Turns out it's a duplicate of https://jira.atlassian.com/browse/JRASERVER-5225, so closing this one 

I'm reopening the issue as per comment  https://jira.atlassian.com/browse/JSWSERVER-16018?focusedCommentId=1596212&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-1596212.

The issue JRASERVER-8818 "have subtask inherit component of parents" was marked as duplicated by this issue. However, it seems subtasks still do not inherit the parent component. That is, the component is not set by default to that of the parent. It should be.

Given that this issue, JRASERVER-6398, is marked as resolved while the issue JRASERVER-8818 still exists (at least in my cloud instance), perhaps JRASERVER-8818 should be reopened?

HI Guys 

Faced this situation but came up with a solution that meet this requirement using scriptrunner.

so for those of you that already have this plugin you can look at this : https://scriptrunner.adaptavist.com/5.0.4/jira/recipes/behaviours/subtask-default-fields.html

For those of you that do not know about it, you can still take a look at it, and give it a try

.

We were also looking for a way to copy fields from Header Jiras into Sub-task Jiras.

We are using the method described by 'Tim Bray added a comment - 09/Feb/10 3:47 PM'

This is working for us. We saw an error if any user attempted to edit a Jira, a re-boot of our JIRA server fixed this error.

Hi guys,

We are currently doing some JIRA house keeping and I will be closing this issue as a duplicate of JRA-5225. I will also add those watching this issue to the main request.

Those of you that have not voted on JRA-5225 may also like to recast your vote there.

The JSS plugin and Minyaa suite plugin both use post-functions to set values. The original description of this issue, however, focused on setting default values during the creation step (i.e. using the parent issue to determine which values should be selected by default when the user sees the create issue screen).

None of the solutions discussed here seem to address the original requirement. Has anyone found a way to do this?

Hi All,

In order to resolve such issues, Minyaa comes with a set of Post-Functions.
Be able to inherit fields from Parent Issue is usefull, but you may need to update Sub-Task when Parent Issue fields change !

For inheritance ...

• Priority Inheritance
• Components Inheritance
• Affected Version Inheritance
• Fix Version Inheritance
• CustomFields Inheritance
  

For propagation on Sub Task

• Affected Version Propagation
• Fix Version Propagation

For propagation on any Linked Issue

• CustomFields Propagation
