For example Sam DerKazaryan of Isobar Global asked me recently for an Instantiation Action to increment the issue number on newly created issues. For those of you who like a spot of programming with their process engineering, here's the code snippet that does it...
#root = getPersistenceHelper().getRootExchangeElementContainer(),
#counter = #root.getIntProperty("currentCounterValue"),
#counter = #counter + 1,
setName("Issue " + #counter),
Note: you need version 2.7.2 of xProcess or later to run this code.
