Disabling shell service tasks?

Flowable Engine
#1

Hi there,
is it possible to configure the Engine to raise an error when Service Tasks of a certain type (say, ‘shell’) are declared?

Thanks!

#2

Hi,

Yes, it is possible. Just replace shell task behavior in the behavior factory.

Thank you very much, I’ll give it a try.

Can you point out to some code sample?

If I got it right, I should be setting my own subclass of org.flowable.engine.impl.bpmn.parser.factory.DefaultActivityBehaviorFactory in my configuration via setActivityBehaviorFactory().

What should be the method body of the override method in my own class, instead of https://github.com/flowable/flowable-engine/blob/93748d3f139840d246312819a0570db3f485280d/modules/flowable-engine/src/main/java/org/flowable/engine/impl/bpmn/parser/factory/DefaultActivityBehaviorFactory.java#L324-L329 if I just want to reject?

Hi,

That’s one possibility. Another is to use your own custom parser and change behavior when process definition is parsed. https://flowable.com/open-source/docs/bpmn/ch18-Advanced/#hooking-into-process-parsing

If you want to throw an exception (BPMN error, increase counter, send email… ), do it.
