_data',
            groupField: 'pid',
            url: 'database.editorgrid.php',
            baseParams:{task: "LISTING", start: 0, limit: 100, handler: "table1"},
            sortInfo: {field: 'id', direction: 'ASC'},
            remoteSort: true,
            reader:new Ext.data.JsonReader({
                root: 'results',
                totalProperty: 'total',
                fields:    
                [
                    {
                        name: 'id',
                        type: 'int',
                        mapping: 'id'
                    },
                    {
                        name: 'pid',
                        type: 'int',
                        mapping: 'pid'
                    },
                    {
                        name: 'name',
                        type: 'string',
                        mapping: 'name'
                    }
                ]}
            )
        });
    Within the editorgrid, the view property has been set to:

    Code:
      view: new Ext.grid.GroupingView({enableGroupingMenu: true })
    What I need to do is to change the baseparams of the groupingstore (so it loads different underlying data), and inject this data into the grid.

    The code to do this works fine when using a JSONStore:

    Code:
     STORE_data.removeAll();
            STORE_data.baseParams = {task: "LISTING", start: 0, limit: 100, handler: 'table2'}; 
    STORE_data.reload();
    However, when the above lines are called with the GroupingStore, the error:

    Code:
    e is undefined
    Is given by firebug and no data is retrieved.

    Can anyone help? Any ideas? All feeback much appreciated!
