We are trying to work out how to simply perform error handling within a workflow - where any implementation of a work item can detect an exception circumstance and then cause the workflow to abort with the relevant information and error handling. We currently do this by the work item handler catching the exception, setting it as an out parameter, having a split node after every step which then forks to an error handler step and then an abort step. This means more of the flow is boiler plate error handling logic than the actual important business logic - making it much harder to maintain and understand. Signals seem like they should be a cleaner way to implement this without branching and duplicate nodes for every business step.

Usually the work item is considered an execution outside the process context, so are not supposed to access the process context from there. Can you explains us a little bit about your use case? 2012/3/8 Swindells, Thomas <tswinde...@nds.com<mailto:tswinde...@nds.com>> Within a work item, if you need to signal an event how would you do it? >From a rules task you have access to the kcontext but generically this isn't >available.
