#4 Wrong entry loaded from search results

[Joachim Gabler]

After a search by index entries (e.g. search for
person) a list of the index entries found matching the
search criteria is displayed as tree nodes. Opening the
node shows the entries associated with the index entry.

Clicking on the node itself will load any entry, but
should instead open the tree node and show the leafs.
If no entries are associated with the index entry, an
error message should be displayed.
