dojo Grid Json issue - json

Question

I have this code
dojo.ready(function(){
inventoryStore = new dojo.store.JsonRest({
target: "http://localhost:9080/driver/dojoMVC",
idProperty: "name",
put: function(object, options){
if(object.quantity < 0){
throw new Error("quantity must not be negative");
}
}
});
results = inventoryStore.query("");
var storeData = new dojo.data.ItemFileWriteStore({
data:dojo.fromJson(results)
});
gridLayout = [
{ name: 'Name', field: 'name', editable: true},
{ name: 'Quantity', field: 'quantity'},
{ name: 'Category', field: 'category'}];
var grid = new dojox.grid.DataGrid({
store: storeData,
clientSort: true,
structure: gridLayout
}, dojo.byId("gridElement"));
grid.startup();
When i run it i receive this strange error in FF console
SyntaxError: missing ] after element list
[Break On This Error]
([object Object])
json.js (line 26, col 9)
Can anyone help me with this?
Thanks

Answer 1

maybe you must setup your Layout like this :
var layout = [[
{name:"Id", field: "ident", width:"30%"},
{name:"Name", field: "name", width:"70%"}
]];
In Ev'ry Example i find in dojo the layout is in double brackets.
This would explain why the Error says " missing ]".
Look:
http://dojotoolkit.org/reference-guide/1.9/dojo/data/ItemFileWriteStore.html?highlight=itemfilewritestore#itemfilewritestore-changes-reflected-in-dojox-data-datagrid
Update1
so the Error lies in the store. Have you tried to fill in the data like:
results = inventoryStore.query( name : "*"); // to query all items
Have you checked it there are any results in "results"?
var storeData = new dojo.data.ItemFileWriteStore({
data:results
});
After all i would try to fill in the data without dojo.fromJson.
Give it a try.

The problem is inside the code you posted, which has a syntax error at the very end around line 26. You started with dojo.ready({ but didn't finish it with });
Here, reformatted to make it more obvious:
dojo.ready(function(){
inventoryStore = new dojo.store.JsonRest({
target: "http://localhost:9080/driver/dojoMVC",
idProperty: "name",
put: function(object, options){
if(object.quantity < 0){
throw new Error("quantity must not be negative");
}
}
});
results = inventoryStore.query("");
var storeData = new dojo.data.ItemFileWriteStore({
data:dojo.fromJson(results)
});
gridLayout = [
{ name: 'Name', field: 'name', editable: true},
{ name: 'Quantity', field: 'quantity'},
{ name: 'Category', field: 'category'}
];
var grid = new dojox.grid.DataGrid({
store: storeData,
clientSort: true,
structure: gridLayout
}, dojo.byId("gridElement"));
grid.startup();
Try adding:
});
Also, you're missing some var keywords in there.
