is there a way to get task id from expression?

[accipiter]

what i want is to get a url from a task's formkey with a taskid.

<userTask id="test" name="test" activiti:assignee="Bob" activiti:formKey="index.jsp?taskId=${someexpression}"></userTask>

is there an expression i can use to fill the task id automatically?

Hi,

I would say that Task instance is accessible from TaskListener.
(http://www.activiti.org/userguide/#apiExpressions)

Try to set variable there and use it in the expression.
