Bug 189999 [PropertiesView] [PropertiesView] Setting 1 value causes very slow recursive refresh
I have a properties with a hierarchy. Everything is read-only except for the leaf nodes. Setting a value takes about 5 seconds on my Core2Duo and seems to have possibly gotten even slower in RC2. This stems from the call to PropertySheetEntry.refreshFromRoot in the setValue method. Why should 1 value cause a total refresh? If other values were dependent, shouldn't they have listeners? This is a big problem for me as it will be very hard for my users to be productive with such a slow interface. I realize its late to get something in for 3.3. If there is a workaround, I would really like to know about it so I don't have to reimplement the property view.

TreeItem[] childItems = getChildItems(widget);
        
        TreeItem item = null;
        if (widget instanceof TreeItem) {
            item = (TreeItem) widget;
        }
        if (item != null && !item.getExpanded()) {
            
            for (int i = 0; i < childItems.length; i++) {
                if (childItems[i].getData() != null) {
                    removeItem(childItems[i]);
                }
            }
            
            if (category != null || entry.hasChildEntries()) {
                
                
                
                
                
                
                
                childItems = getChildItems(widget);
                if (childItems.length == 0) {
                    new TreeItem(item, SWT.NULL);
                }
            }
            return;
        }
