We have VF page that allows a user to upload an attachment that we later convert to FeedItem. THe VF Page also allows updating the FeedItem by inserting a new ContentVersion.
The whole thing works fine in our dev org. We have created a managed package out of it and installed it to another Enterprise edition org. The same thing however doesn't works in Enterprise edition.
Instead of updating the FeedItem, the code is creating a new Feed. We have also found that query to ContentVersion based is not returning any values.
Can you give an idea what might be causing this issue?
