The issue describes the makroscopic effect/s, namely content showing in cells that are off range.
The base reason is missing cleanup of the cell on transition from not-empty to empty when the old item is a null contained in the items. Fixed by changing the logic to cope with that special case. Added tests that fail before and pass after the fix. ------------- Commit messages: - 8251941: ListCell: visual artifact when items contain null values Changes: https://git.openjdk.java.net/jfx/pull/288/files Webrev: https://webrevs.openjdk.java.net/jfx/288/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8251941 Stats: 90 lines in 2 files changed: 87 ins; 0 del; 3 mod Patch: https://git.openjdk.java.net/jfx/pull/288.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/288/head:pull/288 PR: https://git.openjdk.java.net/jfx/pull/288
