How to get number of task sequences in queue for a Task executor?

I want to know how many task-sequences have been assigned for a task-executor at any given point of time. How can I know this?

Hi mearjun,

The total number of tasksequences are the content of node activetasksequence which is normally 1 if there are some more in the tasksequencequeue plus the ones in the tasksequencequeue. So it is content of activetasksequence plus content of tasksequencequeue.
content(node(">variables/activetasksequence",current)) + content(node(">variables/tasksequencequeue",current))

I would suggest using the standard commands instead of accessing the variable nodes:
content(gettasksequencequeue(obj))
and for the active task sequence:
objectexists(gettasksequence(obj, 0))

For me Sagar's code worked i.e. content(node(">variables/activetasksequence",current)) + content(node(">variables/tasksequencequeue",current))

Somehow Antony's code always returns 0 even if there the object has an activetasksequence.
