creating sub-tasks using scriptrunner

[Ron Grinfeld]

Using script runner custom field, I’m trying to create a specific subtask type if such doesn’t exists yet for the parent issue and if another custom filed is set with a value.

I’m getting into an endless run where it subtask are getting created endlessly.

Seems that there is a recursive event due to some multi-threading behavior that I’m not aware of.

My script is bellow, could you give it a look and let me know what I’m doing wrong?

You didn't say how you were running this, but the problem could be:

def mutableIssue = ComponentManager.getInstance().getIssueManager().getIssueObject(issue.id);

You should use the issue given to you in the script binding, eg 

def mutableIssue = issue

(although that's redundant, you could just replace mutableIssue with issue).

The problem might be that it doesn't "see" the subtasks unless the transaction is finished, as you are looking up the issue from the db, so it endless thinks there are no matching subtasks. When you modify it by eg adding a link, it's kicked off again (I'm guessing this is a listener?).

I'm using this script in a script runner custom field and not a workflow, so the issue is given. How can I tackle the fact that it doesn't "see" the sub task? Basically I'm trying to have a Yes/No filed that based on its value a "Documentation" sub-task will be added/removed.

You just can't update the current issue in a field... you need a listener.

OK, so on the same topic, how do I set a custom list field to a specific list option value ? Ii have a field named DocReq which have the values 'None' (the default system one) and "Required"
