Knut Wannheden commented on HIVEMIND-155: ----------------------------------------- James, "Support" is probably the wrong term. But it's certainly not nice to have HiveMind enter an endless loop trying to construct this service. I think it would make sense if HiveMind detected this and reported an error. What do you think? > Infinite Recusion Issue When Creating a Service > ----------------------------------------------- > > Key: HIVEMIND-155 > URL: http://issues.apache.org/jira/browse/HIVEMIND-155 > Project: HiveMind > Type: Bug > Components: framework > Versions: 1.1 > Environment: Windows XP > Reporter: Jean Safar > > I am experiencing a problem by which HiveMind (version 1.1 and 1.1-beta-3) > will enter into a infinite recursion when creating a service.

I have tried that and it works fine. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
