Bug in datajs beta2 1.1.1?

Jul 9, 2013 at 12:03 PM
Hi guys:

I get an error when using the new datajs 1.1.1 beta2:

This worked before.
Here is the code:

-->Cannot set property 'contentTypeOdata' of null"
var sURL1 = "http://services.odata.org/(S(readwrite))/OData/OData.svc/$metadata";
var sURL2 = "http://services.odata.org/(S(readwrite))/OData/OData.svc/Products?$expand=Category";

var oRequest = { 
            requestUri : sURL1,

OData.read(oRequest, function(oMetadata){

    var oRequest = { 
            requestUri : sURL2,

OData.read(oRequest, function (oData) { 
       alert (oError.message);

}, function(oError){
       alert (oError.message);
}, OData.metadataHandler);
This happens only when I read the metadata first and hand it over to the next request and when using the expand property...

Crash happens in jsonLightReadObject:
var propertyValue = data[name];
                var propertyModel = jsonLightDataItemModel(name, dataModel);
                var isNavigationProperty = jsonLightIsNavigationProperty(name, data, propertyModel);
                var propertyType = jsonLightDataItemType(name, propertyValue, data, propertyModel, model);
                var propertyMetadata = propertiesMetadata[name] = propertiesMetadata[name] || { type: propertyType };
                if (isNavigationProperty) {
                    var propertyInfo = {};
                    if (objectInfo.entitySet !== undefined) {
                        var navigationPropertyEntitySetName = lookupNavigationPropertyEntitySet(propertyModel, objectInfo.entitySet.name, model);
                        propertyInfo = getEntitySetInfo(navigationPropertyEntitySetName, model);
                    propertyInfo.contentTypeOdata = objectInfo.contentTypeOdata;
propertyInfo is null
Could you please check this?

Hi Joe,

Thanks for reporting the issue.
It happens when there you do a request for json with fullmetadata and there is type inheritance on the type like your case it fails on the FeaturedProduct entity.
This will be fixed in the 1.1.1 release.
