[jbpm-users] [JBoss jBPM] - cancel timer failed...

hi all, i am learning the lates PVM source code these days. i've created a timer which will call signal to of the host execution to change the normal flow. the process is like this: start --> do some --> schedule(timer)&wait ---> timeout state ---> ... | | | + -----------> signal to cancel timer --->.... the problem is that, when i cancel the timer(call TimerSession#cancel(timer)), then exception cames out: org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [org.jbpm.pvm.internal.job.TimerImpl#26] i thought that i have to remove the reference of the to-be-removed-timer by the Execution instance first, then i call TimerSession#cancel(timer), but i can not find any API to remove a timer from an execution. or i should modify the 'cascade' attribute in the hibernate configuration file of the class 'Execution'? but i'm affraid that the modification like this would bring more unknow mistake. or i am totally wrong? appreciate!!
