This PR fixes an issue with selection of multiple items in TableView and TreeTableView controls that gets moved unexpectedly when new items are added even way below the selected items.
A couple of tests have been added. They fail without this PR (first selected item gets deselected, and table anchor gets moved), and pass with this PR (first selected item keeps selected, and table anchor remains at the same place). ------------- Commit messages: - Only shift anchor if existing one is affected by the change event, and tests Changes: https://git.openjdk.java.net/jfx/pull/790/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=790&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8284665 Stats: 100 lines in 4 files changed: 98 ins; 0 del; 2 mod Patch: https://git.openjdk.java.net/jfx/pull/790.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/790/head:pull/790 PR: https://git.openjdk.java.net/jfx/pull/790
