    Default Uncaught exception

    Uncaught exception


    I am getting the following error in Firebug:

    uncaught exception: Ext.data.Store: Attempted to execute a write-action without a DataWriter installed.

    I have created a working Editable Grid, pulling info from the database, but am having trouble when I try to save it. I don't see anything that mentions I need to "install" the DataWriter.

    My store is setup as follows:

    Code:
    var myContactsStore = new Ext.data.Store({
        proxy : crudProxy,
        storeId: 'myContactStore1',
        reader : readerJsonMyContacts,
        // writer: minContactsWriter,
        writer: Ext.data.JsonWriter({
            returnJson: true,
            writeAllFields: false,
            encode: true,
            listful: true
        }),
        remoteSort : false,
        nocache : true,
        autoLoad : true,
        autoSave: false,
        autoCommit: false,
        baseParams: {
            method:   'post',
            min_contacts: 'load',
            format: 'json'
        },
        listeners: {
            load: function() {
                // Loaded
            }
        },
        fields: ['bus_unit','dept_id','ee_id','name','email']
    });
    Any help would be appreciated. Thanks!

    I think you just forgot the new keyword to create an instance of a Ext.data.JsonWriter.

    Code:
     
    writer: new Ext.data.JsonWriter({
            returnJson: true,
            writeAllFields: false,
            encode: true,
            listful: true
        }),

    Yes, I did miss that in my example. However, I had originally created the writer as a separate object. I think the problem there was an ordering issue, as I was attempting to create the store before the writer. Same uncaught exception either way. Fixed now though. Thanks!
