When I did that, nothing was restored in JOSM. Then, for the fun of it, I just hit Ctrl-A to see if I could somehow select it if it was really un-deleted, but wasn't shown. When I did that, JOSM threw up an error message. {{{ Repository Root: http://josm.openstreetmap.de/svn Build-Date: 2010-12-24 02:31:25 Last Changed Author: Upliner Revision: 3740 Repository UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b URL: http://josm.openstreetmap.de/svn/trunk Last Changed Date: 2010-12-23 15:38:34 +0100 (Thu, 23 Dec 2010) Last Changed Rev: 3740 Identification: JOSM/1.5 (3740 en) Memory Usage: 94 MB / 455 MB (33 MB allocated, but free) Java version: 1.6.0_23, Sun Microsystems Inc., Java HotSpot(TM) 64-Bit Server VM Operating system: Windows 7 Dataset consistency test: [COMPLETE WITHOUT COORDINATES] {Node id=-1 version=0 MVT } is not incomplete but has null coordinates Exception during dataset integrity test: java.lang.NullPointerException at org.openstreetmap.josm.data.osm.DatasetConsistencyTest.searchNodes(DatasetConsistencyTest.java:82) at org.openstreetmap.josm.data.osm.DatasetConsistencyTest.runTest(DatasetConsistencyTest.java:143) at org.openstreetmap.josm.data.osm.DatasetConsistencyTest.runTests(DatasetConsistencyTest.java:157) at org.openstreetmap.josm.actions.ShowStatusReportAction.getReportHeader(ShowStatusReportAction.java:69) at org.openstreetmap.josm.tools.BugReportExceptionHandler.handleException(BugReportExceptionHandler.java:94) at org.openstreetmap.josm.tools.BugReportExceptionHandler.handle(BugReportExceptionHandler.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at java.awt.EventDispatchThread.handleException(Unknown Source) at java.awt.EventDispatchThread.processException(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Plugin: Create_grid_of_ways (21706) Plugin: OpeningHoursEditor (24290) Plugin: RoadSigns (22850) Plugin: alignways (24815) Plugin: buildings_tools (23804) Plugin: colorscheme (21563) Plugin: download_along (22427) Plugin: imageryadjust (24866) Plugin: measurement (22547) Plugin: michigan_left (22369) Plugin: openstreetbugs (23747) Plugin: openvisible (21706) Plugin: osmarender (22765) Plugin: restart (24396) Plugin: reverter (23278) Plugin: routing (23561) Plugin: tageditor (21026) Plugin: tagging-preset-tester (22454) Plugin: terracer (24713) Plugin: turnrestrictions (24125) Plugin: undelete (22365) Plugin: utilsplugin2 (24792) Plugin: walkingpapers (22549) Plugin: waydownloader (21706) Plugin: wayselector (23103) java.lang.NullPointerException at org.openstreetmap.josm.data.osm.visitor.paint.MapPaintVisitor.drawNode(MapPaintVisitor.java:114) at org.openstreetmap.josm.data.osm.visitor.paint.MapPaintVisitor.visitAll(MapPaintVisitor.java:660) at org.openstreetmap.josm.gui.layer.OsmDataLayer.paint(OsmDataLayer.java:268) at org.openstreetmap.josm.gui.MapView.paintLayer(MapView.java:448) at org.openstreetmap.josm.gui.MapView.paint(MapView.java:527) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JSplitPane.paintChildren(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JComponent.paintToOffscreen(Unknown Source) at javax.swing.RepaintManager$PaintManager.paintDoubleBuffered(Unknown Source) at javax.swing.RepaintManager$PaintManager.paint(Unknown Source) at javax.swing.RepaintManager.paint(Unknown Source) at javax.swing.JComponent._paintImmediately(Unknown Source) at javax.swing.JComponent.paintImmediately(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.seqPaintDirtyRegions(Unknown Source) at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) }}} Then JOSM kept throwing up more error messages making it almost impossible to shut it down. And every time I looked at the error report, it was different from the last! So, I found a major cascading bug that could annoy the heck out of anybody because it never ends! (if it ends on your end, you got lucky) The only way I could get JOSM to close was to crash Java via the task manager, hence the ""Blocker"" tag." defect new blocker Plugin undelete latest undelete; relations; cascading error messages
