JsonRestStore Identity attribute not added when value is 0

[Phil Kaasa]

Browser: Firefox 3.0.3 and IE 7.0 OS: Windows XP SP2

Summary: If the identity property of an object has 0 as its value, the JsonRestStore? (or something it inherits from) doesn't correctly add the id property when using the fetch() method. This makes it impossible to load that data in a DataGrid?.

I have a JsonRestStore? hooked up to a REST service that returns a JSON array of objects. The identity property of those objects is the "id" property.

For reference, this is sample data that my service might return (the data given will cause the behavior I am describing):

[{

"ani": 1993, "ccrId": 1809739408, "id": -2, "dnis": 930, "firstName": "Alex", "lastName": "Anderson"

}, {

"ani": 3140, "ccrId": 26349579, "id": -1, "dnis": 7799, "firstName": "Bob", "lastName": "Roberts"

}, {

"ani": 6671, "ccrId": 516548029, "id": 0, "dnis": 413, "firstName": "John", "lastName": "Anderson"

}, {

"ani": 7818, "ccrId": 880641847, "id": 1, "dnis": 8864, "firstName": "Jean", "lastName": "Adams"

}, {

"ani": 5959, "ccrId": 1935844040, "id": 2, "dnis": 5091, "firstName": "Alice", "lastName": "James"

}]

When I view the attached HTML, the attached output is shown on the console (first 5 lines using fetch(), last 2 lines using fetchItemByIdentity()).

As you can see, when I use fetch(), the id property is not added to the object when id=0; whereas when I use fetchItemByIdentity(), the id property is added when id=0.

This is causing an "Identity attribute not found" exception when I try to load data like this into a DataGrid?. Because of the exception, the grid is stuck loading. I do not receive that exception, and the grid loads correctly if the data doesn't include any objects where id=0.

(In [16368]) Fixes #8084, handles the id property even when it is 0.
