[xwiki-devs] Failed the start Generic Installer XWiki as of Today

12 Aug 2009

      Hi

I just checked out platform (core SVN revision: 22631) and enterprise, built it and installed the Generic installer XWiki. While starting it up I saw this exception:

Can't figure out what is wrong but it seems to be an issue with the Execution not be set on the DefaultRemoteObservationManagerContext or the Execution.getContext() returns null.
