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.

Object el = children.get(i);
            if (!set.contains(el)) {
				createItem(el, widget, i);
			}
        }
        
        if (widget == tree && oldCnt == 0 && tree.getItemCount() == 1) {
            tree.setRedraw(false);
            tree.setRedraw(true);
        }
        
        childItems = getChildItems(widget);
        
        
        
        for (int i = 0; i < newSize; i++) {
            Object el = children.get(i);
            if (el instanceof IPropertySheetEntry) {
				updateEntry((IPropertySheetEntry) el, childItems[i]);
			} else {
                updateCategory((PropertySheetCategory) el, childItems[i]);
                updateChildrenOf(el, childItems[i]);
            }
        }
