Hi,

We are using the EMF Compare Structure Merge viewer, and noticed that the "Previous Difference" and "Next Difference" buttons behave slightly differently.

When navigating the differences using these buttons - "Next Difference" will expand the next tree node and select/reveal the difference there, whereas "Previous Difference" does not expand the previous node, it selects the previous difference in a tree node that has already been revealed.

Is this the expected behaviour, or should "Previous Difference" expand the previous tree item to reveal the difference there?

Hi Connor,

I believe the "expected" behavior should be to expand the items when navigating to previous differences as well, since what you describe means clicking on "previous" with a given difference selected will have different results according to the tree state, which doesn't seem like a good thing. Could you raise a bug for this?
