Googled my problem and found the exact problem but with no answers.
After the upgrade to Winter '15 / Package.xml to 30.0, there are errors on my profiles
Error: profiles/PROFILENAME.profile(12101,24):In field: layout - no Layout named FeedItem-Feed Item Layout found.
So I added the layout to my package.xml and project, and now I have a new error
Error: layouts/FeedItem-Feed Item Layout.layout(FeedItem-Feed Item Layout):Layout must have at least 1 section
I have not been able to locate anywhere in the browser UI that this specific layout can be configured. The only option I see is to get rid of the layout from my project/package, refresh profiles from Salesforce server, delete the below-mentioned few lines of XMLs from each profile XML file and then deploy.
<layoutAssignments> <layout>FeedItem-Feed Item Layout</layout> </layoutAssignments>
Am I the only one facing this problem? Isn't there any way I can simply refresh the profiles and deploy without interfering with the XMLs?
