Same child, different parents in a TreeViewer

I have a JFace TreeViewer where the structure is such that a child can have several parents.

When selecting a child in the viewer, I want to get the parent of that selection.

Example, with the following structure: 

- parent1
    - child
- parent2
    - child

When the bottom row is selected, I want to retrieve parent2, but child.getParent() only gives me the first occurrence of a parent, and does not take which branch I selected in the tree.

Create one marker interface and make all root to implement that interface and on run time add different root model.

The Tree Viewer model doesn't support this.

You will have to add additional methods to your content provider class to return the additional parents.
