AbstractStore.overide error and problem locating sync storage.js

[Antony]

I have an error trying to use sencha-io with synch touch 2

I have included the scripts:

<script type="text/javascript" src="./sencha-touch-all-debug.js"></script>
<script type="text/javascript" src="./sencha-io-debug.js"></script>

and set the model configuration:

proxy: {
type: 'syncstorage', previously localstorage
id: 'local',
key: set to my sencha id name
}

Web Inspector is showing the following errors:

TypeError: 'undefined' is not an object (evaluating 'Ext.data.AbstractStore.override')
syncstorage.jsGET http://localhost:8080/myApp/proxy/sy...=1334593275931 404 (Not Found)
sencha-touch-all-debug.js:8010Error: [Ext.Loader] Failed loading 'proxy/syncstorage.js', please verify that the file exists

The browsers localstorage is updating with new records but are not displaying in components using the store.

Any help appreciated ....
