Is there any event mechanism acts on TaskVariable?

[swamy2156]

Currently, I am suspending and resuming tasks using a TaskVariable(a.k.a form property) . During task creation time, taskvariable is set to "ACTIVE" and changing it to "SUSPEND/RESUME" based on certain conditions of its lifetime. I would like to trigger an event when task variable is changed to "SUSPEND" or "RESUME". Does Activiti support event mechanism on task variable value change?? If Yes, Please suggest. (any work around also welcomed)

Thanks,
Swamy.

I do not know about such a mechanism.
work around:
You can have a look on org.activiti.engine.impl.history.HistoryManager#recordVariableUpdate method. Method is invoked each time when variable is updated. You can be inspired from it to implement your own hook.
