This is my process definition which describes the process of creating tasks, assiging tasks and then completing tasks.
I now need to be able to assign/re-assign tasks any number of times.
So the 'assign action' state-node needs to be called as many number of times.
How should i change my process definition to iterate through the same node.
Should i introduce a decision node above my 'assign action' state-node where i make a decision to either assign an action / complete an action .
If assign actin is chosen i tranistion to assign action node and propogate execution back to the decsion node where it waits.
Should this be my approach , please suggest ?
