https://bugs.openjdk.java.net/browse/JDK-8233040
The issue is that the eventFilter in CBPC uses F4 for toggling the popup _and_ consumes it. This prevents client code to register there own filter. The fix was to remove the block entirely - F4 is already handled by a keyMapping in ComboBoxBehaviorBase. Added test that fails before the change and passes after, old tests are all passing. ---------------- Commits: - 2f015406: Fix: ComboBoxPopupControl - remove eventFilter for F4 Changes: https://git.openjdk.java.net/jfx/pull/28/files Webrev: https://webrevs.openjdk.java.net/jfx/28/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8233040 Stats: 159 lines in 2 files changed: 153 ins; 6 del; 0 mod Patch: https://git.openjdk.java.net/jfx/pull/28.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/28/head:pull/28 PR: https://git.openjdk.java.net/jfx/pull/28
