[tania_bernal_ssss_gouv_qc_ca]

Hi JIRA community,

I want to change workflow transition .

I saw that its impossible but i want to be sure.

Big thank you

//type is subtask

else if (issueContext.issueType.name == "Intervention(s) /Sous-tâche") {

           // test and works, get parent workflow

           def status = getUnderlyingIssue().getParentObject().getStatus().getName()       

          // finaly put in on the form ????
          CurrentWorkflow = setParentWorkflow

}
