I'm trying to add a video to the users Favorites and I'm getting error
code 501.

Here is the output in the console.
2009-04-23 21:00:34.021: Error Error
Domain=com.google.GDataServiceDomain Code=400 UserInfo=0x17a9deb0

2009-04-23 21:00:34.030: Invalid parameter not satisfying: aString !=

and this is how I'm adding.
GDataEntryYouTubeVideo *object = [results objectAtIndex:[resultsTable
selectedRow]];

And this is the xml of entry

I've tried to get the current gdata-objective-c from svn and it didn't
fix it.

Thanks for the help,
Mr. Gecko

If I'm remembering right there are some updates to the YT classes for newer features, so updating could have cause slightly different request to trigger the change in result code.

I can't say I'm very familiar with the YT api, you might want to try also posting your XML to the YT API group, as they can better speak to specifics of the server and API.

The code in this message for adding a YouTube favorite still works for me:

http://groups.google.com/group/gdata-objectivec-client/msg/be6c031a17790535

The "noPostConcurrency" error message is surprising. It implies that there is a header for the POST specifying that the ETag string should of the new entry be compared to the ETag of an entry already on the server, but that makes no sense for an insert operation, because a new entry is being uploaded. The http log included above does not also include the headers for the XML being posted, however, so I'm not certain what is being sent to the server.

I'd set a breakpoint in GDataServiceBase's method -requestForURL:ETag:httpMethod: to see what is being added to the POST header.

confirm. still working solution! great!

Is there any way to check if a video is in favorite playlist?

I don't want to to scan the entire feed looking for a videoID....
