OK, that is tilting.... i published the code, if any good soul can help me and take a brief look... http://code.google.com/p/vike/
The logic is now reduced to: 1) MailHandler receives inboud mail, extracts content and delegates to new DM() 2) DM finds the game, according to email recipient, and takes action. 3) Before and after findGame(), it creates and persist a simple entity (Actor) Here is what happens - The BEFORE entity is persisted sometimes - The AFTER entity is never persistend - If i change the code to the mail handler class, it works. - No error is logged The relevant code : Mail Handler - http://vike.googlecode.com/svn/trunk/vike/src/br/com/ximp/vike/server/MailHandler.java DM - http://vike.googlecode.com/svn/trunk/vike/src/br/com/ximp/vike/server/DM.java Actor - http://vike.googlecode.com/svn/trunk/vike/src/br/com/ximp/vike/server/model/games/ww/Actor.java Thanks in advance On Oct 30, 12:07 pm, John Patterson <[email protected]> wrote: > I believe this exception is normal and not a problem.
