Description
The documentation in http://docs.dojocampus.org/dojo/data/ItemFileReadStore is either wrong or incomplete when it touches on updating a data store by "A new call to fetch will invoke the URL load or reparse the data object into a new list of items."
There is also a lot of noise and confusion about updating a data store, making this information very costly.
dataStore.close() and .fetch() will not refresh the dataStore created from a jsonData object ..unless dataStore._jsonData is first refeshed:
dataStore.close(); dataStore._jsonData = dataObject; // dataStore.fetch();
Also, dataStore.fetch() has no effect and may not be necessary when the data store is fed from a jsonData object.
The test code follows:
<html>
<head>
<title>DataStoreTest</title>
<style type="text/css">
@import "http://o.aolcdn.com/dojo/1.3/dijit/themes/tundra/tundra.css";
</style>
<script type="text/javascript" src="http://o.aolcdn.com/dojo/1.3/dojo/dojo.xd.js"
djConfig="parseOnLoad:true, isDebug: true">
</script>
<script type="text/javascript">
dojo.require("dijit.form.FilteringSelect");
dojo.require("dojo.data.ItemFileReadStore");
var dataObject = {
identifier:"name",
items:[{name:"Name-1"},{name:"Name-2"},{name:"Name-3"}]
};
var count = 3;
var selector;
var dataStore;
dojo.addOnLoad(function(){
dataStore = new dojo.data.ItemFileReadStore({data:dataObject, clearOnClose:true});
selector = new dijit.form.FilteringSelect({
id: "SelectBox",
value: dataObject.items[0].name,
store: dataStore,
searchAttr: "name",
name: "dojo",
}, dojo.byId("SelectField"));
});
function updateStore(){
dataObject.items.forEach(function(item){
count++;
item.name = "Name-" + count.toString();
console.log(item.name);
});
console.log(dataStore);
dataStore.close();
dataStore._jsonData = dataObject;
// dataStore.fetch(); // dataStore updates without this call
console.log(dataStore);
selector.store = dataStore;
}
</script>
<body class="tundra">
<input id="SelectField">
<button onClick="updateStore()">Update</button>
</body>
</html>}}}

Okay, I've updated IFS to make this simpler to do and updated the documentation on: http://docs.dojocampus.org/dojo/data/ItemFileReadStore to reflect this. The data example currently fails, but that is because I need the dojo version on campus updated before it will work. Closing this ticket as fixed.
