Restrict creating sub task unless parent task field is set to some value


I need to restrict users from creating a sub task until a value in the parent it set to 'Yes'.

I am using the following on the validator for the Create Issue transition on the subtask. It doesnt allow me to create the subtask even when parent it set to 'Yes' :

transientVars["issue"].getCustomFieldValue("custom field name") == 'Yes'

Is there a way to do this?


Thank you in advance.

Hrm... your code is not checking the parent issue though.

The intuitive answer would be to use a validator something like this:

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def cf = customFieldManager.getCustomFieldObjectByName("My Custom Field")
issue.parentObject.getCustomFieldValue(cf) == "Yes"

but I don't think that's going to work, because the link between parent and child won't be created until after the issue is committed.

But you can try it. I suspect it will give a null reference error, as parentObject will be null.


issue.parentObject.getCustomFieldValue(cf) == "Yes"

is only correct for getting text field values, if it's a select list or radios use:

issue.parentObject.getCustomFieldValue(cf)?.value == "Yes"

I think I would use the "behaviours" aspect of script runner to put a red warning on the form and make all fields read-only. JIRA really needs permissions per issue type.
