Hi,

It’s hard to guess what is going on. I would say that the problem is in the process model.

Hi Japelleg,

I am trying with customizing pallete.I was extend the pallete succesfully but facing the similar issue when validating the workflow.Kindly guide me in sorting the issue.

The fact the sequence flow validator isn’t seeing it as a real ‘task’, it means probably it isn’t registered as such. Can you share a bit how your palette elements looks like?

Hi Martin,

For adding custom task I had followed these two steps:

  1. Add new node to stencilset_bpmn.json. After this step new node is added to modeler paletes.
    2)Implement json -> bpmn and bpmn -> json converter and add it to the converters.
  2. Generate jar for the flowable ui and deploy the same in tomcat.
