I am using Liferay checkout from trunk on the 13th of November. When I Enable RSS Subscription, the feed button is available as expected and the feed is read correctly by mac safari browser. However, the feed generated is not accepted by Facebook as external source because of format problem. When tested for validation using www.feedvalidator.com, the error report is that the id for the entries are not valid ("id must be a full and valid URL"). The problem is that the id automatically generated for each entry in the feed does not have the full URL. E.g.
instead of generating
what is generated is
This is not accept by some feed readers.
