Process Parsing to add task listeners

mprakash — Mon, 19 Jun 2017 16:54:20 GMT

I am trying to hook into process parsing to add task listeners to all tasks. I tried the following config: <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration"> ... <property name="postBpmnPar

If your class is not even instantiated at all then it stands to reason that some Spring configuration may be overriding your configuration of the postBpmnParseHandlers property, otherwise Spring would have to call the constructor of your class.

That was user error-I wasn't flushing the file. Adding log.flush() fixed that.

However, I still haven't solved the basic problem--I want to add a listener to all User and Script tasks, which should get called upon entry and exit to the task, so I can generate some events. Ideally, this should be done automatically on all processes when they are parsed, so the definition creator does not have to manually add the listeners to each task.

What is the best way to do that? I can add listeners in the designer, but how can I do it programmatically? The parsing hook does see to have a way to do that.

Thanks.

I found a possible solution in one of the threads, but it only partly works. It seems that ((ProcessDefinitionEntity) bpmnParsegetCurrentScope().getProcessDefinition()).getTaskDefinitions() is non-empty only for User Tasks. For Service and Script Tasks, it is an empty collection.

What will be the best way to attach a listener to all task nodes in a process definition at parsing time?#processparsing

Any answers are greatly appreciated.

BTW, I am using Activiti 5.22 (CE).

Thanks.
