TableView is not displayed after refresh() with fixedCellSize set

    Details

    • Introduced In Version:
    • CPU:
      x86_64
    • OS:
      windows_7

      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_102"
      Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
      Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      EXTRA RELEVANT SYSTEM CONFIGURATION :
      Windows 7 x64 SP1

      A DESCRIPTION OF THE PROBLEM :
      I have a test case, which demonstrates the situation, when the content of a TableView is not displayed properly. The table shows completely white rectangle, while it should show the data and the grid. This happens when I do refresh() after removing most of the columns.


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1) start the test case
      2) scroll the table horizontally to the most right
      3) press the button "Hide [1-99]".

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Col 00 with data and grid is shown
      ACTUAL -
      Col 00 is shown, but there is no data or grid displayed.

      One have to click in the table or scroll or touch a column for the content to appear.

      REPRODUCIBILITY :
      This bug can be reproduced always.
