Bug 98242 [Viewers] [Javadoc] clarify that StructuredViewer does not update sort order if null properties are given
Despite the specification of StructuredViewer.update(Object element, String[] properties) that specifiying null properties forces full update including sort order, the implementation in 3.1M6 calls internalUpdate() which inits needsRefilter to false if no properties are given. Thus a change to a relevant sort attribute of the element does not maintain sort order (e.g. on TreeViewer). Suggested fix: protected void internalUpdate(Widget widget, Object element, String[] properties) { boolean needsRefilter = true; if (properties != null) { needsRefilter = false; for (int i = 0; i < properties.length; ++i) { needsRefilter = needsRefilter(element,properties[i]);
