Bug 58845 [Viewers] Error while debugging but no log
I was debugging an IllegalArgumentException. I clicked on one of the traceback lines after the breakpoint was hit and got a dialog informing me that an error occurred and that I should see the log for details but the log was empty. After this, the debuuger no longer opens files (i.e. it still stps at breakpoints but I can't look at the source). I am using Eclipe build I20040413 and IBM VM build 1.4.1, J2RE 1.4.1 IBM build cxia321411-20040301.

* This does not handle structural changes (e.g. addition or removal of elements),
 * and does not update any other related elements (e.g. child elements).
 * To handle structural changes, use the <code>refresh</code> methods instead.
 * </p>
 * <p>
 * This should be called when an element has changed in the model, in order to have the viewer
 * accurately reflect the model.  This method only affects the viewer, not the model.
 * </p>
 * <p>
 * Specifying which properties are affected may allow the viewer to optimize the update.
 * For example, if the label provider is not affected by changes to any of these properties,
 * an update may not actually be required. Specifing <code>properties</code> as 
 * <code>null</code> forces a full update of the element.
 * </p>
 * <p>
 * If the viewer has a sorter which is affected by a change to one of the properties,
 * the element's position is updated to maintain the sort order.
 * </p>
 * <p>
 * If the viewer has a filter which is affected by a change to one of the properties,
 * the element may appear or disappear if the change affects whether or not the element
 * is filtered out.
 * </p>
 *
 * @param element the element
 * @param properties the properties that have changed, or <code>null</code> to indicate unknown
