[rules-users] Timer Event Node and Persistence

[jschmied]

Hi!

Playing around I created a ruleflow with a timer event. When the timer is
firing and I try to persist the ruleflow the timer keeps fireing and I get
the following exception:

I think the timer calls object in the disposed session?
How do I stop the timer event before disposing the session?
Should the timer run again after reloading the ruleflow? (Couldn't get so
far)


Thanks
