How to set businessKey to sub process when use the call activity?

ssun — Wed, 07 May 2014 21:45:48 GMT

The call activity can pass input variables from parent to child process, but I want to set the businessKey of the child process to query it easily.Currently I can set the businessKey as a variable of the child process and query on that but it is not the real businessKey and the query is a complicate

Good point. We can make this available as a new attribute on the call activity. Could you raise a JIRA for this?

Best regards,

How do I register on the codehaus website JIRA system? Do I need to email someone?

That is awsome prakie! I wonder when will this code change will be in the product.
Also I suspect some user would want it to be an option to whether inherit the businessKey from parent process or not.
Or someone may go crazy ask for some transformation functionality for example:
parentBusinessKey: parent1
childBusinessKey: parent1child1
