How to find all linked issues to Epics that have a component?

Question

From my understanding, all issues created under an Epic do not inherit the component of the parent Epic.

Let's say I tag certain epics with component "projectA", but all my linked stories are not tagged. Could I use JQL to find all stories within all the epics tagged with component "projectA"?

I'm on OnDemand for JIRA.

Please try:
issueFunction in linkedIssuesOf("component = projectA", "is Epic of")
using Script Runner

You cannot do that with a single jql query. THink about creating a script that will do that through iteration (find epics with project A and search for the child of each) or creation of gadget that will do the same job.

Thanks for replying Alexey. This only gives me the Epic tagged "Project A", but not the issues that are children of that.

I clarified the question a bit more above.
