During our research on jBPM5, we could not find out if it supports the multiple (loop, sequential or parallel) attribute on a call activity node, can someone advise how to achieve this?
If it is not supported now, will it be in a future version?
This special case is not supported yet, but you can use the call activity / resuable sub-process in a multi-instance sub-process. Note that a multi-instance sub-process can execute sequential only yet. (see http://docs.jboss.org/jbpm/v5.3/userguide/ch.core-basics.html#d0e1926)
