Issue: When tabs are permuted as mentioned in the issue description as, 1. TabPane.getTabs().setAll(tab0, tab1) 2. TabPane.getTabs().setAll(tab0, tab1, tab2, tab3); the tab headers do not get permuted in same order as `TabPane.getTabs()`.
=> tab headers should be shown in order as tab2, tab3, tab0, tab1. => But should are show in order as tab0, tab1, tab2, tab3 Cause: Newly added tabs(tab2, tab3) are not inserted at correct index. The index `Change.getFrom()` (0) used from Change does not remain valid after the tabs to be moved(tab0, tab1) are removed from `tabsToAdd` list. Fix: Use the index of first newly added tab, from `TabPane.getTabs()`, which would be always reliable. Verification: No existing tests fail due to this change. Added a system test which fails without and pass with fix. ------------- Commit messages: - 8237602: TabPane doesn't respect order of TabPane.getTabs() list Changes: https://git.openjdk.java.net/jfx/pull/201/files Webrev: https://webrevs.openjdk.java.net/jfx/201/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8237602 Stats: 71 lines in 2 files changed: 65 ins; 2 del; 4 mod Patch: https://git.openjdk.java.net/jfx/pull/201.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/201/head:pull/201 PR: https://git.openjdk.java.net/jfx/pull/201
