TreeTableView: Selection is not restored correctly for nodes with a depth greater one

    XMLWordPrintable

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      windows_7

      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_112"
      Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
      Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Windows 10 x64

      A DESCRIPTION OF THE PROBLEM :
      When using a TreeTableView with default selection model, the selection is not restored reliably after sorting. The bug maybe related to JDK-8169642.

      REGRESSION. Last worked in version 8u112

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1) Execute the sample app (see sourcecode)
      2) Select node "1" and switch the sort order by clicking the column header
      -> The selection remains on node "1" -> OK
      3) Select node "1.1" and switch the sort order by clicking the column header
      -> The selection switches to "1.4" -> NOT OK

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      I expect the same node to be selected before and after sorting.
      ACTUAL -
      The selection is not restored correctly for nodes with a depth greater than one.

      REPRODUCIBILITY :
      This bug can be reproduced always.
