[jboss-user] [JBoss jBPM] - Cancelling dynamically created tasks

Have such case:
in one task-node I create few tasks for different actors (every one of them has to accept processed document). This is done in node-enter event when entering this task-node.
I would like to cancel all pending tasks in this node when first of those actors rejects (takes "reject" transition). How to do this?
When I write handler for task-end event that iterates through pending tasks and calls "cancel" method I get exception that the token is locked...
simplified example of this proces:
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="Proces">
| <start-state name="start">
| <transition to="accept" name="send"/>
| <task-node name="accept" create-tasks="false" signal="last-wait">
| <event type="node-enter">
| <action name="create tasks" class="xxx.CreateAcceptTasks">
| <event type="task-end">
| <action name="is positive?" class="xxx.AcceptTaskEnd">
| <task name="accept"></task>
| <transition to="accepted" name="accept"></transition>
| <transition to="rejected" name="reject"></transition>
just creates TaskInstances of "accept" Task and assignes them to actors provided in param.
when I tried to fetch pending tasks with executionContext.getTaskMgmtInstance().getTaskInstances()
and then call "cancel" on every pending tasks (that is not equal to current task of course) - I get "Token locked" exception...
Any help would be appreciate...
