Steps to reproduce:
- Create simple WikiPageLocalServiceWrapper
- Deploy WikiPageLocalServiceWrapper and test if it is working
- Change an option in "Control Panel" > "Configuration" > "System Settings" > "Collaboration" > "Wiki Service"
- test WikiPageLocalServiceWrapper again > it's not working anymore
There is no error message. Changing the configuration of other modules does not affect the WikiPageLocalServiceWrapper. Other ServiceWrapper (e.g. BookmarksEntryLocalServiceWrapper) work fine after changing the configuration of the corresponding module ("Bookmarks Service" in this case).
