[John Yesberg]

I have some spring bean definition XML files. When I double-click on one in the Package Explorer, it opens in a MyEclipse XML Editor. The file shows many validation warnings (eg. Referenced bean ‘sessionFactory’ not found) and errors (eg. parent bean ‘baseTransactionProxy’ not found). This is possibly related to the fact that this file is included by another file, and these various beans are defined in the other file.

The main problem, however, is that at various times, when I click in the file, or scroll the file, I get a popup dialog box headed “Error”, saying “An error has ocurred. See error log for more details. Reason: java.lang.NullPointerException”. If I click “Details >>”, I get no new information. The error log contains the following:

!ENTRY org.eclipse.jface 4 2 2007-08-09 12:20:50.374
!MESSAGE Problems occurred when invoking code from plug-in: “org.eclipse.jface”.
