I forgot, there is a possible workaround : remove the "&& !$mships.contains($sp)" part of the conditional statement for displaying public and open spaces. The drawback is that can have spaces listed twice : both as a membership and as public or private. If you still have the trace after that, try removing the "!$sp.equals($org) && !$sp.equals($myspace)" part too, as it potentially can raise the issue too. If you still have the trace, then... let me know :) Jerome. >> >> -Jarmo >> >> >>> >>>> Where I can find XWS.MySpaces?
