Kaleo Workflow

[Kathryn Brewer, modifié il y a 9 années.]

Does anyone have good documentation on the Kaleo Designer and workflow within Liferay? The Liferay documentation is pretty light, and I need to develop something for our client to manage the notifications better.

Did you look at this documentation page?

Hi Kathryn,

Liferay doesn't have proper documentation for Kaleo workflow. In one of my projects, I designed workflow with notifications, task timers. Please see the below sample code for task node that contains actions, notification,tasktimer, tasktimernotifications and assignments, you can understands task node terminology while designing workflow.
