Ok I think now I get it. :) What about acutally changing some persistent attribute on the object ? Would that work ?

Basically you can't. Although if a thread doesn't wake up for 10 mins (with your object), then odds are it'll get thrown out and brought back in again without the _v_ attributes set, so it's probably a moot point. You would have to grab each ZODB connection present, grab your object and call the method.. That's just getting in voodoo you probably don't actually need. The best you could do would be to set a flag / timestamp. Any object that woke up would have to check that timestamp and work out whether to flush at that point or not. | Or do you mean that clearCaches() should do the self._p_changed=1 ? _p_changed = 1 won't flush your _v_ attributes. -- Andrew Milton akm@theinternet.com.au _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
