Hello everybody
I tried to implement Compensation Handlers according 8.5.16. Compensation Handlers.
Execution engine gives me the following error:
Compensation activity could not be found or it missing isForCompensation=“true”
Neither Web-Modeller nor Eclipse-Plugin Modeller produces BMMN XML with isForCompensation=“true” for the compensation task even though on the graphical representaion the corresponding task is marked with “<<” and associated with boundary compensation event.
Any Ideas? Thank you for help in advance.
I’m using Flowable 6.4.0 with Tomcat 9.0.13 (jdk 1.8.0_172)
Hi Roman,
I tried to create process model in web-modeler with isForCompensation flag on the master branch. Downloaded bpmn.xml has
<serviceTask id="sid-4BDF59F9-3982-48D1-A022-37810AEDC5F9" name="ServiceTask" isForCompensation="true"></serviceTask>
set. I was able to publish and run process model in the application. Could you provide more details to reproduce the issue?
Regards
Martin
Hello Martin
Thank You for you reply.
I did a small example. See below, what kind of BPMN XML is produced. I’m using the web-modeller, which I downloaded from Flowable Download page. According to war MANIFEST.MF
- Implementation-Title: flowable-ui-modeler-app
- Implementation-Version: 6.4.0
There is no isForCompensation=“true” for Payback Task.

Hi.
Could you try perform the same test with master branch? Commit https://github.com/flowable/flowable-engine/commit/86972458f55e18d591198ba8c6260367e7c5f2b3 could fix the problem.

Hello Martin,
Cannot build it from master. I used scripts/build-all.sh. It reported diverse problems, most of them related to maven/jboss configurations/dependecies.
Do you have a build system, where I can download the latest successful build (master branch)?
best regards
Roman
Compensation is working with 6.4.1.
Thank you.
