Problem adding private twitter subscription

orcmid — Sun, 11 May 2008 15:37:25 GMT

NewsGator Version: 3.0.530

The same symptoms were observed in the 3.0 public release.

Symptoms:

When adding a subscription to a private twitter RSS, such as
http://twitter.com/statuses/replies.rss
it is necessary to logon and provide a password (Basic authentication without a secure connection). The logon is apparently also the way the particular RSS feed is conditioned to deliver only those replies made to the account that is used for the logon. (The link to this feed is found on individual home pages under the "replies" tab, at the bottom left corner.)

Following provision of the user ID and password, NewsGator fails to reach the end of the Add Subscription process, popping up an unhandled exception message, with these details:

[quote]unable to cast object of type
'NewsGatorInbox.Aggregator.RSSSubscription' to type
'NewsGatorInbox.FindFeedsService.FeedInfo'.[/quote]

(the extended error detail is at the end of this post).

If I close the error message and ask the Add Subscription process to Finish, the subscription is successfully added, but at the top level under the name "Twitter / Updates replying to orcmid" rather than the folder I asked that it be placed in, renamed simpler. (I was able to move and rename the folder afterwards.)
