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 (category == null) {
                    category = new PropertySheetCategory(categoryName);
                    categoryCache.put(categoryName, category);
                } else {
                    categoriesToRemove.remove(category);
                }
                category.addEntry(childEntry);
            }
        }
        
        if (addMisc) {
			categoryCache.put(MISCELLANEOUS_CATEGORY_NAME, misc);

        ArrayList categoryList = new ArrayList();
        Set seen = new HashSet(childEntries.size());
        for (int i = 0; i < childEntries.size(); i++) {
            IPropertySheetEntry childEntry = (IPropertySheetEntry) childEntries
                    .get(i);
            String categoryName = childEntry.getCategory();
            if (categoryName != null && !seen.contains(categoryName)) {
                seen.add(categoryName);
                PropertySheetCategory category = (PropertySheetCategory) categoryCache
                        .get(categoryName);
                if (category != null) { 
                    categoryList.add(category);
