Automatically Setting Version Based on Component

In this scenario tester is setting bundle version on the issue. He doesn't have knowledge to determine which component issue belongs to, but he knows which higher level version (bundle version) he is testing. Assignee analyses the issue and assigns a component to issue. We want affects version to be automatically set based on bundle version and component. From the bundle version we can automatically detect which component versions are there in the bundle and as soon as a component is set on the bundle we should be automatically set affect version by searching the component inside the bundle.
