#181 Filter in DataTreeListView-Sample buggy

[Chris]

In ObjectListView Demo:

1) open the DataTreeListView-Tab
2) type in the filter the word "Ike"
-> All records are filtered, none is displayed (imho incorrect)
3) delete the filter
4) open "Jonathan Philip Piper"
5) type in the filter the word "Ike"
-> Now 3 records are displayed (imho correct, but there would be more)
6) Select [-] on "Jonathan Philip Piper"
-> All records disappear

When filtering in a treeview, imho all records needs to be searched and the record and all its parents need to be displayed (like all folders would be unfolded ([+]) and then filtered)

PS: I have no clue, whether priority 1 or 9 is the highest. It would be low prio.
