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.

if (node instanceof IPropertySheetEntry) {
			entry = (IPropertySheetEntry) node;
		} else {
			category = (PropertySheetCategory) node;
		}
        boolean hasPlus = item.getItemCount() > 0;
        boolean needsPlus = category != null || entry.hasChildEntries();
        boolean removeAll = false;
        boolean addDummy = false;
        if (hasPlus != needsPlus) {
            if (needsPlus) {
                addDummy = true;
            } else {
                removeAll = true;
            }
        }
        if (removeAll) {
            
            TreeItem[] items = item.getItems();
            for (int i = 0; i < items.length; i++) {
                removeItem(items[i]);
            }
        }
        if (addDummy) {
            new TreeItem(item, SWT.NULL); 
            
        }
    }
}
