Is there an easy way (i.e., via a config element in share-config-custom.xml) to set the icon for a custom type in the document library? I'm using Alfresco 4.0. I've seen this post, but am trying to avoid modifying any original files.
No, sorry. I agree it makes sense to add though - please raise an enhancement request in JIRA. Better yet, if you're in a position to contribute a solution, we'd be very grateful!
