Uncaught exception

[arcticweb]

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:

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.

 
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!
