HelloI am currently working on an advanced workflow. After a first version running properly, now I'm trying to use a timer on different tasks of this workflow.Here is the code of my workflow :<?xml version="1.0" encoding="UTF-8"?><!– urn:jbpm.org:jpdl-3.1 –><process-definition xmlns=

I have an example of a workflow using a timer that runs an action implemented in Java. My workflow looks different than yours in its structure…here it is:


    <task-node name="reviewChangesNode" end-tasks="true">
        <event type="node-enter">
            <script>
                System.out.println("Hello");
            </script>
        </event>
        <task name="smcwf:reviewTask" swimlane="reviewer">
            <timer name="review timer" duedate="15 seconds">
                <action class="org.alfresco.repo.avm.wf.Mailer" config-type="bean">
                    <to>#{bpm_groupAssignee}</to>
                    <from>whatever@whatever.com</from>
                    <subject>New changes are ready for review</subject>
                    <text>New changes are ready for review and will be auto-approved in 15 minutes, unless you
                        review the changes and reject them.
                    </text>
                </action>
            </timer>
            <timer name="auto approve timer" duedate="15 minutes" transition="Approve">
                <script>System.out.println("Auto-Approving");</script>
            </timer>
        </task>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Suggestion - move your <event> out of the <task> block if you can, and you can still achieve what you're trying to do. Simplify the task and timer down to the simplest it can possibly be, then add more capability to it stepwise.

Thanks to brian advise, I found out where my problem come from.
It happens when I use the workflow service in my Java class.
I've replaced workflow service call in my Java class and It works fine.

Thanks to Brian for his help.
