Hi @Ramesh Lakshmanasamy,

Please take a look at: 

• https://docs.atlassian.com/software/jira/docs/api/7.11.0/com/atlassian/jira/workflow/WorkflowTransitionUtil.html

Example code;

WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) JiraUtils.loadComponent(WorkflowTransitionUtilImpl.class);

Map params = new HashMap();
String comment = "abc"
params.put(IssueFieldConstants.COMMENT, comment);

workflowTransitionUtil.setIssue(issue);
workflowTransitionUtil.setUserkey(userKey);
workflowTransitionUtil.setAction(111);
workflowTransitionUtil.setParams(params);
workflowTransitionUtil.validate();
workflowTransitionUtil.progress();

It doesn't work.

Since I was on the search myself, I found this solution (tested with Jira 8.3.0 and 8.3.1):

IssueService.IssueResult transResult;
IssueInputParameters issueInputParameters = new IssueInputParametersImpl();

TransitionValidationResult validationResult =
issueService.validateTransition(workflowuser, issue.getId(), actionDescriptor.getId(), issueInputParameters);

if (validationResult.isValid()) {
   transResult = issueService.transition(workflowuser, validationResult);
}

What you have to figure out yourself is how to get at the JiraWorkflow. I, for example, extract the List by the following:

Collection<JiraWorkflow> workflows = workflowManager.getActiveWorkflows();

where I iterate all workflows and compare to the searched workflow name. From there on you can go through all actions (.getAllActions()) which give you the transition IDs.

My problem is, and I hope maybe someone else can answer it: How do you make a transition comment?

This:

issueInputParameters.setComment("TestComment");

 always gives me the validation error that I'm not permitted to add a comment to this issue, although the workflow user is admin and creator of the actual issue.
