Have a strange problem when querying for an entity. I'm trying to query on "topic_id" (which is a valid field), but DataStore.find() does not return it.



Here's the row:

http://dl.dropbox.com/u/68704/Screenshots/s38f.png



And my query that doesn't



var subTopicsQuery = new $kinvey.Query();

subTopicsQuery.equalTo('topic_id', '5333298a24aabbb96746ad47');

return $kinvey.DataStore.find('subtopics', subTopicsQuery); // returns []



And the query that does:



var subTopicsQuery = new $kinvey.Query();

subTopicsQuery.equalTo('name', 'UX Lead');

return $kinvey.DataStore.find('subtopics', subTopicsQuery);



I'm replacing 5333298a24aabbb96746ad47 dynamically in my app, but it doesn't work harcoded either.

To your point OhmzTech: how would I structure the KinveyRefs when I'm using custom BL? I don't see any modules that let you do that from the server side - unless I'm missing something.

OhmzTech, you're definitely right. I should use relations, but figured I'd try it this way first.



Mark, I'll give that a shot.

It looks like the `topic_id` is saved as a *ObjectID* instead of string. How did you create these particular documents?



If you saved them through BL, I recommend using the [collectionAccess.objectID](http://devcenter.kinvey.com/reference/business-logic/reference.html#collection-access-module) method to make sure the value is a string, and not an object.



We are aware of the confusion around Object IDs / strings, and we are in the process of moving to strings only. So, in the future, this won’t be a problem anymore.

Did you try running the query in the console API and see if it works there?



It sounds like "topics" is a collection, any reason you aren't just using relations / kinveyRefs for this?
