Pre-populate sub-task fields from parent Edited

I'm trying to follow an example provided here, to pre-populate sub-task issue fields upon creation (because some of them are required).

However code, as well as description, refres to parentIssueId field which should be present on form. But how does one gets the value of a parent issue ID when sub-task is just being created?

What I'm trying to do is to pre-populate several fields from the parent issue when Create is being called, so the script to appear in Initializer section, without a need to trigger or change anything from end user.

You cannot do this. As we specified in the article that you are referencing to:

"This script hinges on the parentIssueId being present in the form. As such, you will need to associate the script with a visible field. It will not work as an initialiser."

You can see this as a warning in the article:

So to solve your issue all you have to do is not use it as an initialiser, since they are loaded before the form is populated.

But how parentIssueId field is populated with its value? Is it like an internal name which is being auto-populated by JIRA one field with such name appears on a form?

I don't actually know how it works, since that is on JIRA's side. But think of it this way:

When the form is loaded, these things happen.

1. A request is sent.

2. Behaviours load.

3. Behaviours execute initialisers. 

4. Jira loads data into the form. This includes things like the project and such.

5. Rest of behaviours are executed.

6. Behaviours await triggers from the user.

So as you can see, the initialisers are loaded before the data of the server is parsed into the form. The problem is that parentIssueID is populated at step 4. Do you understand what I mean?
