Adding TaskListener in custom BpmnParseHandler

jwojtczak — Fri, 26 Jul 2013 06:38:20 GMT

Hi,I'm trying to add TaskListener to UserTask in custom BpmnParseHandler. I implemented BpmnParsehandler interface and added my TestBpmnParseHandler to the processEngineConfiguration bean. <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">

No, that won't work, because at that point the parsing is already done. I agree, the name 'preparsehandler' does seem to indicate that.

Here's an example of how you need to do it: https://github.com/jbarrez/activiti-advanced-scripting/blob/master/src/test/java/org/activiti/ExecuteScriptOnTaskCompleteBpmnParseHandler.java

Hello,

currently I am working on the transformation of the old BpmnParseListeners to the BpmnParseHandlers.

I was facing a similar problem, that is how can I add ExecutionListeners to certain tasks and processes? I found your example here in the forum and tried to do it like that, but the BpmnParse is empty and it's currrentXXX members are null.

    protected void executeParse(BpmnParse bpmnParse, Process element) {
        for (IConfigurableExecutionListener listener : m_executionListeners) {
            if (listener.supportsProcess()) {
                bpmnParse.getCurrentProcessDefinition().addExecutionListener(listener.supportedEvent(), listener);
            }
        }
    }

What did I do wrong?

I added the parse handler to the "preBpmnParseHandlers".

I use Activiti 5.22.0

Do you have some more detailed examples how to do the transformation from ParseListeners to ParseHandlers? Actually I am not sure how to use the parameters BpmnParse and Element correctly.

I tried adding a parse handler following the above example, but ((ProcessDefinitionEntity) bpmnParsegetCurrentScope().getProcessDefinition()).getTaskDefinitions() is an empty hash table. I tried both pre and postBpmnParseHandlers.

What am I doing wrong?

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?‌
