[BUG] getLinkTarget active state for occurrences in same deployment

[roleyfoley]

Current Behaviour

When linking to an occurrence in the same deployment the link isn't considered to be Active. This means that references aren't resolved as expected when working with link resources

Expected Behaviour

When linking between occurrences in the same deployment the state of the occurrence should be available to support the use of getReference calls

Possible Solution

When evaluating the active state of an link check to see if the occurrences have the same deployment unit and group. If they do mark it as active.

Steps to Reproduce

1. Create two components ( s3 components ) and use the same deployment:Unit value
2. Link between the two components
3. Generate the template and you will find that they treat each other as inactive
