I get the following exception when a JFrame is opened with a number of text boxes and combboxes.....
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.JComponent._paintImmediately(JComponent.java:5085) at javax.swing.JComponent.paintImmediately(JComponent.java:4880) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:723) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:679) at javax.swing.RepaintManager.seqPaintDirtyRegions(RepaintManager.java:659) at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(SystemEventQueueUtilities.java:128) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:273) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:183) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:173) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:168) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:160) at java.awt.EventDispatchThread.run(EventDispatchThread.java:121)
I can't post the actual code of the JFrame....the application runs in Solaris. Please let me know if anyone else faced this problem and if there is any solution.
