Description (last modified by )
Run the following code on Android 3.x (at least Samsung Galaxy Tab 10.1 tablet):
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<script type="text/javascript">
dojoConfig = {
isDebug: 1,
parseOnLoad: 0,
async: 1,
mvc: {debugBindings: 1}
};
</script>
<script type="text/javascript" src="../../../dojo/dojo.js"></script>
<script>
require(["dojox/mvc/StoreRefListController", "dojo/store/DataStore", "dojo/data/ItemFileWriteStore"],
function(StoreRefListController, DataStore, ItemFileWriteStore){
var ctrl = new StoreRefListController({store: new DataStore({store: new ItemFileWriteStore({url: "lists.json"})})});
ctrl.queryStore();
});
</script>
<script type="text/javascript">
</script>
</head>
<body>
</body>
</html>
You will get an exception.
This seems to be coming from the fact StoreRefController is adding new properties on a Deferred promise while the promise has been frozen (Object.freeze). Other browsers seems not enforce that but Android 3.x does.

Sorry for the typo. I only have one Android 3 device (the one listed above), so maybe this is specific to this one. I say this is coming from the frozen objects for two reasons:
- because a TypeError: object is immutable error is indeed shown in the console (and this happens in StoreRefController.queryStore when we copy new properties into the promise)
- and because if I change Deferred code to not freeze the promise I don't have anymore the problem ;)

IIRC module named dojox/mvc/StoreRefListController does not exist... So tried slightly modified HTML like below:
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8"> <script type="text/javascript"> dojoConfig = { isDebug: 1, parseOnLoad: 0, async: 1, mvc: {debugBindings: 1} }; </script> <script type="text/javascript" src="/path/to/dojotoolkit/dojo/dojo.js"></script> <script type="text/javascript"> (function(){ require([ "dojo/json", "dojo/when", "dojo/store/DataStore", "dojo/data/ItemFileWriteStore", "dojox/mvc/EditStoreRefListController" ], function(json, when, DataStore, ItemFileWriteStore, EditStoreRefListController){ var ctrl = new EditStoreRefListController({store: new DataStore({store: new ItemFileWriteStore({url: require.toUrl("dojo/tests/data/countries.json")})})}), promise = ctrl.queryStore(); when(promise, function(data){ console.log("Obtained: " + json.stringify(data)); }); }); })(); </script> </head> <body> </body> </html>And got the following (without an error) with Android 3.0 browser:
Obtained: [{"abbr":"ec","name":"Ecuador","capital":"Quito","id":"ec"},{"abbr":"eg","name":"Egypt","capital":"Cairo","id":"eg"},{"abbr":"sv","name":"El Salvador","capital":"San Salvador","id":"sv"},{"abbr":"gq","name":"Equatorial Guinea","capital":"Malabo","id":"gq"},{"abbr":"er","name":"Eritrea","capital":"Asmara","id":"er"},{"abbr":"ee","name":"Estonia","capital":"Tallinn","id":"ee"},{"abbr":"et","name":"Ethiopia","capital":"Addis Ababa","id":"et"}]I haven't worked much with Android, so wondering why you thought it's an issue with accessing frozen object? Was it from console or something?
