Jakub, Stephen I am almost 100% sure that there's already (at least?) one Jira issue for this problem (and no, I don't have its number to share with you ... ;-)). If so, can you please add your findings to this issue(s) for the sake of completeness.
Thanks Werner PS If there's more than one issue, can you please link there using the Link command in Jira. Makes life easier when starting to work on a patch for this particular problem. > --- Ursprüngliche Nachricht --- > Von: "Jakub Milkiewicz" <[EMAIL PROTECTED]> > An: [email protected] > Betreff: Re: [castor-user] hashtable mapping with interface > implementations > Datum: Thu, 13 Apr 2006 10:21:15 +0200 > > Hi Stpehen > I followed your advice and it works. > If you try to find solution for the problem, another hint :I am using > castor > 0.9.9.1. > Thanks for your reply > > > > 2006/4/12, Stephen Bash <[EMAIL PROTECTED]>: > > > > Jakub- > > > > I've also observed this problem in the past few months with Castor. > > Unfortunately I haven't had time to track down a source of the > > problem.
