When you
navigate multiple locations in a merge point using the
Next Location button, you may select a difference
whose location is hidden in the merge output pane. Because the merge
output display depends on top-down merging, some input nodes cannot be represented
until some level of resolution has occurred. To indicate this condition, the
ancestor node is shown in the merge output pane with the hidden background
color.
The following steps illustrate how to detect and work with a hidden
merge point.
- In the first figure, a merge point with multiple locations has been selected.
As a result, the
Next
Location button in the toolbar is enabled. The hover help and contributor pane selections
show that the unresolved difference is a section element.
- Now, assume that you click the Next Location button
to see the next location. When a hidden node is encountered, the next location
is not automatically selected. Instead, the following window
is displayed:
- Click No to navigate to the actual node location.
As the next figure shows, the section node is visible in the input
contributors. But in the merge output pane, it is not:
In the merge output pane, the merge point is
highlighted with the hidden background color: This indicates that the selected
node does not correspond to this merge output node, but to a node within the
subtree. The nearest ancestor is typically a merge point or resolved placeholder.
- Click Yes to resolve this difference in the normal
top-down fashion. This option automatically selects the merge point that should
be resolved first: the nearest ancestor that does not exist in the merge output.
This is typically a merge point or resolved placeholder. In this case, the
nearest unresolved ancestor of the section node, the Texts node,
is selected:
