SW - make process exception accessible using an expression within SW definition

[deepakkapoor23]

Description

Currently there is no way of accessing the last process exception if any and pass it along to a state for custom handling.

Please expose exception object stored in KogitoProcessContext::getContextData().get("Exception") as $WORKFLOW.ERROR to be referenced elsewhere in the workflow.

Also, ProcessEventListener::onError should be called not just for unhandled errors but for all errors including the ones handled with onError block in SW

Implementation ideas

@fjtirado do you think its an easy change (to expose workflow exception as $WORKFLOW.ERROR) in the meantime until the new spec is implemented?

Without this provision in the current spec, there is no way of knowing what the error was (if its already handled), its not even logged.
