Re: [xwiki-users] Lucene defaultpage fails

Hi, I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/users@xwiki.org/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case: ... xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ... but this of course doesn't solve the problem behind. -Pete -----Alkuperäinen viesti----- Lähettäjä:
