When the asset publisher includes web content and is set to "viewInContext" then the rss feed returns zero content.
from what I see I think the getEntryURLViewInContext method in com.liferay.portlet.assetpublisher/actionRSSAction.java should be passing something othe rthan null in this call:
String viewInContextURL = assetRenderer.getURLViewInContext(
the asset publisher jsp files all pass the viewFullContentURLString instead of null.
My hunch is that journal content actually uses that string to create the viewinContextURL
I believe this is still happening in latest builds (looking at SVN).
only happens if web content is included in the asset publisher entries displayed.
