Arrays in JSON interpreted as strings

[edgarmv]

Hi.

I have encountered a problem where my JSON responses, returned by the server, are being improperly parsed. JSON responses such as:

{
    "response": {
        "status": 0,
        "startRow": 0,
        "totalRows": 2,
        "data": [{
            "email": ["Server network", "DNS resolver"]
        }, {
            "email": ["Wifi", "Client network"]
        }],
        "endRow": 1
    }
}

will give me two records, each containing a string("Server network,DNS resolver" and "WiFi,Client network") for the email DataSourceField.

However, if i change the server to send responses in XML, such as this :

<?xml version="1.0" encoding="UTF-8" ?>
    <response>
         <status>0</status>
         <startRow>0</startRow>
         <totalRows>2</totalRows>
         <data>
             <rule>
                  <email>Server network</email>
                  <email>DNS resolver</email>
             </rule>
             <rule>
                 <email>WiFi</email>
                 <email>Studentby</email>
             </rule>
         </data>
         <endRow>1</endRow>
     </response>

I will get two records containing arrays(["Server network", "DNS resolver"] and ["WiFi", "Client network"]) in the email field.

Why is this?

I have seen in the docs that you parse JSON responses with JavaScripts eval() function. Running eval() on the JSON response above will give me the correct result. I have tried to located the problem in transformResponse(), but even doing a JSONObject(dsResponse.getDataAsObject()).toString()) gives the wrong result.

Test case:
rules.py will return the XML response above, and rules2.py will return the JSON response above.

public void onModuleLoad() {
        
        VLayout layout = new VLayout();
        
        layout.setHeight100();
        layout.setWidth100();
        
        RestDataSource ds = new RestDataSource();
        RestDataSource ds2 = new RestDataSource();

        DataSourceTextField dataSourceTextField = new DataSourceTextField("email");
        dataSourceTextField.setMultiple(true);

        ds.setFields(dataSourceTextField);
        ds.setDataURL("rules.py");

        ds2.setFields(dataSourceTextField);
        ds2.setDataURL("rules2.py");
        ds2.setDataFormat(DSDataFormat.JSON);
        
        ListGridField listGridField = new ListGridField("email", "Email alert");
        ListGrid grid = new ListGrid();
        grid.setDataSource(ds);
        grid.fetchData();
        grid.setFields(listGridField);

        ListGrid grid2 = new ListGrid();
        grid2.setDataSource(ds2);
        grid2.fetchData();
        grid2.setFields(listGridField);

        layout.setMembers(grid, grid2);
        layout.show();
    }
}

Then in the developer console, one can do isc_ListGrid_1.getRecord(1)["email"] and isc_ListGrid_1.getRecord(1)["email"] to see the differences.
