Reader.read is not a function

[xun]

I do not know how i get or how to get rid of the above error.

My little store is defined as such:


this.store = new Ext.data.JsonStore({

proxy: {
type: 'ajax',
url: this.chartUrl, //...
reader: {
type: 'json',
root: 'data'
}
},

//alternatively, a Ext.data.Model name can be given (see Ext.data.Store for an example)
//fields: ['name', 'url', { name: 'size', type: 'float' }, { name: 'date1', type: 'date'}],

dataModel: this.dataModel,
listeners: {

// load: { fn: this.handleStoreLoad, scope: this }
}
});

It shows that the request is completed successfully. However the reader stumbled somewhere.

By the way, how i can catch ajax error and data reader error seperately and provide meanful error message?

thanks

ah, found it.

should be
model: this.dataModel
not
dataModel: this.dataModel

However, the question remains:
