Screen shot of editor marging - missing line numbers
Theis window is generating NullPointerExceptions when I click on it from another window.
Hi, I was trying really hard to reproduce this bug in Windows system, but it didn't happen. I check the code and only reasonable fix was this: http://hg.netbeans.org/jet-main/rev/8042061fa087 If it doesn't help and do you have a time, so you can run netbeans with -J-Dorg.netbeans.modules.editor.lib2.view.DocumentViewOp.level=500 and then messages.log after NPE will be very helpful. Integrated into 'main-silver', will be available in build *201610250002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/8042061fa087 User: Milutin Kristofic <mkristofic@netbeans.org> Log: #257185 - NullPointerException at javax.swing.plaf.basic.BasicScrollPaneUI$Handler.mouseWheelMoved This issue is still present in NetBeans 8.2. I'm reopening since NetBeans' Exception Reporter keeps adding the reports to this issue, but still hasn't created a new issue for it (even though there have been hundreds of reports since this was marked as fixed). I also filed issue 269591 for this a couple of weeks ago, but nothing happened to it since. This issue causes: * line numbers to disappear * the editor to jump back to the top while scrolling * Find (Ctrl+F) to stop working * ... This bug already has 750 duplicates see http://statistics.netbeans.org/exceptions/detail.do?id=221015 The VERSION field corresponds to when this bug was first reported. Please do not alter its value. Hopefully fixed but I'm not able to reproduce the problem so please verify once the fix gets into dev builds. Thanks. http://hg.netbeans.org/jet-main/rev/a9d7d359f172 *** Bug 269591 has been marked as a duplicate of this bug. *** Integrated into 'main-silver', will be available in build *201703310002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/a9d7d359f172 User: Miloslav Metelka <mmetelka@netbeans.org> Log: #257185 - NullPointerException at javax.swing.plaf.basic.BasicScrollPaneUI$Handler.mouseWheelMoved. Please do not open issues that have been closed in past releases. If you are still experiencing this bug, please open a new bug report. This is happening in NetBeans 8.2 (JDK 1.8.0_144 and 1.8.0_131) so it should be reopened (or opened for NetBeans 8.2). When I submitted the exceptions through NetBeans 8.2, it assigned the reports to this bug. This was reopened automatically after submitting report. Here also in 8.2 This bug already has 2100 duplicates see http://statistics.netbeans.org/exceptions/detail.do?id=221015 Created attachment 165616 [details]
