IllegalStateExecption #69

Closed PSRCode closed 6 years ago

PSRCode commented 6 years ago

Not sure how I got that:

Exception in thread "JavaFX Application Thread" java.lang.IllegalStateException: flow.firstVisibleCell must not be null at org.lttng.scope.views.events.EventTable.getVisibleRowIndices(EventTable.kt:147) at org.lttng.scope.views.events.EventTable.access$getVisibleRowIndices(EventTable.kt:40) at org.lttng.scope.views.events.EventTable$selectIndex$1.run(EventTable.kt:119) at com.sun.javafx.application.PlatformImpl.lambda$null$117(PlatformImpl.java:295) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl.lambda$runLater$118(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) at com.sun.glass.ui.gtk.GtkApplication._runLoop(Native Method) at com.sun.glass.ui.gtk.GtkApplication.lambda$null$450(GtkApplication.java:139) at java.lang.Thread.run(Thread.java:748)

Did you get that soon after opening or closing a project? I see where there could be a race condition on view creation or teardown. I could push a fix to avoid that particular NPE, but would like to be sure it is not due to something else.

Let's go with this fix, let me know if it happens again.
