Custom Field Type: "Version Picker" - Scroll Bar for displaying List Not Working

When a list is displayed (on an edit page) derived from the Project Managed Version's list using the "Version Picker" custom field, the right scroll bar for the displayed version picker list is not functional. My list currently has nine items in it. The scroll bar is not functional and the entire expanded list is displayed. This will be a problem going forward, as this list increases in size and the version picker field consumes more real estate on the page.

I need a custom multi-select version picker. There are two non-custom fields provided in JIRA that support this:

1. Affects Version/s

2. Fix Version/s

These non-custom fields provide the same functionality as the Version Picker and support the scroll bar. For some of my custom issue types, I can't use these fields because their names don't apply well to our project schemes.

Also refer to JSP-17190 and JRA-3028.

Thanks,
Joe
